Attractiveness of eyebrow position and shape in females depends on the age of the beholder

Background Great diversity exists among individuals with respect to eyebrow position and shape, and the notion of an "ideal" eyebrow has changed quite significantly over the past several decades. Methods This study compared three different variations of eyebrows. One variation was the arched eyebrow with the maximum height in the middle. The other two variations had their maximum height in the lateral third, but differed in their position (high vs low). For each of the seven female portraits presented, three variations were generated using morphing software. A total of 357 subjects 12 to 85 years of age compared these variations and ranked each woman individually with respect to perceived attractiveness. Results The data show that the preference for a specific eyebrow shape depends on a person's age. Young subjects up to 30 years of age preferred eyebrows in a lower position, and ruled out arched eyebrows. Subjects older than 50 years stated exactly the opposite preference. Conclusion First, there is not one single beauty ideal for eyebrows, but at least three. The ideal a person prefers depends on his or her age. Second, because trends are generally introduced by young people and not by older individuals, and the young tend to prefer eyebrows in a lower position, it seems plausible to assume that the trend currently appears to be moving away from arched eyebrows toward lower positioned eyebrows with a maximum height in the lateral third
