What is Vitamin C (skincare)?
Also known as: Ascorbic Acid, L-Ascorbic Acid, C vitamini
Short answer
Vitamin C is a strong antioxidant in skincare; it protects against free radicals, brightens skin, and helps improve spots and uneven tone. It is safe, but the pure form (L-ascorbic acid) can irritate some skin at low pH.
What is Vitamin C (skincare) and what does it do?
In skincare vitamin C appears mostly as L-ascorbic acid or more stable derivatives (such as Sodium Ascorbyl Phosphate, Ascorbyl Glucoside). With its antioxidant effect it works to reduce oxidative stress from sun and pollution.
Benefits
By neutralizing free radicals it supports daytime sun protection, brightens the skin, helps lighten spots by balancing melanin, and plays a role in collagen production.
What to watch for
Pure L-ascorbic acid oxidizes easily in air (if the product turns yellow its potency has dropped) and the low pH it works at can cause tingling/redness on some sensitive skin. Derivative forms are gentler but usually act more slowly.
How to use it
Usually used in the morning after cleansing and before sunscreen (for antioxidant protection). Prefer dark, air-tight packaging; a yellowed product is time to discard.

Frequently asked
Vitamin C morning or evening?
For antioxidant protection it is usually used in the morning under sunscreen; it can also be used at night.
The product turned yellow, is it usable?
Yellowed pure vitamin C has largely oxidized and lost potency; a slight color shift is tolerable, but if it turns dark brown, replace it.
Can it be used with niacinamide?
Yes, in modern products they are used together safely; the old 'do not combine' claim has been debunked.
