Please help me! I have really dark knees and I want to get rid of them. I don't wear shorts because its so embarrassing. I really want the be a cheerleader and the tryouts are in about a month. I really want to try out, but my knees just get in the way of that.can you please help ? I need something that will be cheap and will work really good. I've tried using limes but I haven't seen any results. Any other ways that will work fast?

It will be nearly impossible because it's all about how much skin you have around your knees. Some people's skin is all smooth and stretched out, and other's is sort of looser and bunched together. When looser, the pigment is more concentrated per square inch.
It's a fact of life that you just have to ignore.
No one will notice. I know cheerleaders tend to obsess over looking 'perfect' but if you don't, you will actually look better than the ones who fret.

There are no reliable skin lightening products on the market. Those that do produce results have very serious side effects, and most of them, while lightening your skin, will cause other issues that are even worse.

I'm sure it's not nearly as bad as you think it is. We're our own worst critics when it comes to flaws on our bodies, most people don't even notice the things we're self conscious about.
