My face suddenly started losing its pigment in spots all over my face. There is some peeling and irritation. What's going on and how can I fix it?

LOSING PIGMENT FACE. WHAT DOES SUDDENLY MEAN? WEEKS? MONTHS? WITHOUT ACTUALLY SEEING YOUR PROBLEM, THERE IS NO WAY I CAN HELP YOU. I SUGGEST YOU SEE A DERMATOLOGIST. BEST LUCK . . .
