I think it does a little bit of both. it helps to prevent new ones as well as camouflages the ones you have. Notice I said help prevent new ones as nothing can truly stop the aging process. i was speaking with a friend on the west coast who has a plastic surgeon in beverly hills that was on the fda trial tests for botox. one of them tested was a twin and shes been using botox ever since then (for 12 years now) and the other twin that lives in germany hasnt. well it turns out the twin that was using botox looks as if her facial skin hasnt aged yet her twin that never got botox is completely opposite. i think what the makers of botox will start to do to sell even more of their product will start pitching it as a preventive treatment to prevent signs of aging. when they lose their patent theyll almost certainly be resorting to marketing like this im sure.
