Can bad mood make your skin darker?
Generally speaking, a bad mood does not directly cause the skin to darken. The detailed explanation is as follows:
Skin color is primarily determined by melanin in the skin. Melanin is produced by melanocytes located mainly in the basal layer of the epidermis. Melanin production is primarily influenced by genetic factors and ultraviolet (UV) radiation, rather than emotional state. UV exposure is one of the main causes of skin darkening. When skin is exposed to sunlight, UV rays stimulate melanocytes to produce more melanin, resulting in darker skin. Therefore, prolonged sun exposure without proper protection can gradually lead to skin darkening. Additionally, poor circulation and inadequate oxygen supply may contribute to dull, lackluster skin.
In summary, skin darkening is mainly caused by UV exposure and other external factors. While maintaining a positive mood does not directly affect skin color, it promotes overall physical health and helps maintain healthy, radiant skin.
