Vitamin A taken to the next level. Crystal Retinal™ is an advanced anti-ageing serum formulated with stabilised retinaldehyde (retinal), a next-generation form of vitamin A. Not to be confused with ""retinol"" (the classic form), retinaldehyde has been desmonstrated in multiple scientific studies to be more effective than retinol, but without added irritation.
Retinal can deliver results comparable to clinical-grade vitamin A up to 11 times faster than retinol. Stabilised using patented crystal encapsulation and a patent pending carrot seed complex, this innovative overnight serum visibly minimises fine lines and wrinkles; firming and plumping the complexion to resurface skin texture and create an overall youthful appearance. The vitamin A is released gradually into the skin during the night, for minimal irritation.
Also featuring hyaluronic acid and glycerin to draw moisture to every level of the skin, leaving it hydrated and visibly supple.
As well as addressing signs of ageing, Crystal Retinal helps to reduce blemish-causing bacteria, visibly improving the clarity of the complexion.
Medik8 offer progressive concentrations of Crystal Retinal products which form the Medik8 Crystal Retinal Ladder. Crystal Retinal 10, containing 0.1% retinaldehyde, is recommended for those who have comfortably used Crystal Retinal 6.
