The treatment involves a number of small injections in the areas to be treated. The effects of the Botox® take a week or two to appear. In the beginning, the effect of a session will last up to 4 months. After a two or three treatments, at intervals of a few months, the effect of the treatment will last longer. After a year or so of treatment, the areas being treated by Botox® gradually relax and further treatments are only required perhaps once a year.
There are few unwanted side effects of treatment. Any side effects of treatment are temporary and may involve mild bruising at the site of the injection and occasionally a passing redness and slight swelling of the treated area which usually lasts less than an hour.
When the frown lines are treated, about one percent of people (one in a hundred), experience a partial eyelid droop that can last for two or three weeks. This uncommon event happens when Botox® for a variety of reasons may move sideways into the eyelid. This rare side effect can be reduced if it occurs, by use of a particular eyedrop.
