  • 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 or greasiness. Users report smoother skin texture, reduced fine lines, and brighter, more even complexion within weeks of use. Many mention it works well for experienced retinoid users, causing minimal irritation compared to other products. Customers appreciate that it layers easily in nighttime routines and doesn't cause burning or excessive dryness. Several note improvements in dark spots and pore appearance. The yellow tint disappears upon application, though some initially found it concerning. Most users experienced little to no irritation, making it suitable for sensitive skin types.

    Waking up to better looking skin? Yes, please. The Inkey List Advanced Retinal Serum, 15 ml, targets various signs we see as we age. I have been using retinol products for some time, so my skin did well with this product and I am seeing overall clarity in my skin using this.

    From the first few uses, I noticed how comfortably this serum sat on my skin. it absorbs fast and doesn’t leave any tacky feeling. After sticking with it for a bit, my skin started to look more refined, and the fine lines around the corner of my eyes looked a little softer. I like that it never caused burning or tightness for me, which made it really easy to keep in my nightly routine. Overall, it’s been a simple, effective way to get brighter, smoother-looking skin.

    After 2 weeks, I am starting to see visible results. My dark spots are starting to disappear and my fine lines are a little smoother. It definitely works! Can’t wait to keep using and seeing more results for the upcoming weeks.
