In order to eliminate traces, we must pay attention to sun protection. If the sun protection is not done well, it is very likely that the white spots will turn black.
Secondly, we must pay attention to daily hydration. Only when the water is replenished can the melanin on the face be eliminated and will not precipitate on the traces.
Diet is also critical. Usually, we must try to avoid basking in the sun after eating sensitive food, otherwise it will easily lead to pigmentation on the face, and it is difficult for white marks and red marks to disappear. Photosensitive foods include carrots and celery.
