What it does
- Vitamin C is an antioxidant; studies show topical vitamin C may help protect skin from some of the damage caused by UV exposure when used along with sunscreen.
- Reviews report that vitamin C may help the look of dullness and uneven tone, including dark spots, with regular use.
- Some studies suggest vitamin C may support collagen, which may help the look of fine lines over months.
- Stable derivatives (such as ethyl ascorbic acid) are gentler for some people, but there is less clinical data on them than on L-ascorbic acid.
How to use
Apply 3 to 4 drops to clean, dry skin in the morning, before moisturiser and sunscreen. Vitamin C does not replace sunscreen. Store the bottle closed, away from heat and light; if the serum turns dark orange or brown, it has likely oxidised. Start every other day if your skin is sensitive. Patch-test behind your ear or on your inner arm for 7 to 10 days before using it on your face.

Frequently asked questions
Vitamin C serum day or night?
Morning is common because its antioxidant effect may add to your sunscreen. You can use it at night too. What matters more is using it regularly and always wearing sunscreen in the day.
Can I use vitamin C and niacinamide together?
Yes. Most people can layer them. If you notice flushing or stinging, use vitamin C in the morning and niacinamide at night.
Which percentage of vitamin C serum should I use?
Studies on L-ascorbic acid usually use 10% to 20%. Higher is not always better because irritation rises. If you are new, start around 10%.
Why did my vitamin C serum turn orange?
Vitamin C oxidises when exposed to air, light and heat, and the serum darkens. A dark orange or brown serum is likely less effective; buy smaller bottles and keep them closed and cool.
Can vitamin C serum remove pigmentation?
It may help lighten the look of dark spots over weeks to months, but no serum can promise to remove pigmentation. Sunscreen is essential.
Can I use vitamin C with retinol?
Yes, at different times: vitamin C in the morning and retinol at night is a common, gentler way to use both.
Vitamin C serum side effects
You may feel tingling, mild redness or dryness, especially with stronger or low-pH formulas. Patch-test, start every other day and stop if irritation does not settle.
Is vitamin C serum good for oily skin?
Yes, many serums are light and water-based. Pick a non-greasy formula and follow with a light moisturiser and sunscreen.
