The four main reasons for the formation of facial spots are as follows:

(1) Genetic reasons. Autosomal inheritance is the main cause of facial pigmentation. It usually starts in children around 5 years old, mostly in women, and is more severe in spring and summer and less severe in autumn and winter. Light brown to yellowish-brown pintip to rice grain-sized spots, symmetrically distributed on the face (especially the nose).

(2) Ultraviolet irradiation. Ultraviolet radiation in the sun is an important cause of the formation of facial spots, which is why sun protection is needed in summer. When the skin receives too much sunlight, the epidermis produces more melanin particles, which absorb ultraviolet rays and protect the body from damage. This is why everyone’s skin will turn darker after being exposed to the sun. Moreover, ultraviolet rays can cause chloasma and deepen the color of common facial spots.

(3) Endocrine reasons. Endocrine disorders are also an important reason for facial pigmentation in women. Changes in sex hormone levels during menstruation and pregnancy can affect the production of melanin. In addition, endocrine instability often leads to emotional instability, which can also indirectly cause the formation of facial spots

(4) Lifestyle issues. Bad lifestyle habits such as stress, partial eclipse, and lack of sleep can also increase melanin. People with unstable sleep schedules also have poor skin metabolism, which will affect the production of melanin particles.
