PDRN Injections vs Topical PDRN Serum: What’s the Difference and Which Is Right for You?

PDRN has arrived in two very different places at once. In clinic rooms across the US, it is being injected into the skin by aesthetic practitioners under names like polynucleotide skin boosters and salmon sperm facials. On bathroom shelves, it is showing up as a topical serum you apply after cleansing. Both use the same headline ingredient. They are not the same thing, and they do not do the same job.

This article puts the two side by side on the factors that actually decide the question: cost, results timeline, downtime, comfort, safety and the evidence behind each. We will cover what happens during a course of PDRN injections, what a topical PDRN serum can realistically do from the surface down, and where each one genuinely fits. There is no verdict here that one is categorically better than the other. That is not a useful answer, because the right choice depends on your budget, your skin goals and how much clinical commitment you want to take on.

For transparency before we start: our own PDRN Serum contains 20,000 PPM (2%) vegan INJIN PDRN and costs $18 for 30ml. If you want the full ingredient science before you get into the comparison, our complete PDRN ingredient guide covers the mechanism in depth. Before comparing delivery methods, though, it helps to be clear on what PDRN actually is.

What PDRN Is, and Why It Shows Up in Two Very Different Places

PDRN stands for polydeoxyribonucleotide. In plain English, these are short chains of DNA fragments that act as signals, telling skin cells to get on with repair and renewal. They are not doing anything exotic. They are speaking to your skin in a language it already understands, prompting the cell activity that naturally slows down with age.

If you want to check whether a product genuinely contains it, look for Hydrolyzed DNA on the ingredients list. That is how PDRN appears under INCI naming conventions, which are the standardized ingredient names required on packaging. Knowing this is genuinely useful, because it lets you verify a claim on the front of a bottle against the list on the back.

PDRN comes from two possible sources. The traditional route is animal-derived, most commonly from salmon DNA, which is where the salmon association in all those treatment names comes from. The newer route is vegan and plant-derived. Ours is INJIN Vegan PDRN, extracted from Artemisia capillaris. If you want the full comparison between salmon-derived and vegan PDRN in products, we have covered that properly in Salmon Sperm Serum: What Is It, Does It Work and Is Vegan PDRN Better?.

Here is the part that explains everything that follows. PDRN did not start life as a skincare ingredient. It was developed and used in clinical medicine for wound healing and tissue repair, which meant it was delivered by injection from the beginning. That is simply how it was designed to be administered. It only became viable in topical skincare once formulators worked out how to produce low molecular weight PDRN, small enough to be useful when applied to the surface of the skin rather than placed underneath it. The injectable came first by a considerable margin. The serum is the newer arrival, and it exists because of a formulation breakthrough rather than a marketing decision.

One more piece of vocabulary that will save you confusion when researching treatments. You will see clinics advertising polynucleotides and other clinics advertising PDRN, and you will reasonably wonder whether these are different things. In most clinic menus they are used to mean the same category of DNA-fragment based skin booster. There are technical distinctions in fragment length, but for a consumer comparing treatment options, treat the two words as pointing at the same shelf. For a deeper explainer on the ingredient itself, read what is PDRN in skincare: benefits, science and how it works.

The injectable route is where PDRN built its reputation and its evidence base, so that is where the comparison starts.

PDRN Injections and Salmon Sperm Facials: What Happens in Clinic

A PDRN injectable treatment is administered by a licensed medical professional or a trained aesthetic practitioner. The PDRN solution is injected intradermally, meaning into the dermis, using a very fine needle across the face in a standardized pattern. Many practitioners use the nappage technique, a series of shallow, closely spaced micro-injections that distribute the product evenly rather than depositing it in one place. A typical full-face session uses around 2ml of product.

The meaningful difference, and the one worth holding onto for the rest of this article, is depth. An injection places the ingredient directly into the dermis. It bypasses the skin surface entirely. Nothing has to be absorbed, because the barrier has been physically crossed. That is a genuinely different intervention from anything applied on top of the skin, and it is the reason the two routes produce different kinds of results.

The naming confusion is real, and worth untangling

In the US, these treatments are marketed under a whole spread of names: bio-revitalization, skin rejuvenation injections, polynucleotide skin boosters, salmon DNA microneedling and, most searched of all, the salmon sperm facial. That last term deserves honesty, because it is used very loosely.

