There are generally two types of fillers.

• Synthetic and natural. Synthetic fillers include materials such as silicone, hydroxyapatite, and PMMA. 
• Natural fillers include collagen, hyaluronic acid, and body fat. Silicone, for example, is a synthetic filler that has been used for decades in various medical applications. It is a permanent filler that is injected into the body, but it can cause complications such as infection, inflammation, or even migration to other parts of the body. 
• Natural fillers such as hyaluronic acid and collagen are temporary and eventually absorbed by the body.

Fillers offer many benefits, but they also come with risks. 

• Risks Infection and inflammation at the injection site. This can occur if the injection is not given under sterile conditions or if the patient has a medical condition that puts them at greater risk of infection.
• Risks of an allergic reaction to the filler. This can appear as redness, swelling, and itching at the injection site. In rare cases, it can lead to a more serious reaction, such as anaphylaxis. 
• The movement of the injected filler to other parts of the body is a risk. This can happen if the injection is not done correctly or the filler material is incompatible with the patient’s body.
