Also known as: L-Ascorbic Acid, Ascorbyl Glucoside, THD Ascorbate
What it actually does
A brightening antioxidant that helps fade dark spots, even out tone and add glow with regular use.
How to use it
Best in an AM serum before sunscreen. Store away from light and heat — brown or oxidised Vitamin C has lost its potency.
The science, in plain English
L-Ascorbic Acid is the most-studied form — potent but unstable. Derivatives (SAP, MAP, THD) are gentler and more stable.
Myth vs reality
10% is not automatically "better" than 5% — form and pH matter more than percentage alone.
Pairs well with
- Vitamin E
- Ferulic Acid
- SPF
- Hyaluronic Acid
Don't layer with
- High-strength Niacinamide in the same layer
- AHAs/BHAs on the same morning
