How to Fix Scarring, Burns from Chemical Peel?

Chemical peels vary in depth and penetration of the skin. The most critical element in chemical peels is the preoperative assessment of patients before performing a procedure. I routinely perform deep TCA peels on a weekly, if not daily basis, with an excellent safety profile that is unmatched in the industry. This safety profile relies on a rigid pre and postoperative skin protocol and detailed preoperative assessment.
In your specific case, there are several things that can be performed to eliminate and improve scarring associated from a chemical peel. This includes prescription-based topical treatments and TAC treatment.

There is not a great way to undo the effects; if the TCA peel was recently, medical grade steroid or silicone creams can help minimize the secondary inflammation and decrease some of the areas of hyperpigmentation. They can also decrease the appearance of scars; consider trying Silagen or stratoderm. If it has been some time, then you can consider a non ablative laser such as Fraxel Dual restore to help improve the overall tone and texture.

Its hard to give you solutions without seeing a picture. If a TCA peel is done right- it is a safe and very effective peel. It shouldn't "burn" the skin. Get a formal evaluation by a dermatologist. In many cases, this may be able to be corrected. 

Scarring and pigment changes from peeling can be improved but there is no one solution. You need to be evaluated by a good plastic surgeon to get your options explained.

There are various strengths of TCA and some have no risk of scarring while others can carry a high risk. First of all, you need to discuss this with your treating doctor. Second, there are interventions that can help varying from laser to steroid cream and injections. If the peel is not blended onto the neck then you may see a step off of discoloration. First go to your treating doctor because they may be able to handle this if they have a lot of experience and if not then seek a dermatologist who specializes and is trained in cosmetic peels to get the best results

The white areas are may not be a scar, but rather depigmentation from the peel.
You may try skin bleachers like hydroquinones to help blend the color differences. If the scars are red and raised, post balm or mederma may help.
Be sure to keep out of the sun and UV. Other things to consider would be silicone sheeting.
Take comfort that things should get better over time.
