When people are in the menstrual cycle, the hormone level in the body is in a stable decline stage, and chloasma is less disturbed by hormones and will become lighter.

Chloasma, also known as butterfly spot, is the most common pigmented skin disease in women. Because it is born on the face and has a large area, it has troubled many women who love beauty. Dermatologists have found that the occurrence of this disease is mostly related to endocrine dysfunction (such as pregnancy, menstrual disorders, ovarian and uterine lesions, etc.). ). Especially when the courtship is unbalanced, it is most likely to get sick, and it is most common in reproductive activities, such as pregnancy for 3-5 months and oral contraceptives 1-20 months. In addition, during menopause or suffering from reproductive diseases, estrogen and progesterone increase and become colored, so that tyrosinase is inhibited by glutathione, which leads to an increase in melanin. At the same time, strong sunlight, stimulation of inferior cosmetics, chronic diseases such as liver disease and visceral tumor, long-term malnutrition and lack of vitamins A, C or nicotine are all possible causes of this disease. Moreover, the long-term lack of glutathione in the diet can also increase the activity of tyrosinase in the skin, so that tyrosine can form dopachrome under the action of tyrosinase, and then oxidized into dopachrome, forming melanin and inducing diseases.

It is recommended to eat more foods rich in vitamin C, such as oranges, tomatoes, tender peppers and radishes. Invid C can inhibit the oxidation of dopaquinone in skin, make dark oxidized pigment fade, and then inhibit the formation of melanin.

It is recommended to eat fresh lettuce, egg yolk, sesame seeds, chaff and other foods rich in vitamin E. With the increase of age, lipid peroxide in the body gradually increases, which is easy to induce melanosis. Vitamin E has antioxidant effect and can effectively inhibit the production of lipid peroxide.

In addition, we should try to avoid strong direct sunlight, eat less foods with darker pigments such as soy sauce and coffee, and do not use hormone ointment and irritating cosmetics to minimize the occurrence of chloasma and keep the face white and plump.
