Do I have to wash my face after a Jessner peel? How long can I keep the peel on?

If you are inquiring because you are attempting this peel at home, please do not proceed. There are licensed professionals to administer this for a reason. You can permanently damage your skin. If you have gone to an office to get this treatment done, please call the office to ask them what their post op instructions are.

Thank you for your question.
Every plastic surgery office has their own set of pre and post operative instructions that they recommend their patients follow. It is most important to follow the instructions of your surgeon.
