How long should I wait after I quit smoking to get subcision for acne scars and botox for frown lines?

Hi and thanks for your question.  We always prefer that patients quit smoking before any cosmetic procedure but for what you describe above I would have no problem doing Botox, HA filler, subscision even while you're trying to quit.  I prefer not to do resurfacing laser in patients who smoke.  The sooner you quit, the more collagen you're preserving.  Do it today!!

Usually I request a minimum of 2 weeks prior to the procedure.   It takes some time for the effects of smoking to reverse.   Once you stop just stay a non-smoker.   There is no need to fix your face just so you can get lung cancer.
