A doctor has spent years in medical school and is qualified to respond to any complications. A beautician has no such training. Doctors study for years, understand patient psychology, are better able to understand the needs of their patients, and manage their expectations. Find a trained, qualified healthcare professional at BAAPS and BCAM. They will be registered with the General Medical Council and undergo frequent refresher training. Patient safety will be paramount.
Hyaluronic acid (HA) dermal fillers are the benchmark for temporary fillers. HA is naturally found in the body, so there is little chance of an adverse reaction, and it can be metabolised and disposed of naturally. With a permanent filler, the only way to get rid of it is to cut it out. HA can be dissolved with an injection of an enzyme called hyaluronidase. It is, therefore, easier to correct any problems, and HA degrades naturally within the body.
There are literally dozens of 'fillers' on the market in Europe. In the USA, by comparison, there are perhaps half a dozen approved for use. Always play safe and go with established, tried and tested brands such as the Juvederm range. Do not buy off the internet and do not self-inject!
As all procedures which involve a needle going into the skin carry some form of risk, you have to trust your practitioner to do it correctly, which is why it's so important to go to a trained professional. If you are trained to put the product in, you should be able to correct any complications arising.
A highly qualified Aesthetic Doctor has been treating many patients on a daily basis over many years, so they should know a thing or two about your treatment.
