What are sunspots?
Imbalance of estrogen levels - the most common type for women is melasma. The formation of spots is first related to diseases in a woman's body and glands, such as the ovaries, breast, and pituitary gland, all of which are closely related because these organs secrete estrogen. Once these organs become diseased, the hormones in the body will lose balance, and this imbalance manifests on the face as the appearance of spots. This is more commonly seen in women who have been on contraceptives for a long time or suffer from pelvic inflammatory disease, uterine fibroids, etc.
Skincare products with high metal content - Some people use skincare products that contain high levels of chemical metals like lead and mercury or those with added fragrances over extended periods. These chemical components have light-absorbing properties and can easily cause dark patches on the skin. Additionally, some individuals are unaware that these products can spoil easily at high temperatures. They often leave their skincare products in the back seat of their cars when going out. After using spoiled products, their skin may itch, and exposure to sunlight can result in the appearance of spots.
