Dermal fillers have been around for centuries, but have been approved for use in the United States for 30 years. The FDA initially approved it for the treatment of various problems with face and eye cramps.
The scientific name for botox, a dermal filler, is botulinum toxin type A. It is a purified neurotoxin made by fermentation of the bacterium Clostridium botulinum. It is diluted and injected. You can look for botox certification course online.

Dysport, which is also another injectable agent, is known as abobotulin type A toxin. It is a neurotoxin derived from Clostridium botulinum which acts like any other bulking agent.
How does it work?
It is a neurotoxin, which means paralysis. This blocks signals telling your muscles to contract. When you negotiate it, your skin folds or tucks, and when these movements are frequent enough, wrinkles appear. Stopping contractions slows down wrinkles.
By injecting this formulation into areas of your face, you immobilize those small areas to reduce the movement of your skin and, therefore, reduce wrinkles drastically.
This is temporary paralysis because even when the active ingredients are metabolized, the effect is lost. These injections are expected to last four to six months. Additional doses are usually required at this time.
However, it has been found that over time your muscles may be trained so they move less and you are happy not to wrinkle for long periods of time. They help to accentuate your skin by dealing with wrinkles and sunken areas on your face.
