L-Ascorbic Acid (Vitamin C)

Vitamin C in the form of L-ascorbic acid is a powerful antioxidant that helps shield the skin from free-radical damage caused by environmental aggressors such as UV rays, infrared radiation (IR-A), pollution, and lifestyle factors. Vitamin C has also been shown to provide improvement in visible signs of aging like wrinkles, skin laxity, and skin discoloration.

All of SkinCeuticals’ topical vitamin C serums feature L-ascorbic acid, but each formula is tailored for specific skin types and concerns with the addition of other antioxidants. SkinCeuticals currently offers topical vitamin C antioxidants for normal-to-dry and normal-to-oily, and sensitive skin types.

L-ascorbic acid (pure vitamin C) helps protect the skin from free radical damage to improve visible signs of aging. In addition to creating skin-damaging free radicals, environmental factors such as UVA/UVB rays and pollution can deplete the skin’s natural antioxidant levels. Supplementing the skin with a topical vitamin C serum helps replenish skin’s antioxidants , in turn enhancing its defenses against these aggressors.

Vitamin C is an extremely beneficial ingredient for the face because it helps protect against the environmental damage that contributes to premature skin aging while improving the appearance of age-related changes that have already become visible. For optimal results, it’s best to use a topical vitamin C antioxidant serum in conjunction with a broad-spectrum daily sunscreen for the highest level of environmental protection.

Vitamin C is appropriate for all skin types, as long as you choose the proper formulation; oil-free serums are ideal for oily skin. SkinCeuticals Phloretin CF was formulated to improve fine lines and uneven skin tone in normal-to-oily and combination skin types.

SkinCeuticals also offers Silymarin CF, a topical vitamin C antioxidant formulated for oily and blemish-prone skin. Shown to reduce oil oxidation that can create a favorable environment for blemish formation, this first-of-its kind antioxidant serum provides environmental protection while helping to reduce oiliness, refine skin texture, and maintain a clear complexion.

Yes. When using a SkinCeuticals vitamin C serum mild tingling or stinging upon application is normal, but those with especially sensitive skin who are new to vitamin C may want to start with a lower concentration of L-ascorbic acid, such as Serum 10 AOX+.
