Does a Tretinoin 0.05% w/w Cream help reduce melasma?

Tretinoin does feature in a lot of pigmentation treatment plans and can help with melasma over time, mainly by speeding up skin cell turnover. Melasma can be stubborn, though, and usually responds best to a combined approach rather than one product alone, and using tretinoin incorrectly can sometimes worsen irritation or pigmentation on sensitive skin. It's worth seeing a dermatologist first, so they can build a routine, sun protection included, suited to your skin and how severe things are.
