Which of these peels must be neutralized: glycolic, salicylic, TCA, lactic acid, Jessner?

The peeling agents are available online.  That does not mean you should order them and apply them to yourself.  A great deal of judgement is required to safely perform a facial peel.  Do yourself a favor and find an experience dermatologist or cosmetic surgeon to do your peels.

Thank you for your question. From the peels listed that must be neutralized is the Glycolic Acid peel, the other peels are self neutralizing. Peels are easily applied, but can cause many issues/problems if not done correctly. I would recommend you find an experienced dermatologist or cosmetic surgeon to do your peels. - Dr. Dickerson

The only peel of the ones you listed that must be neutralized ("stopped") is the Glycolic Acid peel.The other peels are self neutralizing, which means that they eventually "stop" on their own, without you needing to apply a solution or water to "stop" them.Chemical peels are fairly easy to perform, however they are a MAJOR cause of problems when done by patients at home: patients don't know which peel to pick, how long to leave on to get the desired result, what are danger signs during the peel, and how to properly neutralize. Not all peels are interchangeable and many are unsafe above certain concentration in dark skinned patients.Be well-
