What you get: A high-strength Retinal serum, clinically proven to target all 5 visible signs of aging, without irritation - smoothing deep wrinkles, fading dark spots, visibly firming and lifting while boosting skin’s luminosity. Perfect for experienced retinoid users ready to upgrade their anti-aging skincare routine.

Why it works: Formulated with 0.2% encapsulated Retinaldehyde, proven to work 11x faster than standard Retinol***, to accelerate cell turnover, promote collagen production and improve skin elasticity. Enhanced with 2% Sirtalice to visibly lift, tighten and smooth skin in as little as 30 minutes****. Unlike standard retinol serums that require multiple conversion steps, our retinaldehyde formula converts directly to retinoic acid in just one step - delivering faster, more effective anti-aging results.

How it feels: Lightweight, hydrating and fast-absorbing. Skin feels instantly nourished, never drying.

When to use: PM only, 2-3 nights a week to start. Increase frequency as your skin builds tolerance. Always follow with moisturizer and use SPF the next morning.

Advanced Retinal Technology: The Next Level Beyond Retinol

Retinoids are the gold-standard for skin longevity - helping improve the look of wrinkles, dark spots and loss of firmness. This Advanced Retinal Serum is for experienced retinol users who want to level up results, without irritation.

  • Why it’s different: Retinal converts to active retinoic acid in one step, so it works 11x faster than standard retinol***. The formula pairs long-term skin renewal with instant firming.

  • What it does: 0.2% encapsulated retinal smooths wrinkles, refines texture and evens tone over time, while 2% Sirtalice™ delivers visible, surface-level firming in as little as 30 minutes**.

  • The results? Skin looks smoother, firmer, and brighter - from 1 week*

Reviews Summary
Customers say this retinal serum has a lightweight, creamy texture that absorbs quickly without leaving residue. Many report smoother, brighter skin with reduced fine lines and dark spots after consistent use. Users appreciate its gentleness for sensitive skin, with minimal irritation compared to other retinal products. The yellow color is frequently mentioned but doesn't stain when applied properly. Most start with 2-3 times weekly use. Common feedback includes improved skin texture, evenness, and a healthy glow. Some note it takes several weeks to see results, while others report changes within days. The price point receives praise for effectiveness.

    Excellent Retinal Serum!

    I have used a number of Retinal Serums and I love this one. I find it does the job and it is much less expensive than the other brands. Since trying out the newest products Inkey List has added to its lineup, my skin feels smoother, and has an improved appearance. I must say, I am more than pleased with the outcome.
