Botox is most effective on wrinkles that haven’t quite set — “dynamic” wrinkles that appear while you’re moving your face, such as when you frown. “If you don’t move the muscle too much, you won’t form the wrinkle.
Side effects are possible: headaches, bruising, pain at the site of injection, and, in fewer than 1% of cases, drooping eyelids or eyebrows that return to their natural position within a few months.
If you decide to give it a try:
You’re more likely to get a bruise at the site of the needle injection if you’re taking aspirin or ibuprofen; these medications thin the blood and increase bleeding which causes the bruise. Skip the pills for two weeks in advance of your treatment. You should also tell your doctor — before treatment — about any supplements you’re taking, even if they’re “natural,” because some (such as fish oil pills, gingko, or vitamin E) also thin blood.
