The trend for enlarged lips has been popularized by media and social media. The lips have considerable aesthetic and functional importance, in addition to having a complex anatomy. Serious complications, including vascular compromise or occlusion leading to cutaneous necrosis and blindness, can occur as the result of lip enhancement using dermal fillers. Therefore, aesthetic practitioners require an in-depth understanding of the anatomy and vasculature of the lips and the perioral area prior to providing lip enhancement using dermal fillers.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objectives<\/jats:title><jats:p>This literature review aimed to summarize existing data describing the origin, path, and depth of the superior and
