Botox has many uses. Some indications are medical and some cosmetic.
Areas thar can be treated with botox include:

Frown lines are a frequently treated area. Some people call them their 11 lines. Patients will often report that frown lines run in their families. Botox is an excellent treatment of frown lines. The effect of the treatment often lasts 4 to 5 months. Sometimes deeply etched lines will require additional treatment with filler.

Brow lift: Accurate placement of toxin results in a very efficient brow lift. This results in the client appearing refreshed and more awake looking. Sometimes a lateral Brow lift is also utilised.

Eye wrinkles are also called periorbital wrinkles or crows feet. Anti-wrinkle injections with botox result in an improvement of these lines. Not all eye wrinkles are suitable for this treatment and thus it is important to carefully assess each patient carefully before treatment. In fact in some cases botox can worsen the appearance of the eye area. In such cases it may be preferable to treat with with skin boosters, fillers, chemical peeling, PDRN, laser, microneedling or radiofrequency microneedling.

Gummy smile: Patients are often troubled by gummy smiles.
Interestingly there are different types of gummy smile. Careful pre-treatment assessment will guide the doctor on where best to carefully inject the toxin.

Nefrititi lift: the Egyptian goddess Nefrititi had a straight smooth jawline. In this treatment toxin is accurately placed to allow relaxation of the muscles that drag down the lower face.
In most people these muscles have become too strong over a period of years. These overactive muscles damage the lower face, jawline and neck resulting in an aged appearance. I feel that most clients need this treatment as prevention of the aging process in the lower face.

Teethgrinding(Bruxism): Botox is a suitable treatment for most cases of teethgrinding. I also advise the use of mouth shield but many patients find they can’t wear or tolerate these. I first carefully examine the patient to ensure that they are suffering from uncomplicated bruxism and if so I carefully inject the masseter muscles with toxin. This results in a substantial improvement in teethgrinding.

Excess sweating(Hyperhidrosis): Excessive underarm sweating is very efficiently treated with toxin. This generally lasts 5 to 6 months. Some people only get treated once a year in late spring or early summer when their sweating is worse.

Migraine/tension headaches: Botox can be a very efficient treatment of migraine and tension and headaches.

Lip Flip: toxin can be used to treat upper lip lines and also allow more show of the vermillion of the upper lip. I feel this is usually better combined with discrete filler or skin booster.
