Multi layered poly-L-lactic acid (PLLA) treatment of the face using a universal facial grid

A uniform model for the treatment of aging signs of the face using Poly-L-lactic acid is presented. The causes of aging effects on the levels of the bone, the connective tissue, fat pads and the skin are addressed in a single procedure by use of needle or canula. For the treatment of the skin, a facial grid is introduced in order to spread the product evenly and avoid the formation of nodules. This standardized procedure provides a safer treatment protocol in order to avoid adverse events such as nodules or irregularities.
