Botox and Dysport

Botox and Dysport (both Botulinum toxin Type A) are neurotoxins useful especially to treat and prevent wrinkles mainly in the upper face. They can take the tension out of a face and make a face look more relaxed and youthful.

They work by weakening muscles which are responsible for wrinkles. By removing the cause, the wrinkle fades and becomes less noticeable.

The products act only locally and highly selectively on the treated muscle. They do not freeze the face or the expression. I like to use them to selectively weaken muscles, not to paralyse your face so that you cannot express emotion. It is important that your face remains expressive, but that the product is effective in helping the wrinkles to fade. Areas which can be treated and the Botox doses required for treatment (Dsyport units required are different, but costs for the equivalent amount are the same) are as follows:

Frown line 20 units
Horizontal forehead lines 15 units
Crow’s feet 7.5-10 units per side, 15-20 units
Upper lip 5 units for the whole lip
Chin to improve wrinkling 10 units
To improve the mouth posture from unhappy to happy 10-15 units
Neck bands 20 units

Men usually require about 5 more units per area.

Treatment involves simple and relatively painless injection (said to feel like an ant bite sting). Injection tends to be a little more painful when you are pre-menstrual or menstrual. Treatment is performed in the rooms at the time of consultation and requires no anaesthesia. Small bumps and a slight redness due to the injection last about half an hour. Muscle weakness starts only 1-2 days after injection and takes about a week to reach full effect. Muscle function will begin to return after about 3-6 months, but this is often slightly weaker than before.

The injection should be repeated regularly for best effect. These products are very safe. Used properly, complications are extremely rare. Despite widespread use, toxicity has not been reported.

Occasionally the effect can be excessive and problems such as eyelid droop or tearing can occur, but always this is only temporary. Some bruising and occasional headache may be experienced for a few days after injection.

First used in 1973 for the treatment of squints, Botox has recently been licensed by the FDA for the cosmetic treatment of certain wrinkles. Botox and Dysport work by inhibiting the release of acetylcholine, a neurotransmitter, at the junction of the nerve with the muscle.

Dear Dr Lazarus,

I wanted to say that you are amazing! My face is beginning to settle down nicely.

The best thing is the comments I have received from some of my colleagues. One said, ‘Your face is unbelievable. The surgery must have been very advanced.’ Another person said, ‘Oh My ***, you look so YOUNG … I am shocked!

I will send you a photo but it is not a close up just a normal one to give you an idea. I am wearing a little concealer. I will send you close ups soon.

I wanted to email you to say thank you for giving me back, perhaps more than 15 years.

Best wishes
