Frezyderm Revitalizing Serum is made with natural ingredients such as rose hip oil, shea butter and macadamia nuts. Rose hip oil is rich in antioxidants that help protect the skin from free radicals in the environment while nurturing it with essential fatty acids. Shea butter is high in vitamins A, E and fatty acids that deeply hydrate the skin for a softened supple feel. Macadamia nuts were specifically included for their moisturizing benefits and healing effects on dry or irritated skin.
