Secondly, the body is exposed to sunlight, the formation of melanin in the skin is increased, and the skin color of the human body is better. Usually vitiligo occurs in spring and summer, a small number of patients after exposure to disease, this is because the sun's short wave ultraviolet can make depigmentation; and long wave ultraviolet will accelerate the metabolism of melanin. Long term exposure to ultraviolet radiation, it is easy to lead to the emergence of vitiligo.

Finally: mental factors can also lead to vitiligo. If the spirit is too anxious, the body will secrete a lot of adrenaline, will consume a lot of tyrosine, tyrosine is one of the substances that produce melanin, so it can affect the production of melanin, induce vitiligo.
