I would like to know does hydronique work for medium dark colour skin or would it affect me? Or what kinds of bleaching cream would work for me for my body like knees, elbows, inner thighs??

Some people use it in alterations for example 2 weeks on and 2 weeks off, or 3 weeks on and 3 weeks off. From what I have heard it will continue to lighten the skin and will not get dark, and that you can use a more natural lightener during your weeks off from the Hq. You would have to exfoliate too.
