How To Get Rid The Dark Color In The Labia Minora And Under Arms?

My labia minora and private part has become very dark. I did find a product that can store my pinkness (an actual brand) but, I forgot where i got the information from (so i'm still searching. sigh). I don't know what to do. also, my labia minora is a bit longer. I dunno how to cut them, so they find well, instead of me tucking them in. I am still a virgin. why is this happening. even, my underarms are dark. but i shave anyway.
