Dr. Wang Xiaoyan
The causes of white spots on the skin of the back may vary, mainly including:
1. Skin diseases: such as pityriasis alba, tinea versicolor, and vitiligo. Pityriasis alba might be caused by malnutrition or vitamin deficiency; tinea versicolor is caused by Malassezia infection; vitiligo is associated with genetic factors, autoimmune conditions, and mental stress.
2. Environmental factors: prolonged exposure to sunlight and excessive ultraviolet radiation may lead to the appearance of white spots on the skin. In addition, environmental pollution may also affect skin health, causing white patches.
3. Other factors: pigment loss after trauma, senile leukoderma caused by skin aging, congenital non-pigmented nevi, and deficiencies in trace elements may also result in white spots on the back.
