C25 plays a significant role in anti-oxidative skincare. Vitamin C is one of the most researched antioxidants for the skin—it helps neutralise free radicals, supports collagen synthesis and inhibits pigmentation processes. The formulation with 25 % vitamin C, plus vitamin A derivatives and polyphenols, makes C25 particularly effective for revitalising dull, uneven-toned or photo-aged skin.

How to apply

If layering other products, apply C25 after cleansing/toning and before moisturiser. Avoid in pregnancy or breastfeeding unless advised by a professional (due to vitamin A ester content). Start gradually if skin is sensitive.
