Vitamin A taken to new age-defying heights. Crystal Retinal™ is a cult advanced anti-ageing serum crafted with stabilised retinaldehyde (retinal), a next-generation form of vitamin A. Not to be confused with classic form "retinol", retinaldehyde has been demonstrated in multiple scientific studies to harness improved efficacy compared to retinol, but without any added irritation.
Delivering results comparable to clinical-grade vitamin A, retinal is proven to work up to 11 times faster than retinol. Stabilised using patented crystal encapsulation and a patent pending carrot seed complex, this results-focussed overnight serum visibly minimises fine lines and wrinkles; helping to resurface skin texture and create an overall youthful complexion. The vitamin A is released gradually into the skin throughout the night, for minimal irritation.
Featuring hyaluronic acid and glycerin to draw moisture to every level of the skin, infusing skin with hydration and leaving it visibly supple.
Not only designed to target signs of ageing, Crystal Retinal helps to reduce blemish-causing bacteria, visibly improving skin clarity.
Medik8 offer progressive concentrations of Crystal Retinal products which form the Medik8 Crystal Retinal Ladder. Crystal Retinal 1, containing 0.01% retinaldehyde, is recommended as a starting point for those with more sensitive skin before moving to Crystal Retinal 3.
