Take the next step up from standard Retinol with the new Crystal Retinal 1 from Medik8. This innovative overnight treatment contains a specialist crystal-encapsulated form of 0.01% 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. This very mild concentration is perfect for those new to the ingredient and anyone with sensitive skin. It effectively boosts collagen production, smoothes uneven texture and contains natural antibacterial properties to help minimise breakouts. Added Hyaluronic Acid and Vitamin E hydrate and repair the skin, while specialist time-release technology ensure skin experiences minimal irritation. Suitable for all 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.Mild concentration of RetinaldehydeWorks 11 times faster than standard RetinolTo be applied in the eveningSuitable for those with sensitive skin