A salmon sperm facial can mean injections of PDRN. It can also mean microneedling, where a device creates controlled micro-channels in the skin, followed by a PDRN topical applied into those channels. Those are two different procedures, with different techniques, different practitioner requirements and noticeably different price points. If you book one expecting the other, you will be surprised. Ask the clinic to specify exactly which procedure you are booking and exactly which product they are using. If you are researching salmon-derived PDRN as a product rather than as a treatment, our salmon sperm serum guide is the more relevant read.

The protocol and what it is used for

Injectable PDRN is not a one-off. The standard protocol is 3 to 4 sessions spaced roughly 3 to 4 weeks apart. Early improvement is commonly reported from around 6 weeks, with fuller results around the 12 week mark, followed by maintenance sessions to hold the effect.

Practitioners use it for skin laxity and loss of elasticity, fine lines, dullness and dehydration, photodamage from sun exposure, and to support recovery after other aesthetic procedures. It is generally positioned as a quality-of-skin treatment rather than a volumizing one, which is what distinguishes it from a filler.

The evidence base is genuinely strong

This is where injectable PDRN earns its reputation, and it would be dishonest to downplay it. A double-blind, randomized, placebo-controlled trial of 48 subjects with moderate photoaging measured PDRN against a saline placebo and found improvements in skin elasticity, hydration and surface roughness at 12 weeks. No serious adverse events were recorded. Transient redness and mild swelling resolved within 48 hours. You can read a summary of that PDRN skin rejuvenation clinical evidence.

That single trial does not sit alone. A broader systematic review of polynucleotides in esthetic medicine, published in the Journal of Cosmetic Dermatology in 2025, assessed the effectiveness of polynucleotide treatments across the available literature, and a further review of polynucleotides in aesthetic medicine published in the International Journal of Molecular Sciences in 2024 examined current practices and perceived effectiveness in the field. The peer-reviewed literature on injectable polynucleotides is real and growing. Anyone telling you otherwise is not being straight with you.

The US regulatory position, stated plainly

Here is something you should know before you book, framed as information rather than a warning. Injectable PDRN and polynucleotide products are not FDA-approved for aesthetic injection in the US. Clinics offering these treatments are therefore working off-label or using compounded product. This is confirmed in provider guidance from the International Association for Physicians in Aesthetic Medicine.

This is not a reason to avoid the treatment, and plenty of widely used aesthetic procedures involve off-label application by experienced practitioners. It is a reason to ask a direct question at consultation: which product are you using, where is it sourced, and what is its regulatory status here? A good practitioner will answer that without hesitation. Ask about credentials in the same conversation.

The practical commitment

Beyond the clinical detail, be realistic about what the treatment asks of you. You need to find a genuinely qualified practitioner, which is easier in some cities than others. You need to book and attend multiple appointments across a 9 to 12 week window. And you need to plan around up to 48 hours of redness and mild swelling after each session, which for most people means not scheduling an appointment the day before something important.

Clinical results come with a clinical price tag, and for most people that is where the decision actually gets made.

What PDRN Treatments Actually Cost in the US

US clinic pricing for PDRN varies enormously, and anyone quoting you a single national figure is oversimplifying. The ranges below reflect current US market pricing and are worth treating as a starting point for your own local research rather than a fixed quote.

Injectable PDRN and polynucleotide skin boosters typically run around $400 to $1,200 per session for full face, with some clinics quoting from $200 to $500 for a single syringe or a partial-face treatment. Because the protocol calls for 3 to 4 sessions, a full course commonly lands somewhere between $1,500 and $4,800. Adding the neck pushes that higher again, with combined face and neck sessions frequently quoted well above the full-face rate.

Microneedling with PDRN, marketed as a salmon sperm facial or salmon DNA facial, generally sits around $450 to $900 per session in most cities. In premium urban markets such as New York, Los Angeles and Miami, that climbs to $1,200 to $1,500 and sometimes beyond.

Topical-only PDRN facials in clinic, where the product is applied to the surface without needles, are the most accessible clinical option at roughly $200 to $400 per session.

