Facial fillers are substances injected into the skin to smooth wrinkles and make them less noticeable. Injection of a facial filler is generally an outpatient procedure that's done with numbing medication. The procedure takes up to an hour.
You might have mild discomfort, bruising and swelling for up to a week. After the swelling goes down, you might need a touch-up injection for best results. How long the effect lasts depends on the type of wrinkle and filler, among other factors.
Facial fillers, or soft tissue fillers, generally aren't used for people who have suppressed immune systems or who take blood-thinning medications (anticoagulants).
Types of facial fillers
Facial fillers include:
-
Hyaluronic acid (Restylane, Juvederm, others). This natural component of the skin's connective tissue is the most common filler used for wrinkles. The results typically last 6 to 12 months.
-
Calcium hydroxylapatite (Radiesse). This filler is used to contour the jaw line, restore volume in the cheeks, and treat deeper wrinkles and skin folds. The results last up to a year when used for contouring and 3 years when used to fill wrinkles.
-
Fat grafting. With this method, fat is removed from the lower abdomen or other area through liposuction. It is then injected through small incisions into the cheek, temple, lips or forehead. The effects might be permanent. But achieving the desired results usually requires more than one session as well as overfilling the site because the body reabsorbs some of the fat.
-
Permanent soft tissue filler (Bellafill). This filler is used to smooth deep wrinkles around the mouth. The body can't absorb this type of filler, so it doesn't require reinjection. Permanent soft tissue filler generally isn't recommended as a first-time facial filler treatment.
-
Poly-L-lactic acid (Sculptra). This product is used to restore facial volume lost due to aging or illness. Two or three sessions are usually required. The effects last up to two years.
