A peel marketed for discoloration or wrinkles deserves a supervision check before it reaches your bathroom shelf.
The percentage is only one factor
FDA explains that acid concentration, repeated applications and time on the skin all affect penetration and burn risk. Reported consequences include infection, pigment changes and disfiguring scars. A percentage on a bottle cannot supply a personal treatment plan. [1]
What 18 injury reports can tell us
A 2025 case series by FDA researchers identified 18 injuries after nonprofessional application. They searched FDA reports, published cases and Amazon reviews with images from August 2018 through August 2023. Consequences included reduced mobility, disfiguring scarring and emergency, dermatologic or surgical care. [2]
Underreporting, incomplete clinical information and consumer-review bias limit the findings. These reports do not establish how often injuries occur, compare treatment options or measure GLP-1 users' risk. [2]
Bring more than your skincare list
AAD recommends disclosing current or past isotretinoin, other recent medicines, supplements, cold sores, easy scarring and previous surgery or cosmetic treatments. Include your GLP-1 prescription in that medication history. [3]
Ask who will perform the peel, their experience with your skin coloring, your complication risks, preparation, aftercare and downtime. Take those questions to the consultation before choosing a product. [3]
This is US safety and preparation guidance, not evidence that peels prevent or reverse GLP-1 appearance changes. For irritation-related discoloration, see our dark marks guide.