Why the range is so wide

Several variables move the number, and understanding them helps you read a quote properly. The number of syringes used is the biggest driver on the injectable side. Whether you are treating face only or face and neck changes the volume required. Provider credentials matter, and a board-certified dermatologist will typically charge more than a medspa esthetician. Whether the PDRN is combined with a device such as microneedling, radiofrequency or a laser adds significant cost. And geography does a lot of work, with the same treatment priced very differently in Manhattan and in a mid-size Midwestern city.

There is also what the sticker price hides. A single session figure is rarely what you actually spend. You are committing to a course of 3 to 4, then maintenance every 6 to 12 months as results gradually fade. Add travel, parking and time away from work across a 9 to 12 week window, and the real cost of a year of PDRN injections is meaningfully higher than the headline per-session price.

The honest contrast

Our PDRN Serum is $18 for 30ml. It is also available on Amazon US.

The arithmetic is obvious, and it would be easy to be smug about it. We would rather be accurate.

Injections and serums are not a like-for-like swap. One is a clinical procedure delivered into the dermis by a trained professional. The other is a daily habit you do at your bathroom sink.

For the price of one clinic session you could maintain a daily topical PDRN routine for a very long time. That is true, and it matters if budget is your constraint. But you are also buying a different intervention, operating at a different depth, with a different scale of effect. A serum works from the surface down. An injection starts underneath. Anyone who tells you a $18 serum replicates a $4,000 course of injections is selling you something.

We have made this clinic-prices-versus-accessible-skincare argument before, in the context of exosome treatments, in The Glow Revolution. The principle is the same: understanding what you are paying for is what lets you decide whether it is worth it.

Which raises the obvious follow-on question. If the injectable is the version with the strong clinical trials behind it, can a topical do anything meaningful at all?

Does PDRN Work Topically? What the Formulation Science Says

Yes, but with a genuine and important condition attached: it depends almost entirely on molecular weight and concentration. A PDRN serum that gets both right can do real work. One that gets either wrong is an expensive moisturizer with a good ingredient list. The skepticism behind this question is fair, so let us answer it properly.

Molecular weight decides whether anything happens at all

Your stratum corneum, the outermost layer of the skin, is a tightly organized barrier. It is very good at its job, which is keeping things out. Large, heavy molecules do not get meaningfully past it, and standard PDRN fragments are large.

This is why low molecular weight PDRN exists. By reducing the fragment size, formulators produce a version engineered to penetrate beyond the surface layer rather than sitting on top of it. This is established formulation science that applies across cosmetic chemistry, not a claim invented for marketing purposes. Research into polydeoxyribonucleotide extraction and its application in cosmeceuticals reflects how much of the current work in this space is focused on exactly this problem. If a PDRN serum does not tell you it uses low molecular weight PDRN, that omission is informative.

Concentration, and why PPM is the number to look for

PPM means parts per million, a unit for measuring how much of an ingredient is in a formula. 10,000 PPM equals 1%. It is a precise way of stating concentration, and precision is exactly what most of this category avoids.

Here is the uncomfortable truth about the current PDRN serum market: most products do not disclose their concentration at all. They put the ingredient on the front of the pack and stay quiet about how much is in there. A token inclusion, present at a fraction of a percent purely so it can be named on packaging, does very little for your skin. Without a disclosed number, you have no way to tell the difference between a meaningful concentration and a marketing gesture.

What to actually look for in a PDRN serum

If you are trying to work out which is the best PDRN serum for you, ignore the packaging and use criteria instead. Look for:

1. A disclosed concentration, stated in PPM or percent. If it is not on the page, ask why.
2. A clinically tested ingredient, not just a clinically tested finished formula. These are different standards of evidence.
3. Low molecular weight PDRN, so the molecule has a realistic chance of getting past the surface.
4. A clear source, ideally vegan and plant-derived if that matters to you.
5. Suitability for daily AM and PM use, because with PDRN, consistency is the entire point.

Our formula, stated factually

The PDRN Serum contains 20,000 PPM (2%) INJIN Vegan PDRN, low molecular weight, plant-derived from Artemisia capillaris. It is also available on Amazon US.

Alongside the PDRN, an 18% emollient blend of propylheptyl caprylate, shea butter and sunflower seed oil delivers the instant glass skin glow, and glycerin provides hydration. PDRN supports your skin’s natural collagen and hyaluronic acid levels, which is what leads to skin feeling smoother and bouncier over time, and it supports skin cell renewal.

