I have butt acne and I'm going to do a 25% tca peel. How long I should leave it on to see the best results? (Photo)

Our treatments use combination therapy to improve the epidermis and dermis for most deep scars. The options available for acne scars depend on the character of your scars, in terms of topography and contour. We see atrophic and hypertrophic acne scars, as well as scars that have hypo and hyperpigmentation. We begin each scar evaluation with an assessment of scar quality and subtype. Our main concern is rebuilding collagen and that is why we use a HIDEF protocol that includes combination therapy. Morpheus 8, scar subcision, fibrous release, fractional laser, CO2 laser, Thulium laser, PDL Vbeam laser, and fractional resurfacing can be used in addition to TCA Cross and chemical peels to further improve skin. Patients should start Melarase AM and Melarase PM for active hyperpigmentation. Always begin with a consultation to decide whether early subcision should be started.

I don't recommend applying TCA peels yourself, due to the risk of complications. I suggest getting a formal evaluation with a cosmetic dermatologist. Acne requires a combination approach to get long term improvement. I recommend a combination of peels, lasers, microneedling/prp, blue light, radiofrequency and isotretinoin. Best, Dr. Emer

Thank you for your question and for submitting your photo.  Chemical peels, particularly those with higher strength acids like TCA, are a very complex procedure and require a great deal of expertise.  If not applied properly, there is a relatively high risk of side effects and complications, including burns and permanent scarring.  As a result, I strongly recommend against attempting TCA peels at home.  
Please consider seeing a board-certified dermatologist to discuss the best treatment options for you.
