It's noticeably thicker than 10, and also makes your face shockingly yellow (this is a sign of good quality retinol, apparently), a little sticky on the pillow. But despite its strength, I've had no irritation, using once or twice a week, alternating with 10. I always us a peptide first (Medik8 or Vichy89), and if I notice any dry or tight patches, I revert to 6 for a few days.I've used retinol for so long I wouldn't have a skin 'transformation', but Im in no doubt that retinol has been keeping my skin texture in good nik, and this is by far one of the best I've used. ### ⭐⭐⭐⭐⭐ The Jury is out *by on Reviewed in the United Kingdom 1 April 2026* It cost more than I usually pay but thought I would give it a try. To be fair I haven't used it religiously or regularly. It didn't cause any rash or burning. I can't see myself purchasing it again, probably hype. I read that retinal content has to be very high to be effective and these creams are only available on prescription, used for burns victims etc. ### ⭐⭐⭐⭐⭐ Need more time for results *by on Reviewed in the United Kingdom 29 September 2025* I've only just started using this. Need more time for results I think it's helping though ## Frequently Bought Together - Medik8 Crystal Retinal 20 - Age-Defying Retinal Night Serum - Improves Wrinkles & Skin Firmness- 0.2% Retinal Strength - 11x Faster than Retinol - For Highly Experienced Vitamin A Users - 30ml - Medik8 C-Tetra Luxe - Lipid 14% Vitamin C Enhanced Radiance Serum -Smooths Fine Lines & Uneven Tone - Antioxidant & Nourishing - Dull, Dry Skin Types - 30ml - Medik8 Advanced Night Restore - Rejuvenating Multi-Ceramide Night Cream - Moisturiser - Deeply Nourish and Visibly Firm Your Complexion While You Sleep - 50ml --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/675313545-crystal-retinal-20-age-defying-serum-0-2-retinal-strength](https://www.desertcart.sg/products/675313545-crystal-retinal-20-age-defying-serum-0-2-retinal-strength) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-08-17*