The practical details: pH 4.0 to 4.5, fragrance-free, vegan, confirmed safe during pregnancy and breastfeeding, suitable for AM and PM use, and it layers with retinol, AHAs, BHAs and Vitamin C. It is $18 for 30ml and rated 4.8 out of 5 by verified reviewers.

Where the numbers come from, and what to expect

We are careful about attribution, because this category is not always careful about it. The performance figures for 2% INJIN PDRN come from clinical studies run by the ingredient supplier. Based on clinical studies completed using 2% INJIN PDRN (Polydeoxyribonucleotide), run by the ingredient supplier. That is supplier data, not independent third-party research, and we label it that way every time it appears. Coverage of PDRN skincare in the wider beauty press, including Allure’s reporting on the ingredient, reflects how quickly this category has grown, which is all the more reason to be precise about what is proven and by whom.

On expectations, there are two distinct things happening and it is worth separating them. From the very first use you get an instant glass skin effect, and that is the emollient blend doing its job cosmetically, smoothing and adding light-reflecting glow. That is immediate and real, but it is a surface effect. The longer-term change, skin that feels smoother and firmer, builds over roughly 4 weeks of consistent daily use. Confusing the two is how people end up disappointed. The glow arrives on day one. The structural change takes a month of showing up.

With both delivery methods understood, the two can now be compared properly, factor by factor.

PDRN Injections vs Topical PDRN Serum: The Honest Head to Head

Effectiveness

Both routes work through the same underlying ingredient, but depth of delivery and scale of intervention are genuinely different. Injections reach the dermis directly, which is why the randomized controlled trial evidence shows measurable change in elasticity, hydration and surface roughness at 12 weeks against placebo. Topical PDRN at 2% is better understood as ongoing renewal, prevention and maintenance rather than acute structural correction, with results supported by supplier-run clinical studies on 2% INJIN PDRN. Keep that attribution distinction in mind when comparing: one body of evidence is independent and peer-reviewed, the other is supplier-generated, and both are legitimate as long as they are labeled honestly.

Cost

Clinic sessions run from the low hundreds to well over a thousand dollars, and a full course lands in the thousands. The PDRN Serum is $18 for 30ml. The gap is enormous, but so is the difference in what is being delivered and by whom.

Accessibility

Injections require a qualified practitioner within reasonable travel distance, appointments you can attend across a 9 to 12 week window, and a geography that supports it. Availability is far better in major metros than in smaller markets. A topical is available from day one with no booking, no travel and no waiting. You can shop the PDRN Serum and start tonight. It is also available on Amazon US.

Comfort

Injections involve needles, and while practitioners often use topical numbing, most people report mild discomfort during treatment. A serum is a painless step in your routine. Some people notice a brief tingling sensation on first application, which settles quickly and is not a sign of irritation.

Downtime

Expect up to 48 hours of redness and mild swelling after an injectable session, which is normal and transient. If you want to understand post-treatment redness and how skin behaves during that window, we have covered it separately. Topical PDRN has no downtime at all.

Safety and oversight

Both routes have good safety profiles when used correctly. Injectables depend heavily on practitioner skill and credentials, and the off-label regulatory status in the US is a legitimate question to raise at consultation. Our topical is formulated for low irritation and daily use, though we always recommend patch testing anything new. If you have not done one before, here is why you need to do a patch test.

Pregnancy and breastfeeding

For any injectable treatment, always consult your healthcare provider first, without exception. The PDRN Serum is confirmed safe during pregnancy and breastfeeding, which is a genuine point of difference and one of the reasons it suits people who have had to pause most of their previous routine.

Vegan credentials

Injectable PDRN used in clinics is typically salmon-derived. Ours is INJIN Vegan PDRN, plant-derived from Artemisia capillaris, with no animal materials involved at any point.

Results timeline

Injections: early visible improvement from around 6 weeks, fuller results at around 12 weeks, across a course of 3 to 4 sessions. Topical: an instant glass skin glow from day one thanks to the emollient blend, with longer-term smoothness and firmness developing from around 4 weeks of consistent use.

Long-term maintenance

Injectable results gradually fade over roughly 6 to 12 months and require top-up sessions to maintain, which is a recurring cost. Topical benefits are maintained for as long as you keep using the product, which is a smaller recurring cost but an ongoing daily commitment.

So which one wins?

