Skin fillers, more accurately known as dermal fillers, are medical device implants approved by the FDA to help create a smoother and/or fuller appearance in the face. They are also referred to as injectable implants, soft tissue fillers, lip and facial fillers, or wrinkle fillers.
In essence, dermal fillers are substances injected into the skin to:
- Smooth wrinkles and fine lines: They can reduce the appearance of wrinkles around the mouth, eyes, and forehead.
- Restore volume loss: As we age, we lose collagen and elastin, leading to volume loss in the face. Fillers can restore this volume in areas like the cheeks, temples, and under-eye area.
- Enhance facial contours: Fillers can be used to augment the lips, define the jawline, and improve the overall shape of the face.
- Improve the appearance of scars: Certain types of fillers can help to fill in depressed scars.
Different types of dermal fillers exist, each with its own properties and duration of effect. Common types include:
- Hyaluronic acid (HA) fillers: This is the most common type of filler. HA is a naturally occurring substance in the skin that helps keep it hydrated and plump. HA fillers are temporary, typically lasting from 6 to 18 months.
- Calcium hydroxylapatite (CaHA) fillers: These fillers are made of a mineral-like compound found in human bones. They are longer-lasting than HA fillers, typically lasting up to 12-18 months.
- Poly-L-lactic acid (PLLA) fillers: PLLA is a synthetic substance that stimulates the body's own collagen production. The results appear gradually over several months and can last for up to two years or more.
- Polymethylmethacrylate (PMMA) fillers: These fillers contain tiny, permanent microspheres that provide support and structure to the skin. They are often used to treat deep wrinkles and folds.
It's crucial to consult with a qualified and experienced healthcare professional to determine the best type of filler for your specific needs and goals, as well as to understand the potential risks and benefits of the procedure.
