Hi, thanks for the question .
is blotchy, brownish pigmentation on the sun exposed areas, especially face that develops slowly and fades with time. The pigmentation is due to overproduction of melanin
by the pigment cells, melanocytes. One should use proper sun screen, avoid harsh skin, change oral contraceptive
pills( some can cause measma). Other bleaching techniques are available , for which you must consult a cosmetologist/dermatologist
Have a healthy life !
