What Does Vitamin C Do for Your Skin? The Complete Guide

Vitamin C is one of the most talked about ingredients in skincare, and for good reason. It has strong scientific evidence behind it and delivers multiple benefits that are particularly valuable for women with Melanated skin dealing with hyperpigmentation, dark spots or uneven skin tone.

What Does Vitamin C Do for Your Skin?

Brightens and Evens Skin Tone

Vitamin C inhibits tyrosinase, the enzyme responsible for converting amino acids into melanin. By slowing this process, it helps to fade existing dark spots and prevent new ones from forming. Over time it visibly brightens the complexion and evens out skin tone.

Neutralises Free Radical Damage

Vitamin C is a powerful antioxidant. It neutralises free radicals generated by UV exposure, pollution and stress that damage skin cells and accelerate the formation of dark spots.

Boosts Collagen Production

Vitamin C is essential for collagen synthesis, keeping skin firm, plump and smooth. It helps to stimulate new collagen, improving skin texture and keeping skin looking youthful.

Enhances SPF Protection

When used alongside SPF, Vitamin C provides an additional layer of antioxidant protection against UV damage, making your morning routine significantly more effective at preventing new pigmentation.

How Vitamin C Compares to Other Brightening Ingredients

Vitamin C vs Alpha-Arbutin: Alpha-Arbutin works at the melanin production stage while Vitamin C works as an antioxidant and brightener. They address different pathways and work very well together. Use Vitamin C in the morning and Alpha-Arbutin via our Active Fading Serum in the evening.
Vitamin C vs Kojic Acid: Kojic Acid is a stronger melanin inhibitor for stubborn deep spots, while Vitamin C provides broader antioxidant and brightening benefits. Combining them is often more effective than either alone.
Vitamin C vs Niacinamide: Niacinamide is more hydrating and barrier-supportive, while Vitamin C is more potent as a brightener. They can be used together at different times of day.
Vitamin C vs Retinol: Retinol accelerates cell turnover and is used in the evening, while Vitamin C is used in the morning and is more suitable for daily long-term use.

The Best Form of Vitamin C for Melanated Skin

The most potent and well-researched form is L-Ascorbic Acid. Our Vitamin C Glow Serum contains 15% L-Ascorbic Acid paired with Hyaluronic Acid to deliver brightening and hydration together.
