Botox is a protein derived from bacteria. When injected into a muscle, the muscle will be immobile for about 3 months. Therefore it is only injected into muscles that do not have important function. Botox treatment diminish the effects of facial wrinkles caused by muscle contraction. The following muscles can all be improved for several months with a single treatment.
- Crow's feet smile lines (obicularis)
- Frown lines (glabella)
- Forehead furrows (frontalis)
- Laugh lines (nasolabial) Botox is injected into the tiny facial muscles that create the wrinkles and the muscle cannot contract.
- While very effective, the results are not permanent and need to be repeated two to three times per year to retain the desired effects. Repeated use of the injections may lead to a longer duration of each treatment's effect Botox treatments can also be used to alter the shape of the eyebrows.
- The eyebrows can either be raised or dropped.
- Botox is only useful in treating expression lines and cannot be used to repair sagging skin caused by aging.
