Does Botox Affect Melasma?

Botox has not exacerbated melasma. If a numbing cream is applied prior to the administration of Botox and should an irritation occur from this application, then melasma could be worsened. Any physical irritation or rubbing or sunexposure can worsen the melasma.

Melasma, or the 'mask of pregnancy', is discoloration or hyperpigmentation patches usually around the cheeks, nose, and upper lip. It is best treated or improved with cessation of oral contraceptives, intense pulse light lasers, hydroquinone or agents such as Cosmelan. Botox has no effect on melasma. Botox is a neurotoxin that will improve dynamic wrinkles by relaxing or temporarily paralyzing muscles.
