I always cring under the lighting in the fitting room of Adidas. All the dark spots on my back and arms come dead obvious. Erm, they resemble white spots patches but only differ in color. They are only apparent in areas not exposed to the sun since I never leave home in sleeveless tops. I'm aware that exfoliation helps but despite scrubbing everyday, these spots dun seem to come off? Is there anything else I shld do?

thanks!
