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 0.05% 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.

  • What it does: 0.05% 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**.

    Do not seem to get much in tube

    Hi, thank you for flagging this - we're sorry it feels like you're not getting much product in the tube! A couple of quick tips: a pea-sized amount is all you need per use, so Advanced Retinal should last longer than you might expect. And when you get toward the end, cutting the tube open (like another customer cleverly did!) can help you access a few extra days' worth that gets trapped in the design.
    If you still feel the fill level is off, please reach out to our Customer Experience Team at help@theinkeylist.com — they'd be happy to take a look. 💙
