I know South Beach Skin solutions has a really good reputation, back when they started they gave out free samples too but I have NEVER tried it myself cause I didn't need to. My private parts including nipples were light bright pink but now as I'm aging (only 22) they're all getting brown :( I'm also considering South Beach. They have skin lightening gel for sensitive areas and it says it's for vagina, anal, genital, underarm, face, knees, elbows, scars. You might want to give it a try but keep in mind this is only a suggestion, I've never used it myself only heard people raving about it. Visit http://www.southbeachskinsolutions.com/