Neither, and that is the honest answer rather than a diplomatic one. These are two delivery methods for the same ingredient, operating at different depths, at different intensities, at very different price points, and suiting different lives. An injectable course is a targeted clinical intervention with professional oversight. A daily serum is a sustained habit that compounds quietly over months and years. Comparing them is less like comparing two products and more like comparing a course of physical therapy to a daily walk. Both are legitimate. They are answering different questions.

If you are also weighing PDRN against other advanced actives, we have two companion pieces worth reading: PDRN vs Exosomes compares the two ingredients everyone is currently talking about, and PDRN vs Retinol sets PDRN against the more familiar anti-aging active most people already know.

The right answer depends on your goals, your budget and your life. For a lot of readers, one specific question decides it.

Is PDRN Suitable for Acne-Prone Skin?

Yes, topical PDRN is generally well suited to acne-prone and blemish-prone skin, and the reasoning is straightforward once you look at what the ingredient is and is not.

PDRN is not an exfoliating acid and it is not a retinoid. That distinction matters more than it might sound. If your skin is already dealing with breakouts, and you are already using something drying or turnover-driven to manage them, the last thing you want is another active adding irritation on top. PDRN does not work by increasing cell turnover or dissolving the bonds between surface cells. It is a renewal-supporting ingredient rather than an exfoliating one, which is why it tends to sit comfortably in routines that are already working hard.

The formula itself is built for tolerance. The PDRN Serum is formulated for low irritation and daily AM and PM use, has a pH of 4.0 to 4.5 which sits comfortably within the skin’s own preferred range, is fragrance-free, and is vegan. Fragrance-free is not a small detail for reactive skin, since added fragrance is one of the more common triggers for sensitivity.

Layering it with a blemish routine

This is where it gets genuinely practical, because almost nobody with acne-prone skin is using just one product. The PDRN Serum works alongside salicylic acid, AHAs, Vitamin C and retinol. You do not need to dismantle a routine that is working in order to add it. In practice, that usually means applying PDRN Serum after your cleanser and any water-based treatment step, and before your moisturizer.

The honest caveat

No serum suits every single person, and we are not going to pretend otherwise. If you know your skin runs sensitive, patch test before you commit to full-face application. And if your skin is actively irritated right now, or your barrier is compromised, the priority is calming and rebuilding before you introduce anything new at all. A damaged skin barrierneeds support first, and adding products to inflamed skin rarely goes well regardless of how gentle those products are. In that situation, focus on barrier repair with something like our Bio-Active Ceramide Moisturizer at $22, and add PDRN once things have settled.

For proper guidance on managing breakouts, including what causes them and which actives address what, our acne pillar page is the right place to go. This article is about PDRN specifically, and we would rather point you somewhere thorough than compress a complex subject into three paragraphs.

Having covered suitability, let us get practical about routines.

Which One Is Right for You, and How to Build PDRN Into Your Routine

Who is genuinely better suited to clinic treatments

If you are looking for significant correction of established photoaging, meaningful loss of skin density, or structural laxity that consistent daily skincare has not shifted, injectable PDRN is a reasonable thing to explore. It suits people who have the budget for a multi-session course and the access to a properly qualified practitioner. It also makes sense for anyone already under the care of an aesthetic practitioner, where PDRN can be positioned within a broader treatment plan.

If you go that route, the safety guidance is worth repeating because it genuinely protects you. Only ever be treated by a licensed medical professional or a qualified aesthetic practitioner. Verify their credentials independently rather than taking a website’s word for it. Insist on a proper pre-treatment consultation, not a five minute chat before the needle comes out. Ask directly which product they are using and what its regulatory status is in the US. And be cautious of pricing that looks unusually low, because in aesthetics a bargain is often a signal about the product, the training or both.

Who is better suited to topical PDRN

Topical PDRN makes sense if you want PDRN’s benefits without the cost or the clinical commitment. It suits people in their mid-twenties and up who want to support their skin proactively rather than correctively. It suits sensitive skin, thanks to the low irritation formulation. It suits anyone who is pregnant or breastfeeding, since the PDRN Serum is confirmed safe for both. It suits vegans, given the plant-derived source. It suits the budget-conscious, straightforwardly. And it suits anyone already running other actives who wants a low-irritation daily step that will sit alongside them without conflict.

Can you do both?

