First of all, we should judge what disease caused the spots on the face. There are several possibilities: 1, freckles usually exist since childhood, but the color deepens after sun exposure; 2. Chloasma, also known as butterfly spot, is caused by many reasons, most of which are related to endocrine, especially estrogen level, irregular menstruation, pregnancy, taking birth control pills or poor liver function, chronic kidney disease and so on. In addition, sun exposure and mental factors will also aggravate the condition. In either case, the treatment should first be sun protection, because sun exposure will aggravate the color of the spots. If it is freckles, you can use ruby laser to remove the existing freckles. Generally, there will be no scars, but some people will have very shallow marks, so you should consult your doctor carefully before making a decision. If chloasma is diagnosed, laser is ineffective, but it needs both internal and external repair, and you should be happy, otherwise it will interfere with endocrine and aggravate the condition. Regular freckle removing products are effective for mild freckles and chloasma. I suggest you go to the plastic surgery department of the hospital, or you can use laser to remove spots. The doctor will take reasonable and effective treatment measures for you according to your situation.
