Vitamin C, Decoded: Brighter, Healthier-Looking Skin
If we had to pick one daytime active for almost everyone, vitamin C would be near the top of the list. It brightens, supports collagen, and adds a layer of antioxidant defence that works beautifully alongside your sunscreen. Here's how to make the most of it.
What vitamin C does for your skin
Vitamin C is a powerhouse antioxidant. During the day, your skin faces UV and environmental stress that generate free radicals; vitamin C helps neutralise them, which supports a brighter, more even and more resilient complexion over time. It also plays a role in healthy collagen, which is why it's a long-term friend to firmness as well as glow.
The quick version
- Best for: dullness, uneven tone, early ageing, and anyone wanting daytime antioxidant support.
- When: mornings, under sunscreen, is the classic pairing.
- Pair with: SPF (they make each other better) and hyaluronic acid for comfort.
- Storage matters: keep it cool and capped; pure vitamin C oxidises with light and air.
How to use it
Apply vitamin C to clean skin in the morning, then layer your moisturiser and finish with sunscreen. It's the natural partner to SPF: your sunscreen blocks much of the UV, and vitamin C mops up the stress that gets through. If you're new to it, start every other day and build up. And do keep an eye on colour, a serum that has turned deep brown has likely oxidised and lost potency.

Frequently asked questions
Can I use vitamin C with retinol?
Yes, though many people prefer vitamin C in the morning and retinoids at night. If you use both at night, introduce them gradually to keep skin comfortable.
Will it irritate sensitive skin?
Higher-strength pure vitamin C can tingle. Gentler derivatives and cream formats are kinder, start slowly and build up.
Does vitamin C replace sunscreen?
No. It supports your sunscreen but never replaces it. The two are a team.
