Hyperpigmentation
Some evidence
Vitamin C: 7 studies tested it on its own. See all 24 studies
What the studies found
- Most studies found vitamin C helped fade dark spots or patches
- In melasma studies, vitamin C on the skin often made patches look lighter over time
- Used with other treatments, vitamin C sometimes faded melasma more than the other treatment alone
- For sun spots, vitamin C showed some fading, but one study had mixed results
- It worked about as well as glycolic acid for fading melasma patches in one large review
Research context, not treatment advice. Studies are about the ingredient, not necessarily this exact product.
