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. Retinol has similar effects to retinoic acid, however it must first be converted to retinaldehyde and then to retinoic acid to be used by the skin.

Crafted with retinaldehyde, 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.
