The "Holistic Individualized Treatment" (HIT) approach is used to identify treatment priorities, focus areas, and appropriate products for soft tissue filler treatments.

The "Kiss and Smile HIT" considers lip volume, lip framing and expression to improve patients appearance. This trial will assess the effectiveness of the Kiss and Smile HIT algorithm in treating patients with different kiss and smile related issues (e.g. volume loss, lips lack proper framing, lack of a confident smile due to issues with expression).
