Detailed answer

Melasma patches, which are caused by an overproduction of melanin in the skin, can potentially lead to scars when the pigmentation is treated using certain methods such as laser therapy or chemical peels. However, keloids, which are raised scars that extend beyond the original wound, are not commonly associated with melasma. Keloids are more likely to occur in individuals with a genetic predisposition to scar formation, and melasma does not typically trigger keloid development. Therefore, while melasma patches can potentially result in scarring, the risk of keloid formation is minimal.
