Vitamin C is a globally cherished nutrient acclaimed for its remarkable antioxidant, skin-brightening and anti-aging properties. There are two forms of Vitamin C:

C-Ester (ascorbyl palmitate) is a lipid-soluble, stable form of it that exhibits greater antioxidant activity than the water-soluble form, ascorbic acid. The lipid solubility enables penetration into cell membranes for strengthening benefits. Compared with ascorbic acid, C-Ester delivers eight times higher levels of Vitamin C activity and has the ability to recycle other antioxidants such as Vitamin E.

Ascorbic acid is water soluble and can be more irritating to the skin. It also oxidizes more quickly than stable C-Ester.

Why it’s important to maximize Vitamin C activity

It has been shown to support collagen health. Collagen is responsible for skin resilience and firmness. When collagen breaks down, fine lines, wrinkles and sagging skin become visible. Research has demonstrated that Vitamin C can actually help stimulate collagen to restore skin’s youthful resilience, texture and firmness, thereby addressing more advanced signs of skin aging.

Vitamin C has also been shown to brighten skin, making it an excellent nutrient for age and dark spots, uneven skin tone, discoloration and sun damage. Research shows that Stay-C 50® inhibits the formation of melanin (dark pigment), and reduces the look of facial spots, promoting more even tone and a brighter complexion.

Additionally, it has been shown to protect against UV-induced damage and improve the appearance of photo-damaged skin. Research shows topical Vitamin C on UV-damaged skin improves uneven pigmentation, tactile roughness and wrinkles. Vitamin C offers excellent added protection as well as a recovery solution for environmentally damaged skin. (Find Vitamin C in Antioxidant Natural Sunscreen SPF 30)
