A “melasma mustache” is actually simply hyperpigmentation gathered over the higher lip, therefore the identify. Some might expertise melasma in different areas of the face, just like the brow and the cheeks, however the upper-lip space is tremendous frequent.
“Though melasma can happen in males, it is far more frequent in ladies and extra frequent in these taking oral contraceptive capsules and through being pregnant,” board-certified dermatologist Rebecca Marcus, M.D., tells mbg.
Scientific research present that UV radiation is the commonest preliminary set off of melasma, in addition to the primary issue exacerbating preexisting patches. “Even a tiny little bit of solar could cause melasma to flare in those that are inclined, and even warmth, within the absence of solar, has been identified to trigger a flare,” Marcus says.
Hormones are additionally a standard reason behind this sort of hyperpigmentation (which is why it is generally triggered by contraception capsules and being pregnant), although it is unclear if the upper-lip space is extra often affected by considered one of these triggers or the opposite.
Nonetheless, in case you are solely experiencing hyperpigmentation above the lip, you could wish to look into your skincare practices as effectively—hair elimination strategies included. “I consider that melasma flares within the upper-lip space are often triggered by hair elimination. Whether or not laser (warmth plus mild) or mechanical trauma from waxing or threading, sure hair elimination modalities can set off irritation that will result in a melasma flare-up,” Marcus explains.
So whereas the actual cause for the melasma mustache continues to be barely unknown (particularly if different patches of hyperpigmentation aren’t current), hair elimination could also be one thing to think about.
