For a first vitamin C serum, choose a moderate strength (around 10%) or a gentle derivative, use it a few mornings a week at first, and always follow with sunscreen. Increase to daily use once your skin is comfortable.

What makes a good first serum

Beginners benefit most from a forgiving formula: moderate strength, no fragrance, and packaging that protects the serum from air and light. A very high percentage is not a shortcut; for L-ascorbic acid, absorption studies found no added benefit above about 20%.

Gentler options include 3-O-ethyl ascorbic acid, ascorbyl glucoside and sodium ascorbyl phosphate. Around 10% L-ascorbic acid is also a common starting point for non-sensitive skin.

A simple starting routine

Morning: cleanser, vitamin C serum, moisturiser, sunscreen. Night: cleanser and moisturiser. Keep other strong actives out of the morning routine for the first few weeks. Our step-by-step guide to using vitamin C serum and the morning or night explainer cover the details.

Frequently asked questions

+Can a 20-year-old use vitamin C serum?

Yes. Vitamin C is used for tone and antioxidant protection, not only for ageing, so it can suit adults of any age. People with very sensitive skin should start with a gentle form.

+How much serum should I use?

Usually a few drops or one pump covers the face and neck. Using more does not make it work faster.
