Hello, I am a young woman of east indian descent with dark brown skin that is extremely uneven. I don't have the time to spend loads of cash on skin lightening treatments, and I am only trying to lighten certain parts of my body, specifically the skin around my mouth, underarms, elbows and knees, all of which are significantly darker than the skin around them. However, I don't want to treat the skin and find it lighter than what it should be. Is there a cheap and natural way to lighten and brighten that skin without making it too light? I have heard lemon juice and milk works well, but I am not sure of the best way to use it. Any ideas?
