Composition
Dermal fillers are typically made of various substances, including hyaluronic acid, calcium hydroxylapatite, poly-L-lactic acid, or polymethylmethacrylate microspheres. Hyaluronic acid-based fillers are the most commonly used and are known for their biocompatibility and ability to attract and retain moisture, providing a plumping effect.
Purpose
Dermal fillers are primarily used to restore volume and smooth out wrinkles or folds in the skin. They can be used to diminish fine lines around the mouth, nasolabial folds (smile lines), marionette lines, hollow under-eye areas, and to add volume to the cheeks, lips, and temples. Fillers can also be used for non-surgical nose reshaping or chin augmentation.
Procedure
The administration of dermal fillers involves an in-office procedure performed by a trained dermatologist or healthcare professional. Before the procedure, the treatment area may be numbed with a topical anesthetic or a local anesthetic injection to minimize discomfort. The filler is then injected strategically into the targeted areas using a fine needle or cannula. The procedure is relatively quick, typically taking about 15-30 minutes.
Results and Duration
The effects of dermal fillers are visible immediately after the treatment, but optimal results may take a few days to settle. The duration of the results depends on the type of filler used, the treated area, and individual factors. Hyaluronic acid fillers generally provide temporary results that can last from 6 to 18 months, depending on the specific product. Other fillers may offer longer-lasting results, ranging from several months to a few years.
Safety and Side Effects
Dermal fillers are considered safe when administered by trained professionals. However, as with any cosmetic procedure, there are potential side effects, which are typically mild and temporary. These may include redness, swelling, bruising, tenderness, or itching at the injection sites. Serious complications are rare but can include infection, allergic reactions, or vascular occlusion if the filler is mistakenly injected into a blood vessel.
