Does Jessners peel solution go bad ever, loose its potency, or become more potent?

All medicines have a theoretical and actual expiration date. I would advise you to seek the advice of a trained chemical peel expert to administer a potent Jessner peel for your skin.Best, Dr. Karamanoukian Los Angeles

Jessner's can be very inflammatory and can cause complications if not done properly.  I suggest only going to a cosmetic dermatologist with experience in peels.  Best, Dr. Emer.

Jessner solution usually has an expiration date on the bottle.  These dates are determined by the maker of the peel and calculated by how long it takes for the active ingredients to lose their potency.  There are other factors that can change the date too such as additives or preservatives in the solution.  It is very important that the peel is not expired and used by a trained practitioner to achieve appropriate and expected results.
