Classifications and injection strategy for lip reshaping in Asians

Abstract

Filler injections have become very popular in recent decades. Of the various injection procedures, lip injection is an important aspect of filler injection, especially for Caucasian patients. Asians tend to have fuller lips than Caucasians, necessitating a different approach to lip injection. Classification systems for the lip for aesthetic treatment purposes can help a physician assess a patient accordingly, and a simple classification of Asian lips into four types for injection approaches is proposed in this paper. Each patient type is discussed in terms of trait and categorization, injection area, injection techniques, injection goals, and sample patients with treatment results.
