Quantitative and Objective Measurements of Facial Aging Process with Anatomical Landmarks.

A reliable and readily available way to quantify slight changes in facial characteristics are coveted and sought after in the recent decade. [1,2,3] The facial aging process is associated with the attenuation of retaining ligaments and the laxity of soft tissue.[4,5] To quantify facial rejuvenation on the basis of aging, we provide four angular and six linear measurements between static and mobile points to assess subtle changes before and after rejuvenation procedures.
