Dark circles under the eyes, also known as periorbital hyperpigmentation, are a common cosmetic concern. They appear as dark, discoloured patches beneath the lower eyelids and can give the appearance of fatigue or aging. Several factors contribute to the development of dark circles, including:
- Genetics: A hereditary predisposition to thin or translucent skin under the eyes can lead to increased visibility of blood vessels and dark circles.
- Volume Loss: Loss of fat and collagen around the eyes as a result of aging can create hollow areas, casting shadows that contribute to the appearance of dark circles.
- Vascular Issues: Dilated blood vessels beneath the thin skin of the lower eyelids can result in a bluish or purplish tint, especially in individuals with fair skin tones.
- Lifestyle Factors: Lack of sleep, dehydration, excessive sun exposure, and poor dietary habits can exacerbate the appearance of dark circles.
