Retinoid C Serum combines two powerful active ingredients: Retinoid HPR (retinoic acid derivative) and stabilized form of Vitamin C, thus offering multiple actions without irritating the epidermis. Reduces fine lines, wrinkles, neutralizes the action of free radicals and protects the skin from oxidative stress. In addition, it improves the roughness, imperfections and texture of the epidermis. Skin discolorations and age spots are reduced, delivering a uniform, luminous and shiny appearance to the epidermis.
