As seen on ITV’s This Morning! Wake up to beautiful, radiant skin every day with Medik8’s exciting new Crystal Retinal 10 serum. This innovative formula contains the maximum concentration of a specialist crystal-encapsulated form of 0.1% Retinaldehyde, which is quicker and easier for the skin to convert into Retinoic Acid, getting to work up to 11 times faster than standard Retinol. It effectively boosts collagen production, smoothes uneven texture and contains natural antibacterial properties to help clear up blemishes. Added hydrators including Hyaluronic Acid, Glycerin and Vitamin E hydrate and repair the skin, while specialist time-release technology ensure skin experiences minimal irritation. In just four weeks, users can expect a brighter, firmer, smoother and more youthful-looking complexion. Suitable for most skin types, massage a small amount into cleansed skin in the evening twice a week. Follow with a moisturiser for best results. After two weeks, gradually increase usage until it is applied nightly. Always apply a sunscreen during the day when using this product.Works up to 11 times faster than standard RetinolMaximum strength formulaPlumps, smoothes and brightensTo be used in the evening
