Repeated contraction of the muscles of the face when we smile, talk, frown and chew result, with time, in lines, that end up marking the skin. By reducing the ability of the muscle to contract, these lines are no longer formed and will soften over time, as the overlying skin has time to recover. Anti-wrinkle injections are recommended when the lines remain visible when the muscles are not contracted, at rest.
Botox injections are done in specific areas to minimize the action of specific muscles, reducing its contraction and therefore the wrinkles formed by it. The result takes 3-7 days to appear and usually lasts for 4-8 months, depending on the area treated.
The most common uses for anti-wrinkle injections are for treatment and prevention of crow’s feet, frown lines, forehead lines and bunny lines (nose). Great results can also be achieved in the treatment of gummy smiles, reducing the activity of the muscles that pull the upper lip up when smiling. Botox can also be used to reduce the activity of overactive muscles in patients suffering from grinding and clenching, usually in conjunction with a night guard.
