Background

Botox^® has been used for many years to treat muscular problems including eyelid and facial spasms. Ageing is associated with the development of wrinkles and furrows on the face. These lines may develop as a result of weakened dermal collagen from sun exposure and gravity, or due to facial muscle action on the skin.

Botox for Frown Lines and Smile Lines

Botox^® or Botulinum Toxin temporarily weakens the muscle. Therefore it may be used to treat facial lines caused primarily by the action of the muscles on the skin. The ideal areas to treat are those wrinkles caused by muscles that have no significant function. Examples include, the deep crease between the eyebrows, crows feet wrinkles and forehead lines.

Injection into frown lines has shown to be very successful. Good results may be obtained after a single injection and results last from 3-5 months. Some patients with very powerful muscles may not see a complete relaxation of the targeted area, but subsequent injections will further weaken them. In rare cases, some patients may need a repeat injection within four weeks if there has been little response.

Do the Injections Hurt?

Because the needle is so fine, most patients find that the injections only cause mild, temporary discomfort.

How Many Treatments will I Need?

Repeat treatments are usually needed every 3-4 months over a 12-month period. Clinical trials report that some patients, who have had treatment over 12 months, are only requiring further treatments once or twice a year.

It can take up to 14 days for the Botox^® to work. Excessive use of the muscles for 2 hours after treatment helps speed up the onset of effect.

Possible Side Effects

Side effects of this treatment are rare. Mild localised bruising and redness may occur. Very occasionally, a temporary drooping of the eyebrow or eyelid can happen, but this resolves in a few weeks.

Rarely, a transient numbness may develop in the treated area. An extremely rare side effect may be generalised weakness and fatigue. In one study less than 3% of patients experienced any of these complications. Finally, any injection carries a small risk of infection. Please inform the treating Clinician of any medication that you are currently taking.

If you are pregnant or breast feeding the treatment is not recommended. Please note that Botox, although FDA licensed in the USA is also licensed in the UK under the name of Vistabel^® for forehead frown lines and hyperhidrosis (excess underarm sweating).
