[|Human|] HEllo Dr. my name is Muneer. I consulted so many dermatologists but in vain. Some say my pigmentation is due to excessive exposure to sun. Some say they are ephilids. I have read about the freckles and ephilids. there in duration increases in summer and decreases in winter, but i feel no change in summer as well as winter. please provide me the proper advice and remedy.
[|AI|]  Hello, Thanks for writing your query to us. Freckles are clusters of concentrated melanin which are often visible in fair skin people. It is genetic in origin. Formation of freckles is triggered by sunlight. So it is not related to weather. It is basically the exposure to sunlight that means exposure to UV B light that activates the melanocytes to increase melanin production which makes freckles darker & make them more visible. Take care.
