What should you know about CE Ferulic vitamin C?

Vitamin C serum commonly contains L-ascorbic acid, an antioxidant used to help address dull appearance and uneven-looking tone. Ferulic acid is often paired with antioxidant ingredients in an effort to support formula stability. A topical serum is cosmetic skincare, not a treatment for melanoma, infection or a rapidly changing pigmented mark. Results vary with the formula, storage, skin sensitivity and the concern being treated.

Apply a small amount to clean, dry skin as directed on the product label, then use moisturiser if needed. Start on an occasional schedule if your skin is reactive, and avoid applying it to broken skin. Store the bottle as instructed; changes in colour, smell or texture can indicate that the formula has degraded. Daily broad-spectrum sunscreen is still needed because vitamin C does not replace ultraviolet protection. See Vitamin C Serum for more about this ingredient category.

Stop using the serum and seek medical advice if burning, swelling, hives, blistering or a persistent rash develops. Arrange a skin examination for a new or changing dark spot rather than trying to treat it with a brightening product.

Ask whether the ingredient list suits your skin condition, how to combine it with prescribed products, and whether a persistent pigment change needs diagnosis before cosmetic treatment.
