How long after IPL can I go back to using glycolic acid and retain a?

Thank you for your question.  Here at Stillwater Plastic Surgery we suggest returning to retinol or other more aggressive products several days after your procedure.  It is always a good idea to wait until your skin feels like it is no longer sensitive and back to normal.

It really depends on the sensitivity of your skin. Some people can use it the following day and some need to wait a few days. There's not a safety factor in using it, just a sensitivity factor for your skin. "This
