There are several types of fillers available, including hyaluronic acid (HA) fillers, calcium hydroxylapatite (CaHA) fillers, and poly-L-lactic acid (PLLA) fillers. HA fillers are the most commonly used type of filler and work by adding volume to the skin and attracting water molecules, which can help plump and hydrate the skin.

The filler injection process involves using a fine needle to inject the filler substance into the targeted area. The procedure is relatively quick and typically takes only a few minutes to complete. The results of filler injections are immediate, but may take a few days to fully settle.

Fillers typically last for several months to a year, after which the effects gradually wear off and the filler is naturally absorbed by the body. The treatment can be repeated as needed to maintain the desired results.

Fillers are generally safe when performed by a qualified medical professional, but may cause some side effects, including temporary bruising, redness, and swelling at the injection site. In rare cases, more serious side effects may occur, including infection and allergic reactions. It is important to discuss the potential risks and benefits of fillers with a qualified medical professional before undergoing the procedure.
