Dermal fillers work by injecting a gel-like substance into the skin to add volume, restore contours, and smooth out wrinkles and fine lines. The gel typically contains a substance such as hyaluronic acid, calcium hydroxylapatite, or poly-L-lactic acid, which helps to stimulate collagen production and improve skin texture and tone. During the treatment, the practitioner will use a fine needle or cannula to inject the filler into the targeted areas of the face. The injection sites are typically numbed with a local anesthetic to minimize discomfort.

Once injected, the filler binds with water molecules in the skin to create a plumping effect, which smooths out wrinkles and adds volume to the treated area. The results of dermal fillers are typically visible after the treatment, and can last anywhere from six months to two years, depending on the type of filler used and the individual's metabolism. Over time, the filler is gradually absorbed by the body, and the effects will gradually fade. Dermal fillers can be used to treat a wide range of cosmetic concerns, including wrinkles, fine lines, hollows under the eyes, thinning lips, and sagging cheeks. They offer a non-surgical solution for facial rejuvenation, with minimal downtime and natural-looking results.
