Discover a younger-looking complexion with Crystal Retinal 1.
Featuring retinaldehyde (retinal), a next-generation form of vitamin A which is not to be mistaken for the classic form of vitamin A, retinol. In numerous studies, retinal has been demonstrated to be more effective and 11x faster-working than retinol, without any additional irritation.[1,2,3]
The hydrating overnight serum-cream visibly addresses signs of aging; improving the aappearance of wrinkles, texture and tone. Potency and optimum power is ensured through a double-layered stabilization system, which includes a crystal encapsulation that releases vitamin A gradually throughout the night, to protect the skin from becoming overwhelmed at any point. Hyaluronic acid and glycerin also feature to moisturize and hydrate skin, minimizing any dryness. The complexion is left visibly smooth and supple. Crystal Retinal is available in a series of progressive strengths. Crystal Retinal 1 (0.01% retinal) is the perfect starting point for sensitive skins before moving up to Crystal Retinal 3. Medik8 recommend a simple, effective skincare strategy of using vitamin C and sunscreen in the morning and vitamin A at night.
This strategy is called: CSA.
