Crystal Retinal
Crystal Retinal is our ‘everyone’ vitamin A. It is renowned for its universal hydrating texture and low-irritation potential, while delivering profound, proven age-defying results.
Extremely sensitive skins should start low on Crystal Retinal 1 (0.01% retinal), with Crystal Retinal 3 (0.03%) best for sensitive skins or for those nervous about using retinal. Most people can start on Crystal Retinal 6 (0.06%) and gradually move up to Crystal Retinal 10 (0.1%) & 20 (0.2%) for clinical-strength results.
