In the chin area Botox usually lasts 3-4 months. But I have seen patient with results lasting up to 6 months. Botox can not permanently weaken your muscle, so be patient, it will start wearing off soon.
YES - indirectly by placing Botox in the Depressor anguli oris (DAO) muscle- a depressor of the lower lip-you can raise the commisure of the lower lip, this in turn raises the corner of the upper lip. Small amounts in the upper are can create a 'curl' of the upper lip but does not reduce...
After Botox it is recommended that little pressure be applied to the treated area for 24 hours and that you remain upright for several hours after injection. If you are concerned with your results you should return to your treating physician for assessment. Best, Dr. Green
