Filler, also known as dermal filler or soft tissue filler, is a gel-like substance that is injected into the skin to restore volume, smooth out wrinkles, and enhance facial contours. It is commonly used in cosmetic procedures to address signs of aging or to enhance specific features.
The primary function of filler is to add volume and plump up areas of the face that have lost elasticity or have developed wrinkles and fine lines. It can be used to fill in deep lines, such as nasolabial folds (smile lines) or marionette lines, as well as to augment lips, cheeks, and chin. By replenishing lost volume, filler can help create a more youthful and rejuvenated appearance.
Filler is typically made from substances such as hyaluronic acid, calcium hydroxylapatite, or poly-L-lactic acid. These substances are biocompatible and can be gradually absorbed by the body over time. The effects of filler can last anywhere from several months to over a year, depending on the type of filler used and individual factors.
