Medik8 Crystal Retinal 20 Serum 30ml

The Medik8 Crystal Retinal 20 Serum is a targeted night treatment serum formulated with a 0.2% concentration of retinaldehyde, a highly effective form of vitamin A. Designed for experienced users, this advanced formula works overnight to address multiple visible signs of skin ageing. Its primary function is to improve skin texture, firmness, and overall tone through consistent nightly application. The serum's key active ingredient, retinaldehyde, is clinically proven to help minimise the appearance of fine lines, pigmentation, and textural irregularities. To support skin tolerance and hydration, the formula is blended with hyaluronic acid, glycerin, and vitamin E. These complementary ingredients help counteract potential dryness and sensitivity. Medik8 employs a patented stability system within the product to ensure the retinaldehyde remains potent and effective throughout its use, maximising the benefits for the user. This product is specifically recommended for those who have already built up tolerance to lower-strength retinoids, having comfortably used two tubes of the Crystal Retinal 10 formulation. It fits into an evening skincare routine after cleansing and before moisturising. As the strongest option in Medik8's five-step Crystal Retinal ladder, it represents a professional-grade treatment for individuals seeking significant improvements in skin clarity and firmness without resorting to prescription-only alternatives.
