What Are Lip Fillers?
Lip fillers are injectable substances formulated with hyaluronic acid (HA), a naturally occurring compound found in the human body. HA is responsible for the supple, hydrated contours in youthful skin and, when injected, can help your lips look fuller and more defined. Lip injections take just minutes to complete and make an excellent alternative to fat transfer, a lip lift, or implants. Results typically last 6 to 18 months.
