A topical anaesthetic is usually applied prior to this treatment and Botulinum toxin injections are strategically placed to reduce the appearance of the lines around your top lip.
Treatment is quick; usually less than 30 minutes, and doesn't hurt; you will simply feel a 'sharp scratch' when the needle goes in.
There may be some redness and swelling, which will calm down a few hours after treatment.
Results will take two weeks to become fully apparent and should last between three to six months.
