Brightening & tone
Vitamin C
also known as L-ascorbic acid, ascorbyl glucoside
The morning antioxidant — brightens, evens tone, and buffers daily UV and pollution damage.
What it actually does
Vitamin C neutralizes the free radicals UV light and pollution generate in your skin, interrupts pigment production, and is a required cofactor in collagen synthesis. Pure L-ascorbic acid (at ~10–20%) is the most potent and the most fragile — Korean formulas often use stable derivatives like ascorbyl glucoside or 3-O-ethyl ascorbic acid that are gentler and last longer in the bottle.
Who it's for
Anyone with sun-related dark spots, dullness, or post-inflammatory marks. Sensitive skin should start with a derivative rather than pure L-ascorbic acid.
How to use it
Morning routine, before sunscreen — it amplifies the protection SPF gives you. Bottles that arrive clear and turn brown are oxidized and won't do much; that's why most well-formulated vitamin C ships in airless or amber packaging.
