Hydroquinone
"I've use products with Hydroquinone for years. I am currently using a brand with 3%. I have a condition called Hyperpigmentation. When I bathe I slough off more skin than most people do. This product removes enough to give the impression that I have beautiful skin and I am often complimented on my skins softness and smoothness. I still have darkness under the arms but not unsightly. My knees, elbows are very dark and my hands are the darker especially the middle joint of each finger and my knuckles. All not unsightly because I use this cream. I am 60 have been mistaken for much younger. I avoid the sun."
