Crystal Retinal 1

HOW IT WORKS. 
Clinical grade Vitamin A, also known as retinoic acid, is an exceptionally powerful skin rejuvenation ingredient. It has a high potential to activate cellular regeneration and collagen production, and fights all visible signs of aging. Retinoic acid is available only by prescription, while vitamin A is freely available in the form of retinol-based skin care products.

Retinol works in a similar way to retinoic acid, but it must first be converted to retinaldehyde and then to retinoic acid. The skin can only utilize retinoic acid. Crystal Retinal 6 Serum contains retinaldehyde, which is only one step away from retinoic acid. Therefore, retinaldehyde delivers the same results as retinoic acid, but 11 times faster than classic forms of retinol1. The advanced active ingredient is encapsulated in a crystalline structure that is broken down by natural skin enzymes when applied topically. This ensures maximum stability and absorption, as well as a gradual release of vitamin A into the skin while you sleep for minimal irritation. Crystal Retinal contains moisturizing hyaluronic acid and soothing vitamin E to smooth fine lines and wrinkles, visibly smooth and rejuvenate the skin. Unlike other forms of vitamin A, retinaldehyde has a direct antibacterial effect: it reduces the number of bacteria that cause acne, visibly improving the appearance of the skin.
