What is melasma?

Increase In  Facial Blood Vessels

Due to excessive exposure to UV rays from the sun, the blood vessels in your face tend to enlarge, and this symptom is also present among the melasma patients. The main reason behind the enlargement and increase of blood vessels is that the UV rays tear off the upper layer of our skin, and then there is the appearance of more blood vessels in that area of skin. The symptom of an increase in blood vessels is due to the prolonged exposure to sunlight, so this symptom is less common in the winter days.
