Did I give myself a chemical burn with 25% TCA peel? I have really red areas and dark brown spots

Yes, you have burned your skin. I recommend seeing a board certified dermatologist for immediate care for these areas. This is simply not a product that should be used by untrained individuals. In the right hands and on the proper areas of the body, it can be helpful. On areas like the chest and shoulders, it can actually cause scaring. Don't do this again. This is a terrible way to "save" money.

I don't recommend doing peels yourself, due to the risk of complications. I recommend getting a formal evaluation with a cosmetic dermatologist for after care and treatment. These spots can be improved with a combination of lasers, Aerolase, microneedling/prp, skin lightening, peels, and skin care. Sun protection is essential. I recommend getting a formal evaluation with an acne scarring expert. Best, Dr. Emer

Hi,A 25% TCA peel is a strong peel.  It's one that really should be administered by trained professionals.  It appears that you have burned yourself.  Please seek evaluation and recommendation by a dermatologist.  You may be at risk for post inflammatory hyperpigmentation.Best,Dr. Huo

Technically this is NOT a burn as if one does aggressive pre-prep and or multi coats with TCA, the brown areas are normal. What is not clinically acceptable is the demarkation. Ideally the peel is even and buffered out. As you know once this frosts, the peel is done. No neutralisation need. Best look after your skin with emollients and meds to reduce incidence of infection. SPF- UV protection needed for 4-6 weeks post peel. Demarkation should fade in 2-6 month if there are no secondary problems. Dr Davin S. LIm, Brisbane. AU
