(enhancement or enlargement) is a term to describe procedures that affect a small change in the appearance of the lips.

Many different techniques are used to plump-up or fill-in the lips. One of those is lip augmentation by injection.

Injection techniques involve filling the lip with a substance like collagen or fat to create a fuller appearance.
Depending on the procedure and the extent of the brusing and swelling, you can expect to return to work either the same day or two to three days afterward
