Why Does the Skin Become Darker?

Skin darkening is primarily caused by an increase in melanin. Melanin is produced by melanocytes in the skin and functions to absorb ultraviolet (UV) radiation and protect the skin from UV damage. When the skin is exposed to UV radiation, hormonal changes, inflammation, or other stimuli, melanocytes increase melanin production, resulting in darker skin coloration. Additionally, genetic factors, endocrine disorders, side effects of certain medications, and unhealthy lifestyle habits may also contribute to skin darkening.

To improve skin darkening, it is recommended to avoid prolonged sun exposure. When outdoors, apply a high SPF sunscreen, wear a hat, or use an umbrella to reduce UV damage to the skin. Maintain good sleep habits and ensure adequate rest, avoiding late nights, as sleep deprivation can burden the skin and lead to a dull complexion. Regarding diet, consume foods rich in vitamins C and E, such as fresh fruits, vegetables, and nuts, which help combat oxidation and inhibit melanin formation. Engage in moderate physical activity to promote blood circulation and improve the skin's blood supply. If skin darkening persists or is accompanied by other discomforts, it is advisable to consult a physician promptly.