Yes, and it is a perfectly reasonable approach. Topical PDRN works well as a daily layer between clinic sessions, keeping something working in the gaps rather than leaving skin untouched for four weeks at a time.

One important caveat. Always check with your practitioner before introducing topical actives around your treatment dates, and follow their specific aftercare protocol to the letter. This matters especially with microneedling, where the skin barrier has been deliberately disrupted and the aftercare window is not the moment to be improvising with new products.

The routine, with the layering order resolved

Apply your exosome serum first, straight after cleansing, then PDRN. That is the order recommended on the Exosome Hydro-Glow Complex page and it matches the INKEY Tip on the PDRN Serum page.

AM routine:

1. Cleanse
2. Exosome Hydro-Glow Complex
3. PDRN Serum
4. Bio-Active Ceramide Moisturizer
5. Finish with a broad-spectrum SPF

PM routine:

1. Double cleanse
2. Exosome Hydro-Glow Complex
3. PDRN Serum
4. Bio-Active Ceramide Moisturizer

The maximum glow pairing

Maximum glow: Apply Exosome Hydro-Glow Complex first, then layer the PDRN Serum over it. The Exosome Hydro-Glow Complex delivers 6-in-1 skin rejuvenation: clinically proven to visibly improve radiance, hydration, tone, firmness, elasticity, and texture. 100% saw more glowing skin, clinically proven,with clinic worthy rejuvenated skin in 14 days. It also helps support natural collagen production and is proven to deliver up to 12-hours of hydration.*

Together they make a straightforward glow boosting pairing.

If you are trying to decide between the two ingredients rather than use both, that is the natural next question, and we have answered it in full in PDRN vs Exosomes. For more background on exosomes generally, start with Exosomes Explained, then plant-derived vs fermentation-derived exosomes if you want to understand sourcing, and 5 Exosome Skincare Myths Debunked for the misconceptions worth clearing up.

Other pairings worth knowing

Barrier support. Follow the PDRN Serum with Bio-Active Ceramide Moisturizer at $22 to seal in hydration and support the skin barrier. If you want to understand why ceramides matter for barrier health, we have covered that too.

Hydration. Apply Hyaluronic Acid Serum to damp skin first, then layer the PDRN Serum over it. Damp application matters, because hyaluronic acid works by holding water and you want to give it water to hold.

Anti-aging pairing. Use PDRN in the morning and a retinoid at night. This keeps the two apart, which reduces the chance of irritation while letting each do its job. Our retinol pillar page covers how to introduce a retinoid properly, and What Not to Mix with Retinol is essential reading before you start combining actives. If you are already using one, Boost Your Retinol Results With Exosome is a useful next step.

Weekly boost. Add the Exosome Boosting Dry Sheet Mask as an optional weekly treatment.

Verified reviewers tend to describe the effect in fairly consistent terms. As Fiona put it: “Love it! Skin feels firmer and smoother.”

A few questions come up again and again, so let us deal with them directly.

Conclusion: The Bottom Line on PDRN Injections vs Topical PDRN

These are two delivery methods for the same ingredient, working at different depths, different intensities and radically different price points. The question was never which one is better in the abstract. It is which one matches what your skin needs, what your budget allows and how much clinical commitment you want to take on.

If you are dealing with established photoaging, meaningful loss of skin density or laxity that daily skincare has not addressed, and you have the access and the budget for a full course, injectable PDRN has a real evidence base behind it. The randomized controlled trial data is genuine and the peer-reviewed literature is growing. Go in with good questions, a qualified practitioner and realistic expectations, and it is a legitimate option.

If what you want is daily renewal, prevention and maintenance, topical PDRN does that job without needles, appointments or four-figure invoices. It is the right fit if you are budget-conscious, vegan, pregnant or breastfeeding, sensitive-skinned, or simply want to start tonight rather than in six weeks when the consultation slot comes up.

The two are not mutually exclusive. Topical PDRN works well as the daily layer between clinic sessions, provided you follow your practitioner’s aftercare advice around treatment dates.

Our position has not changed. Clear guidance, proven ingredients, real results. Effective skincare should be understandable and affordable, and you should never need a translator or a five-figure budget to work out what is actually in a bottle and whether it will do anything. Whichever route you choose, you are working with the same underlying idea: your skin already knows how to renew itself. The question is only ever how you support it, at what depth and at what price.
