How do I fix a chemical burn on my face?

please see a cosmetic dermatologist with experience. also posting photos or a formal consultation will help decide what can be done.  Best, Dr. Emer.

I usually have my patients start tretinoin creamvery slowly and take 3-4 weeks to work up to daily use. Initially when topical tretinoin cream is applied the acne may get worse. That is precisely the reason that I do not start my patients on tretinoin cream. You need to be careful what you wash your skin with when using this product. I usually prescribe or dispense a special cleanser containing cetyl alcohol to be used prior to tretinoin applicationto avoid irritation and drying. I personally do not advise using a cleanser such as Clearasil Ultra Face Wash prior to topical tretinoin cream because it contains 2% salicylic acid which causes peeling. When these are use together the skin could dry and peel abd become quite uncomfortable. I prefer to use benzoyl peroxide and tretinoin in many of my patients and usually begin with benzoyl peroxide and add the tretinoin in about two weeks

First I would check with your dermatologist as each physician has their own approach to these problems and consistency is key.  As a general rule using a moisturizer like Cerave CREAM, not lotion, and a daily sunscreen with zinc oxide to help protect against post-inflammatory hyperpigmentation.  You probably want start out the medications every other day.
