How It Works
Clinical-grade vitamin A, otherwise known as retinoic acid, is an exceptionally powerful skincare ingredient for youthful-looking skin. Highly potent and wildy efficacious, it is able to trigger cellular regeneration and collagen production to fight all visible signs of ageing. Retinoic acid is only available with a prescription, but vitamin A is available over the counter in the form of retinol skincare products.
Crystal Retinal requires just one conversion to retinoic acid. This means that it is able to produce results comparable to retinoic acid up to 11 times faster than classic forms of retinol. The advanced active is carefully encapsulated in a crystal structure that is broken down by the skin’s natural enzymes when topically applied. This ensures maximum stability and absorption while allowing the vitamin A active to be released gradually into the skin while you sleep for minimal irritation.

Combined with hydrating hyaluronic acid and skin-soothing vitamin E, Crystal Retinal targets fine lines and wrinkles for smooth and visibly youthful skin. Unlike other forms of vitamin A, retinaldehyde boasts direct, powerful antibacterial properties. This allows it to target acne-causing bacteria; promoting a healthy, visibly clear complexion.
How To Use
Use in the evening. First cleanse, then apply Crystal Retinal over face and neck. Allow to absorb then follow with a moisturiser.
Crystal Retinal application should be phased in gradually. Use twice a week for the first 2 weeks, every other night for the next 2 weeks, then every night.
Patch testing prior to use is advised. Refer to medik8.co/patch for an in-depth guide to patch testing.
With a unique ability to attract and retain more than 1,000 times its own weight in water, hyaluronic acid draws moisture from the surrounding atmosphere into the skin, leaving the complexion feeling both nourished and supple.
An oil-soluble antioxidant, vitamin E can quench free radicals on the skin while stabilising retinaldehyde for optimal power.
As a natural humectant, glycerin traps water within the skin to leave it hydrated and comfortable.Full Ingredients
