Dark Nasolabial Lines After Alpha Beta Peel

Hyperpigmentation can happen as a side effect of peels, and is more common in darker skin types. Please keep your skin covered up because sun exposure can make it worse. In time, it may improve. You can also consider another type of peel, as suggested by a plastic surgeon or dermatologist.

Please do not use that peel again. You have most likely developed PIH (Post inflammatory Hyperpigmentation). It is the darkening of skin after an injury such as a chemical peel. In your case it only happened in the smile lines (nasolabial grooves) that extend from the nose to the lips. The reason is that more of the chemical settled in the grooves by capillary action as opposed to the flat or convex areas like the cheeks etc.
You should see a dermatologist. Start using sunscreen every single day, even when it is snowing outside. It should get better on its own. If not, then you might need a bleaching cream. A prescription cream called Triluma might help expedite the resolution.
