Vitamin C Serum: Everything You Need to Know

Vitamin C is a skincare staple for good reason: as a topical antioxidant it defends against daily environmental damage while helping to brighten and even the look of skin tone. Here's how to make it work for you.

The benefits

• Antioxidant defence against UV- and pollution-driven free radicals
• Brightening — helps even tone and fade the look of dark spots and uneven tone
• Support for collagen, contributing to firmer-looking skin

How to use it

Vitamin C is best applied in the morning, before moisturiser and SPF, so it can defend against the day's exposure. Store it away from light and heat, and be consistent — visible brightening builds with regular use. It pairs naturally with copper peptides and daily sunscreen.

Getting the pairings right

Use vitamin C in the morning and retinol at night to enjoy both without irritation. A hyaluronic acid layer keeps skin hydrated alongside either.

Frequently asked questions

Why did my vitamin C change colour?

Vitamin C oxidises with light and air exposure. Store it sealed and out of sunlight, and replace it if it turns deep orange or brown.

Can sensitive skin use vitamin C?

Yes, though very sensitive skin should start every other day and build up gradually.
