BENEFITS Retinaldehyde is the star of Crystal Retinal; a next-generation form of vitamin A that has been shown to deliver results up to 11 times faster than retinol [1] . Yes, it's retinAL, faster-acting than retinOL, the classic form of vitamin A. RESULTS Crystal Retinal, uniquely stabilized for optimal potency, is clinically proven to deliver incredible, age-defying results in a single tube—think visibly brighter, firmer, and smoother skin. KEY INGREDIENTS Encapsulated retinaldehyde, patent-pending stabilization system, hyaluronic acid, vitamin E and glycerin How to use How to Apply Use at night. First, cleanse and apply two pumps of Crystal Retinal to your face and neck. Allow to absorb and follow with a moisturizer. We recommend Advanced Night Restore, designed to be used after vitamin A.
