Solutions/creams for dark elbows?

[Claymorekick]

Does anyone have any recommendations for how to improve dark elbows? Mine are really obvious and I'm really self conscious of them in the summer when I can't hide them in long sleeves.

Have googled but it has produced different creams/home-made solutions but don't want to waste money on stuff that doesn't work. So I want tried and tested solutions

i can hand on heart say I have never noticed the tone of anyones elbows but if it bother you the old 'lemon juice' trick might work i suppose

I have had a couple of comments - not malicious ones, just people asking what was wrong with my elbows - so people do notice.

What is the lemon juice trick?
