Hi! 😊
Yes, Medik8 Crystal Retinal 20 contains vitamin C derivatives, including ethyl ascorbic acid and tetrahexyldecyl ascorbate.
Even if you have used 4% retinol for several years, the strengths cannot be directly compared. Crystal Retinal 20 is the strongest variant in the series, so start with 1-2 evenings per week on dry skin, use a small amount, and only increase when the skin feels comfortable. Feel free to apply moisturizer afterwards, always use sunscreen during the day, and do a patch test before you start ☀️
All the best! 🤍
