What Is Lip Filler?
Lip filler is an injectable gel made of hyaluronic acid, a sugar molecule the skin already produces to bind water and hold volume. The injectable form is cross-linked, so the molecules stay bonded and the gel keeps its shape under the lip tissue. Placed in the body of the lip, it builds height and fullness. Placed along the vermillion border, it sharpens the outline of the lip. The gels used for lip work are the RHA family and Restylane-L, and the body breaks them down over six to twelve months.
