More and more people are turning to Cosmetic Doctors for rejuvenation techniques, to help their face reflect the way they feel inside.

One such rejuvenation technique is Botox. It can be used to relax the specific facial muscles that cause glabellar frown lines to form.

The following information details how Botox works and what is involved with treatment.

What is Botox?

Botox is a natural, purified protein that relaxes wrinkle-causing muscles creating an improved appearance. The active ingredient in Botox is botulinum toxin type A derived from bacteria in much the same way penicillin is derived from mould. It is manufactured in sterile laboratory conditions.

Botox is a prescription only medicine and as such is only available from your doctor. It is registered for the treatment of glabellar frown lines, which are the vertical lines that appear between your eyebrows when you frown.

How does Botox work?

Many facial wrinkles occur when we use our muscles to make repeated facial expressions. Botox can be used to relax specific facial muscles that cause expression lines. Once the muscles are relaxed, you cannot contract them and continue to make the undesirable facial expressions. Thus, the lines gradually smooth and new lines are prevented from forming.

What does treatment with Botox involve?

It is a non-surgical treatment whereby a small amount of Botox is injected into selected facial muscles by your doctor using a very fine needle. Generally, Botox treatment for glabellar frown lines takes around 10 minutes.

Discomfort is typically minimal and brief, and no anesthetic is usually required. The injection may sting for a few seconds but normal activities can be resumed soon after. After the injection, it takes 2-3 days for Botox to begin taking effect and about 7 days to see the full effect.

The dose recommended for the treatment of frown lines will vary depending on your individual situation and the severity of your frown lines. Your doctor will know what the best dose is for you and which muscles to inject to give you the best results.

How long does Botox last?

The effect can last up to 4 months before lines slowly begin to return. If you have repeat Botox treatments, the effect tends to last longer.

Does Botox cause more wrinkles to form?

Botox relaxes the facial muscles that cause expression lines, it does not cause more wrinkles to form. If you choose not to have further Botox treatments your muscles will eventually return to normal activity and your wrinkles will gradually revert to their pre-treatment levels.

Will facial expression be affected by Botox?

Botox works specifically on the muscles treated. This means that any muscles left untreated, including untreated facial muscles, should not be affected by Botox. Your doctor will determine the best dose for you and which muscles to inject to give you the best results.

Are there any side effects?

In addition to its use for cosmetic reasons, Botox is also used to treat patients of most age groups in a variety of therapeutic indications including cerebral palsy in children, movement disorders (head, neck, shoulder, face), and axillary hyperhidrosis (excessive under arm sweating).

In the amounts used for the treatment of frown lines, the side effects are usually temporary and localised to the area of injection. Possible side effects include headaches, pain, burning, bruising or redness at the injection site, local muscle weakness including drooping eyelids, lack of feeling, skin tightness and nausea.

Can Botox be combined with other products and procedures?

Many people use a combination of cosmetic products and/or procedures with Botox. Your doctor will advise you as to whether or not you will receive better results if Botox is combined with other products and/or procedures.
