Dermal fillers are typically composed of various substances, including hyaluronic acid, calcium hydroxyapatite, poly-L-lactic acid, or polymethylmethacrylate (PMMA). Each filler type has its own unique properties and indications for use.
Hyaluronic acid (HA) fillers are the most used type of filler. HA is a natural substance found in the body that helps maintain moisture and volume in the skin. These fillers can be used to add volume to the lips, cheeks, and nasolabial folds (lines that run from the nose to the corners of the mouth), as well as to smooth out wrinkles and fine lines.
Calcium hydroxyapatite fillers are composed of microscopic particles suspended in a gel. They can be used to fill in deeper wrinkles, such as nasolabial folds, and to restore volume in areas like the cheeks. They also stimulate collagen production, providing longer-lasting results.
Poly-L-lactic acid (PLLA) fillers are biocompatible and biodegradable. They work by stimulating collagen production over time, resulting in gradual and natural-looking volume restoration. PLLA fillers are often used to treat larger areas of facial volume loss, such as hollow cheeks and temples.
Polymethylmethacrylate (PMMA) is a synthetic substance mixed with collagen. It is used in certain fillers to provide long-lasting results by creating a supportive framework in the skin. PMMA fillers are typically used for deep wrinkles and facial sculpting.
The choice of filler depends on factors such as the specific area being treated, the desired outcome, the duration of results, and the individual’s preferences. It is important to consult with a qualified healthcare professional or dermatologist who can assess your specific needs and recommend the most appropriate filler for you.
