Why are you required to stop using them days before a chemical peel is performed. I am going to perform a 15% TCA Peel on my face. I am indian and of light brown skin. I have already performed a TCA peel once. I have been using Tretinoin always before a peel to prep my skin for it. I just want to know why we are required to stop.
Why Do You Have to Stop Using Retinoids Before a Chemical Peel?

Caution Using TCA in Indian Skin
Tretinion can be used for skin care except a few days before a chemical peel and during the healing process. What concerns me is your use of unsupervised TCA on your face. I am Pakistani (light brown skin) like you. I would not allow my Indian or Pakistani patients to use TCA on their own. Please be very careful and better yet let a physician do it for you.

Have a question? Ask a doctor
15% TCA is so mild.
However, you did not tell us how often you are using Retin A. Daily use is often so irritating that it is not recommended.
In my practice, patients are allowed to use their Retin A on their usual schedule up to the night before a peel. Generally we ask that they do not resume treatment until about a week after such a peel.
You did not indicate if a physician was performing your peel. This type of peel should not be performed without direct physician supervision. Ideally the physician is performing this service.
Too much of a thing may be damaging
Retinoids have the ability to strip the supper layer of the skin and cause a very superficial peel. If not stopped prior to a chemical peel in the doctor's office, that peel becomes exaggerated. For example a 15% TCA might have the effect of a 20%. This makes it difficult for the treating physician to control the depth of the peel based on the indication at hand.
