What happens after a BOTOX Cosmetic injection?
After BOTOX Cosmetic is injected into the targeted muscle, the weakening effect gradually begins over 3-5 days, and is not complete for two weeks. Therefore, optimal results are not seen until then. The effects of BOTOX Cosmetic usually last three to four months, at which time another injection is required. After several treatments, the effects often begin to last longer. Repeated use is truly anti-aging!
