Studies have shown that a diet rich in Vitamin C can keep illnesses at bay. Now, research reveals that this antioxidant may also save your skin. Ester-C® is a more stable form of Vitamin C that promotes collagen production and fends against free radical damage caused by sun, stress, and the harsh environment. JASON uses the powerful antioxidant properties of Vitamin C in a potent Ester-C® complex that penetrates deep into the skin to prevent fine lines and wrinkles, inhibit melanin production and aid in the repair of sun damaged skin.
