Vitamin C (10%)

What is it?

Vitamin C at a 10% concentration refers to a specific formulation strength of ascorbic acid or a vitamin C derivative, commonly called out on product labels as a mid-range strength between gentler low-concentration formulas and more intensive high-strength serums.

What does it do?

Commonly used at 10% as a moderate-strength antioxidant formulation intended to balance efficacy with tolerability for regular use. Clinical evidence for vitamin C broadly (see the separately catalogued Vitamin C and L-Ascorbic Acid entries) supports antioxidant, collagen-synthesis-cofactor and tyrosinase-inhibition benefits at this concentration range, which sits within the commonly studied 5%-20% effective range.

How to use

Typically formulated at 10%.
