Take your skincare to the highest level with Medik8 Crystal Retinal 24 — an expert-strength vitamin A night serum designed to visibly reduce deep wrinkles, improve firmness, and dramatically refine skin texture.
Powered by retinaldehyde (retinal), this next-generation form of vitamin A works up to 11x faster than traditional retinol, delivering faster, more visible results without unnecessary irritation. Retinal requires only one conversion step to become retinoic acid in the skin, making it significantly more effective than standard retinol.
Not suitable for beginners to vitamin A. This formula is designed for experienced users upgrading from Crystal Retinal 10 or equivalent.
Start gradually if moving up in strength — begin 2–3 nights per week and increase as tolerated.
