Because of their ability to relax muscles, these injectables are useful where overactivity of muscle groups cause unwanted skin lines such as:
- Frown lines
- Crows feet
- Bunny or Wolf Lines
- Platysmal or neck bands
It may also be used to prolong the effects of dermal fillers which would be "squeezed" out prematurely in areas such as:
- Marionette lines
- Chin crease
What is involved?
Tiny amounts are injected in and around the area. There is a stinging sensation with the procedure, which is very short lived. The procedure itself usually takes less than 10 minutes. Within a few days the effects start to become noticeable, although the peak of action may not occur for 1 to 2 weeks.
Over a period of 3 to 4 months the effects gradually wear off and to continue the effect, repeat injections are required. Repeat injections over time may lead to longer intervals between treatments, but it is unlikely that it will ever be permanent.
Does it work for everyone?
No. About 2 of patients have pre-existing antibodies which renders the substance ineffective. Unfortunately there is no way of identifying this small group of people beforehand.
What are the risks?
General after effects:
- Bruising. This is temporary only
- Pain or headache. This passes quickly
Upper face injections:
- Ptosis or weakness of the upper eyelid. This causes drooping of the eyelid and occurs in 1 to 2% of patients. This may last up to two weeks but is minimised by not lying down for 4 hours after treatment.
- Double vision. This is very uncommon but will usually disappear within two weeks.
"Bags" under the eye. May appear more prominent in susceptible persons.
- Neck weakness (where injected into platysmal bands)
- Difficulty with swallowing, whistling and speaking (around mouth)
- Asymmetrical smile (treatments around mouth)
This is not recommended for:
- Pregnant or breastfeeding women
- Patients with Multiple Sclerosis or Myasthenia gravis
