The Ideal Eyebrow: Lessons Learnt From the Literature.

The concept of facial aesthetic has been around for centuries, popularised in the Renaissance period by artists such as Da Vinci. The eyebrow is also known as the master line of the face and is used as a reference for other facial angels and contours. The criterion of the aesthetically pleasing eyebrow has been a subject of much debate over the years, ever since make-up artists such as Westmore described the modern concept of the ideal brow in the 1970s. The concept of the ideal brow has evolved over the decades, subjected to influence by cultural trends and differences. This narrative review aims to examine the current evidence in the literature with regard to the ideal eyebrow from an aesthetic point of view, taking into account gender, age and ethnic differences. A set of guidelines are also proposed in order to help clinicians tailor the appearance of the eyebrow to individual patients based on the author's personal opinion.Level of Evidence V This journal requires that authors assign a level of evidence to each article.
