Really makes a difference to the tone and brightness of my skin. Looks much clearer. I use this each evening & a red light mask in the mornings. ### ⭐⭐⭐⭐ Great retinol but buy with caution if you have sensitive skin. *by L***! on 9 December 2025* I have used the retinol 3 for a while so decided to upgrade to the 6. Although this works for a lot of people it caused an excema flare up on my face so may be too strong for sensitive skin. ## Frequently Bought Together - Medik8 Crystal Retinal 6 - Age-Defying Retinal Night Serum - Improves Wrinkles & Skin Firmness- 0.06% Retinal Strength - 11x Faster than Retinol - For Regular Vitamin A Users - 30ml - Medik8 Advanced Night Restore - Rejuvenating Multi-Ceramide Night Cream - Moisturiser - Deeply Nourish and Visibly Firm Your Complexion While You Sleep - 50ml - Medik8 Crystal Retinal Ceramide 3 Eye Cream - Anti Ageing & Anti Wrinkle - Smooth & Lift Eye Cream - 0.03% Retinal Strength - 11x Faster than Retinol - For New Vitamin A Users - 15ml --- ## 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.com.ar/products/404998468-crystal-retinal-6-age-defying-serum-0-06-retinal-strength](https://www.desertcart.com.ar/products/404998468-crystal-retinal-6-age-defying-serum-0-06-retinal-strength) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-04*
