Nasolabial filler is a temporary cosmetic procedure targeting the face, specifically addressing the nasolabial region. This area is defined by lines running from both sides of the nose down to the lip edges, encompassing the space between the nose and chin, including the inner cheek and lip border. The treatment is named after this specific region where the filler is applied. Aging is the primary factor behind the development of nasolabial lines; however, an individual’s genetic makeup also influences when these lines appear, their depth, and other characteristics.
