Commonly used to improve the look of frown lines (glabellar lines) between the brows, crows feet at the corners of the eyes, forehead lines, laughter lines, to erase bunny lines on the side of the nose. This treatment involves a type of botulinum toxin type A being injected directly into the muscles between the brows or other areas being treated.
Botox is the leading brand of botulinum toxin type A and is the name most commonly recognised with muscle relaxing injections, also used is Azzalure which has been used in the UK since the early 1990’s.
Botox has been used since 1980 to treat a number of muscle disorders and can also be used to treat migraine and excessive sweating. It is a simple, non-surgical treatment that works by blocking nerve impulses to the injected muscles and this reduces muscle activity that causes lines and wrinkles to form, allowing the overlying skin to appear smooth and line free.
The appearance of frown lines and other treated areas will be dramatically improved within three to ten days of treatment. The skin will appear smoother and unlined whilst untreated facial muscles work as usual to allow the normal facial expression to be unaffected by the treatment.
Some minimal bruising may be experienced following treatment but side effects are rare. Occasionally temporary numbness or a mild headache may be experienced although muscle relaxing injections are used to successfully treat migraine in some patients. In less than 1% of patients a temporary droop of the brow or eyelid may occur.
The effects can last three to four months and then repeat injections will be needed to maintain the effects. After several treatments, the effects will begin to last longer and repeat treatments may only be required every six months.
