1, reason:
Spots: First, genetic factors. In some women, because the pigment in the plaque matrix contained by hormones is higher than that of ordinary people, there are many spots, which are particularly obvious. Second, the influence of ultraviolet rays. A person who likes to jump outside or bask in the sun has more spots on his body than others and is prone to spots in summer.
Nevus: it can be caused by many reasons, and it is still inconclusive. It is generally believed that the occurrence of nevus is related to genetic factors and environmental factors dominated by ultraviolet rays.
2, common and symptoms:
Spots: Spots may be chloasma, freckles, melanosis, nevus pigmentosum, nevus OTA, tattoos, etc.
Nevus: can be complicated with infection. Most of them grow slowly, or remain unchanged for many years, but spontaneous degradation rarely occurs. Individual types of moles may become malignant, thus endangering life safety.
3. Preventive measures:
Freckle removal: The basic method is to avoid sun exposure and minimize ultraviolet radiation.
Mole:? Eat more fruits and vegetables, don't be exposed to the sun, pay attention to clean the skin and pay attention to personal hygiene.
