L-Ascorbic Acid (Vitamin C)

L-ASCORBIC ACID: THE GOLD STANDARD IN ENVIRONMENTAL PROTECTION

L-ascorbic acid is the purest form of vitamin C, and it has been proven to provide powerful antioxidant benefits that help protect the skin from environmental damage while improving the visible signs of aging.

WHAT IS VITAMIN C?

The purest form of vitamin C is L-ascorbic acid, and research has shown that this ingredient provides the greatest level of protection against free-radical damage caused by environmental assaults like UV rays, infrared radiation (IRA), pollution, and lifestyle factors, while improving visible signs of aging.

Vitamin C Explained

What are the benefits of 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.

Why is vitamin C important?

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.

Is vitamin C good for your face?

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.

Is vitamin C good for oily skin?

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.

Is vitamin C good for sensitive skin?

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+.
