Cetaphil Vitamin C Serum

Cetaphil Vitamin C Serum is a brightening antioxidant serum formulated for sensitive skin — a combination that is genuinely hard to find. This 1 oz (30 ml) bottle uses a stable form of vitamin C to visibly brighten the complexion, improve the look of dark spots and uneven tone, and defend the skin against the environmental free radicals that accelerate visible ageing. Vitamin C also supports the skin's natural firmness over time, so skin looks smoother and more resilient with consistent use. Where most vitamin C serums rely on high-strength L-ascorbic acid that stings and flushes reactive skin, this is built to Cetaphil's mildness standards and paired with hydrating, soothing ingredients — so you can use it daily without irritation. The lightweight texture absorbs quickly with no tackiness and layers cleanly under moisturiser, sunscreen or makeup. Fragrance-free, non-comedogenic and dermatologist tested. Apply a few drops to clean skin each morning, then follow with a moisturiser and broad-spectrum sunscreen — vitamin C and daily SPF work best as a pair.
