Chemical burn from Retin A and Lactic Acid use? (Photo)

You essentially performed a medium depth peel on yourself.  You will heal fine, but will likely become a little darker or lighter in the area for a short period of time.  You should avoid any scrubs, harsh topical creams, or any other peels for now; moisturize the area with a cream such as cerave during the day and aquaphor at night; a broad spectrum sunscreen should be placed on at least twice daily; and you should see a dermatologist with expertise in chemical peels and lasers, as they will be able to manage your complication and get you on the right track.  I would suggest contining with a dermatologsit you trust to perform peels and manage your future skin care.  I wish you the best of luck, Dr. Emer.

Self treatment can be very dangerous and should be avoided. I would suggest visiting a local board certified physician immediately to prevent any permanent damage. I would suggest you discontinue use of any products aside from a mild moisturizer until the situation can be addressed by a professional.

The best advise is 1. STOP self treating, 2. Seek in person opinions from boarded docs in your city/state...
