Vitamin C 10% Serum

Description

L-ascorbic acid is the form of vitamin C with the most research behind it. At 10% with 0.5% ferulic acid and vitamin E, it works as an antioxidant in the daytime and helps the look of dullness and uneven tone.

It only works at a low pH, so the formula sits at 3.0 to 3.5 and you may feel a light tingle for the first few days. The amber glass and a dropper that never touches the liquid protect it from light and air.

Suits: Normal, combination and oily skin. Dry or sensitive skin can start every third morning and build up.
