I don't think this is necessary but the company recommends stopping the Retin A a few days before and few day after the procedure. I see no reason to do so. It will help prevent acne that some people get with the procedure. The night of the procedure holding Retin A might be a good idea because there are still micropenetrations which remain open. Other than that, continue the cream.
Stop the cream, it may cause unwanted irrigation, re start 7 days after the treatment. Doxycycline, continue, as INFINI is not light based, so all good. Even then for most light based laser systems the action spectrum of Doxy is in the long UVA, so lasers etc... will not effect it. I often PLACE my patients on doxycycline after INFINI RF to help reduce inflammation and prevent infection. All good to continue. Dr Davin Lim, Brisbane. Australia.
