SkinCeuticals - C E Ferulic

SkinCeuticals C E Ferulic is a daytime antioxidant serum that helps defend skin against the free radicals generated by UV exposure, pollution, and ozone. It combines 15% pure vitamin C (L-ascorbic acid) with 1% vitamin E and 0.5% ferulic acid, a pairing developed from antioxidant research at Duke University.

Used each morning under sunscreen, it works alongside your SPF rather than replacing it. Sunscreen filters UV light, while antioxidants help neutralize the oxidative damage that gets through. With consistent use, skin looks brighter and more even, and the appearance of fine lines and lost firmness softens.

The serum absorbs quickly, layers cleanly under moisturizer and sunscreen, and remains effective in the skin for a minimum of 72 hours after application. It is fragrance-free, dye-free, and paraben-free, and is formulated for normal, dry, and sensitive skin.

1. Cleanse and dry your skin completely. Vitamin C absorbs best on a dry surface.
2. In the morning, apply 4 to 5 drops to your face, neck, and chest.
3. Press the serum in with your fingertips rather than rubbing, and let it absorb for about 60 seconds.
4. Follow with your moisturizer, then a broad spectrum sunscreen.
5. Use once each morning. If your skin is new to vitamin C, start every other morning and build up.

Store the bottle upright, away from heat and direct light. A gradual shift toward amber is normal. Discard the serum if it turns dark brown.

15% L-Ascorbic Acid (Vitamin C): the pure, bioavailable form of vitamin C. Helps neutralize free radicals and supports the skin's natural collagen production.

1% Alpha Tocopherol (Vitamin E): a lipid-soluble antioxidant that helps protect cell membranes and works synergistically with vitamin C.

0.5% Ferulic Acid: a plant-derived antioxidant that stabilizes the formula and enhances the photoprotection of the vitamin C and vitamin E pairing.

Our providers reach for C E Ferulic when a patient wants one antioxidant serum to anchor a morning routine, particularly for normal, dry, or sensitive skin. It is among the most studied vitamin C formulas in medical-grade skincare, and the reason is stability: the low pH and the vitamin E and ferulic acid pairing keep L-ascorbic acid active on the skin rather than oxidizing in the bottle.

A few practical points. Vitamin C does not replace sun protection, so continue using broad spectrum SPF every day. Brief tingling on application is common and usually settles within a minute. If your skin is reactive, or you are also using a retinoid, alternate mornings at first. If your skin is oily or acne-prone, Silymarin CF or Phloretin CF may suit you better. If you are preparing for or recovering from an in-office treatment, ask your provider when to restart vitamin C. You can order this here without an appointment, and we ship nationwide.
