Age
Effects of Aging on Dark Circles Under the Eyes
As individuals age, they often develop larger and more prominent dark circles under their eyes. This occurrence can be attributed to the natural loss of collagen, which causes the skin to become thinner and slightly transparent. Consequently, older individuals are more prone to breaking blood vessels when they rub or touch their eyes. Additionally, the presence of prominent skin folds or wrinkles can further accentuate the appearance of dark circles under the eyes.
Ethnicity
Exploring the Relationship between Ethnicity and Dark Circles Under the Eyes
Dark circles under the eyes can be attributed to various factors, and one lesser-known cause is ethnicity. While these circles can affect individuals of all skin colors, a 2014 study revealed that they tend to occur more frequently in people of color. Researchers have theorized that this disparity is linked to variations in melanin levels across different ethnicities.
It is widely known that melanin, the pigment responsible for determining skin color, plays a crucial role in shielding the skin from the harmful effects of the sun. However, individuals with darker skin tones naturally possess higher levels of eumelanin, a specific type of melanin that provides superior protection from UV radiation. While this is advantageous in terms of sun protection, it may also contribute to a greater likelihood of developing and displaying dark circles under the eyes.
The exact mechanism behind the association between ethnicity and dark circles remains unclear. However, it is believed that the higher concentration of eumelanin in darker-skinned individuals could lead to hyperpigmentation in the under-eye area, making the dark circles more prominent and noticeable.
While ethnicity is just one factor among many that can contribute to the development of dark circles under the eyes, understanding this relationship can help individuals of all ethnic backgrounds better address and manage this common cosmetic concern.
