How do I treat this rash caused by an at home chemical peel and what is it?

Thanks so much for your question 
It looks like contact dermatitis 
It will go away it might take 1-2 weeks
Get a prescription hydrocortisone cream 1% and take traction and don’t use anything else
Good luck

it almost looks like an allergic reaction. I can not for sure day to what. You could try an antihistamine over the counter and ser if that will help. If it does not give relief please see a doctor/ dermatologist near you. It should resolve completely. One of the features of an allergic rash is it hing. If you do have an itch it likely is allergy. So difficult to say with that picture alone. Good Luck!

Dear Atlanta,Thank you for the inquiry.A moderate medical grade peel depth will typically start sloughing the surface skin after 2-4days, and persist upto a week. Your otc peel may be less strong, and just causing the skin to bubble at the surface but not peel.The biggest concern with deeper peels is skin scarring and infection.Continue oral Benadryl and see your local skin specialist.Best.
