# Vitamin C Irritation

## Quick Summary

Vitamin C irritation is the stinging, burning, redness, or tight feeling some people get from vitamin C products. It is more common when skin is already sensitive, over-exfoliated, or using too many actives.

## Causes

Low-pH L-ascorbic acid formulas, high-strength serums, daily use too soon, broken barrier, retinoids, exfoliating acids, or fragrance can all make vitamin C harder to tolerate.
