Researchers have identified four key bio-markers that shape perceptions of attractiveness: symmetry, hormones, senescence, and carotenoid pigmentation.

Deeply rooted in biology, our sense of what is physically appealing, and what is not, evolved over thousands of generations of human history. Although the concept of beauty may seem subjective—the eye of the beholder and all that—our perceptions of, were shaped in part by natural selection in response to important cues that signal health, vitality, and reproductive fitness. When we find a face attractive, we are unconsciously assessing it for signs of health and genetic fitness..
Over time, human brains may have evolved to prefer symmetrical faces because these preferences increased the chances of choosing a healthy, fertile mate. This preference for symmetry could be an evolutionary adaptation that enhances reproductive success.play a pivotal role in shaping our facial features, and thus, our attractiveness. The two most commonly implicated hormones in this context are estrogen and testosterone.
Research shows that cues to youthfulness, such as large eyes and a smooth forehead, are often associated with neoteny. Such features are attractive because they signal that an individual is in their reproductive prime. Therefore, maintaining a youthful appearance can enhance one's attractiveness by signaling health and fertility.Other indicators of age include skin quality, wrinkle formation, and the overall texture and elasticity of the skin.
Individuals with higher levels of carotenoids in their diet tend to have a slight yellowish tint to their skin, which is perceived as healthy and attractive. If you've got a lot of carotenoids—in fact, excess carotenoids—you put the extras in your skin. A healthy gut is necessary to be able to absorb carotenoids. Thus, the yellowness in all skin, no matter if it is light or dark, is a marker of carotenoids which indicates good gut health.
