Objective: Most literature regarding lip augmentation refers to Caucasian anthropometric measurements, but ethnic differences affect facial dimensions and the evaluation of beauty. Specifically with regard to Asians and Hispanics, dermatology does not have much literature on the subject. This review investigates the differences in lip measurements and preferences of Asians and Hispanics compared with those of Caucasians. Design: A literature search of other fields, including plastic surgery, maxillofacial surgery, orthodontics, and forensic anthropology, was conducted, and relevant articles were selected that applied to the discussion of lip measurements and preferences in Asians and Hispanics. Results: Lip measurements do appear to differ between Asians, Hispanics, and Caucasians, and ethnic background appears to influence lip preferences. Conclusions: It is inappropriate to use Caucasian measurements and generalizations in lip preferences when determining what is "ideal" when aesthetically augmenting lips among Asians and Hispanics. Ultimately, it is important to take into account the goals, anatomy, and ethnic background of each individual patient before performing lip augmentation.
