Sudden growth of spots on the face may be related to endocrine disorders, hereditary factors, long-term exposure to ultraviolet rays or the use of poor-quality cosmetics, etc. It is commonly seen in chloasma, freckles and other facial pigmented spots. 1. Endocrine disorders: when women are in pregnancy or after taking contraceptive pills, it will lead to endocrine disorders, such as excessive secretion of oestrogen to stimulate melanin cells, so that melanin will increase and chloasma will grow on the face. 2. Genetic factors: Freckles are common in girls around 6 years old. With the growth of age, freckles will continue to increase. 3. Long-term exposure to ultraviolet rays: Ultraviolet rays do great harm to human skin. People who have been exposed to ultraviolet rays for a long time will have their melanin cells stimulated, and brown spots, such as seborrheic keratosis, will easily grow on their faces. 4. Long-term use of poor-quality cosmetics: If you use poor-quality cosmetics for a long time, your face will suddenly grow spots, such as chloasma. Staying up late for a long time, poor sleep quality, and often consuming spicy and stimulating food will also lead to spots on the face. If you want to get rid of color spots on your face, you should first change your bad lifestyle, go to bed early and get up early, eat healthy and avoid sunshine. If you want to get rid of spots quickly, it is recommended to go to the cosmetology department of regular hospitals for laser spot removal.
