Botox can be injected in a number of locations. For cosmetic procedures, it can be injected in a number of locations on the face. It is FDA approved for injection into the glabella, the area between the eyebrows, to improve frown lines. It is also used in the forehead to improve the horizontal wrinkles formed when one raises one's eyebrows. It can also be injected into the crow's feet areas, those areas just beside the eyes which form wrinkles when a person smiles. Botox can be injected into specific locations in the forehead and around the eyes to produce a non-surgical facelift. It can improve the so-called smoker's lines, the vertical lines above the upper lip when injected in small amounts in these areas. It can lift the edge of the mouth if injected into the DAO muscle in the lower face. Less commonly, it can also improve neck lines and chin lines.
Botox does not work on all wrinkles. For example, the nasolabial folds, also called smile lines, do not improve with Botox injections. Fillers such as Juvederm work well in these areas.
Botox is used by doctors other than dermatologists and plastic surgeons for other indications. For example, it has recently been approved by the FDA for use in the therapy of migraine headaches. This has been highly publicized. It can also be used to improve hyperhidrosis, or excess sweating, in the palms, underarms, and soles of the feet. The amounts used for these purposes are significantly higher than those used on the face.
