Vitamin C for Skin: Protecting Against Premature Ageing

Vitamin C is one of the most valuable antioxidants in skincare — a daytime defender that helps protect skin from the environmental stress that drives premature ageing, while brightening the look of tone.

What vitamin C does

As a topical antioxidant, vitamin C helps neutralise free radicals generated by UV exposure and pollution. It's also well studied for supporting the skin's collagen and for helping to visibly even tone and fade the look of dark spots and uneven tone over time.

Why antioxidants matter

Free radicals from sun and pollution damage collagen and accelerate visible ageing. Antioxidants like vitamin C and vitamin E work as a defensive layer, mopping up that damage before it accumulates — which is why they belong in every morning routine, underneath SPF.

How to use it

• Apply in the morning, after cleansing and before moisturiser.
• Layer under SPF — vitamin C complements, but does not replace, sunscreen.
• Be consistent: brightening benefits build with daily use.
