What Makes You Physically Attractive? 5 Things You Probably Didn't Know.

So we all know facial symmetry is important to be considered good-looking. True: It is an important factor but it is not everything. Far from it. Actors like Ryan Gosling and Paul Walker defy this rule. Instead there are subtle and not so subtle factors that are important or crucial for physical attractiveness.

Find out: Five things you may not know about that make face attractive.

1. Limbal rings

This is a ridiculously small difference, but look closely. The dark ring that separates the iris from the white of the eye (sclera) is the limbal ring. Studies have shown that in images where only this feature has been altered, almost all participants prefer the image with the darker limbal ring. It is a sign of youthfulness and virility, so it is an very attractive trait.

2. The distance between your eyes

It should be one eye length. Less than that, and it is close-set (hypotelorism). This can cause an untrusthworthy or primitive look, more than that and it is wide-set (hypertelorism). Generally speaking, wide-set eyes can be attractive in females to a point. For example, Jacqueline Kennedy had this feature.

3. The shape and position of your upper lip

It should be roughly 63-70% of the height of the lower lip, with two defined peaks and an indentation in the middle (cupid's bow). Somewhat full lips are actually preferred in both sexes. The skin above the upper lip (philtrum) should also be relatively short, 13-15mm in women and 15-18mm in men.

4. Skin colouration

We all know the skin is important but now many people know that what can make skin very attractive is related to diet! While many people go tanning to get darker skin, it has shown in studies that by eating certain food we can get a healthy glow. This is preferred even to a tan! Eating carrots and tomatoes introduce ß-carotene and asthaxanthin in the body, which has this effect

5. Lower eyelids

The lower eyelids have been dubbed the seat of youth and the seat of beauty by some scientists. A strong, straight lower eyelid indicates great bone support and youthful appearance. It is crucial to be good-looking.

These are five important factors in the consideration of an attractive face.
