Food and Habits for Dark Spots
Can food or habits help dark spots?
Nothing on a plate is shown to fade them; sun protection is the habit that counts
No food has been shown to fade dark spots. The habit with the best evidence is daily sun protection, which slowed visible sun damage in a randomised trial. A few supplements have been tested for skin lightening, with small and inconclusive results.
What does have evidence
In a randomised trial of 903 adults in Australia, people who used broad-spectrum sunscreen every day showed 24 per cent less skin ageing over four and a half years than people who used it as they pleased. Reviews of melasma and other pigment conditions describe sun protection as central to preventing and managing them.
Light beyond UV
Reviews note that long-wave UVA and visible light can also darken pigment, especially in deeper skin tones, which is one reason tinted sunscreens containing iron oxides are being studied. Ordinary UV-only protection may not be enough for melasma.
Foods and supplements
We cover the claims people ask about on our dedicated page: whether anything you eat fades spots, and what trials found for oral glutathione. The short version is that results are small, short and inconclusive.
For dark spots
No food fades dark spots. Daily sunscreen is the habit with the strongest evidence for keeping sun damage from adding up.
What your routine does for pigmentation
Food and habits sit beside a routine, not in place of one. See which ingredients are worth using for pigmentation, ranked and with how to introduce each one safely.

We did not find a trial showing that eating vitamin C foods fades dark spots. A survey did link higher vitamin C intake to fewer wrinkles, which is a different outcome.
