What you get: An acne treatment serum formulated with 2% Salicylic Acid (BHA) to penetrate deep into pores, clearing existing acne while preventing new breakouts, plus 1% Hyaluronic Acid to maintain skin hydration during treatment.


Why it works: 2% Salicylic Acid (BHA) is the gold standard for acne treatment, working inside pores to dissolve the debris that causes acne, whiteheads, and blackheads. 1% Hyaluronic Acid ensures your skin stays hydrated throughout the acne-clearing process, preventing over-drying.


How it feels: Lightweight, non-greasy serum that absorbs quickly without leaving residue. An effective acne treatment that works gently on acne-prone skin, leaving it feeling clean, balanced, and comfortable


When to use: Apply to cleansed skin morning and/or evening as your acne treatment step. Use 1-2 drops, gently patting into face and neck area. Follow with your preferred serums and moisturizer. Always apply broad-spectrum SPF as the final step in your AM routine

Suitable for:

  • Normal skin
  • Oily skin
  • Combination skin
  • Pregnancy & breastfeeding

Targets:

  • Blemishes & congestion
  • Blackheads
  • Excess oil

Understanding Beta Hydroxy Acids

What makes BHA special? Unlike AHAs that work on the skin's surface, Beta Hydroxy Acid (Salicylic Acid) is oil-soluble, allowing it to penetrate into pores and work from within. 2% Salicylic Acid is the optimal concentration for effective exfoliation without irritation. Higher concentrations are typically reserved for professional treatments.

Why We Added Hyaluronic Acid 1% low-molecular-weight Hyaluronic Acid prevents the dryness often associated with exfoliating acids, making this suitable for daily use.

Perfect Partners:

  • Salicylic Acid Cleanser (double the pore-clearing power)

  • Omega Water Cream (oil-free moisture for acne-prone skin)

  • Niacinamide Serum (reduces oil production and calms irritation)

    Ok so far

    I’ve not been using this long so can’t really comment on results. It is easy to use and hasn’t caused a reaction with my sensitive skin. I’ll continue to use as part of my evening skin care routine.

    Excellent

    I have sensitive skin which became a bit congested over the summer. I was wary trying this but I have to say I had no reaction or sensitivity and my skin is becoming so much better.

    Hi Tann, thank you for your honest feedback - we're sorry this wasn't the result you were hoping for.
    This may actually be purging. BHA works deep inside the pore to clear congestion, which can bring blockages that were already forming to the surface faster than usual - so they appear as spots before they clear. It typically settles within 4–6 weeks, and skin is usually clearer on the other side of it.
    That said, every skin is different - if this feels more like irritation than purging, please stop using it and reach out to our Customer Experience Team on help@theinkeylist.com. They'd love to help you figure out what's going on and find the best route to tackling blackheads. 💙
