Facial spots are often related to heredity, hormone, environment and lifestyle. 1. Heredity: Facial spots are hereditary to a certain extent, and if there are still patients with facial spots among their family members, it is considered to be related to heredity. 2. Hormone: Long-term hormone level disorders in the body or long-term use of glucocorticoids, progesterone and other hormonal drugs can also easily lead to facial skin spots. 3. Environment: Facial skin is often irradiated by sunlight, which can easily lead to increased melanin production on the skin surface, resulting in facial spots. This kind of patients’ facial spots mostly aggravate in spring and summer, and reduce in fall and winter. 4. Lifestyle: Excessive mental stress, lack of sleep, partial feeding, using improper cosmetics and other bad habits can easily lead to an increase in melanin formation on the skin, resulting in spots on the face. When spots appear on the face, it is recommended to go to a regular hospital to find out the cause and treat it under the doctor’s guidance.
