Medik8 Crystal Retinal 6 Serum 30ml

The Medik8 Crystal Retinal 6 Serum is a targeted anti-ageing treatment formulated with 0.06% stabilised retinaldehyde, a fast-acting form of vitamin A. This advanced serum is designed to address multiple signs of skin ageing through its potent renewing and skin-smoothing properties. It forms part of Medik8's innovative Crystal Retinal collection, which offers a graduated ladder of five strengths to allow users to build tolerance and achieve optimal results at different stages of their skincare journey. Key features include encapsulation technology that protects the retinaldehyde, ensuring it remains stable and effective while being gradually released into the skin. The formula is enriched with complementary ingredients like hyaluronic acid for hydration, glycerin to support the skin's moisture barrier, and vitamin E for antioxidant protection. This combination works to diminish the appearance of fine lines, uneven texture, dullness, and discolouration, promoting the look of improved elasticity and bounce. The serum is dermatologist-recommended and based on clinical testing that demonstrated measurable improvements in skin appearance. This particular strength (Crystal Retinal 6) is best suited to individuals who already have some experience using retinaldehyde or vitamin A derivatives in their skincare routine. It offers a middle-ground potency within the range, making it appropriate for those looking to step up from lower concentrations. The 30ml bottle provides a practical supply for consistent nightly use over several weeks, fitting seamlessly into an evening skincare regimen focused on anti-ageing and skin renewal.
