# Vitamin C

## Quick Summary

Vitamin C is used in skincare for brightening, antioxidant support, and the look of more even tone. In post-acne dark spot routines, it is a supporting ingredient rather than a scar-removal claim.

## What It Is

Vitamin C is a family name in consumer skincare. This page uses Ascorbic Acid as the INCI anchor while noting that product formulas may use different vitamin C derivatives.

## Mechanism

The cosmetic goal is brighter-looking, more even-looking skin over time. Vitamin C does not fill pitted scars or remove raised scar tissue.
