Dark circles are natural grooves under the eyes. When visible, they give a hollowed appearance to the gaze. Several factors can cause dark circles, the first being skin laxity. As the skin ages, it loses collagen and elastin, resulting in a loss of skin volume: the skin becomes less hydrated and conforms to the contours of the eye socket.
Other factors include fatigue and lifestyle habits. Additionally, genetics can play a significant role in the development of dark circles.
Depending on the causes, there are two main types of dark circles :
- Dark Circles : These can be caused by circulatory or pigmentary issues. The skin in this area is naturally thin, and in some people, blood vessels become more visible through the surface. Sometimes, they are due to dark pigmentation of the skin, which is often hereditary or ethnic.
- Hollow Circles : These can be hereditary or appear with age. The thinning of the skin exposes the orbital bone, causing dark circles to become more noticeable.
