Is it wrong to buy whitening cream for this reason?/how do I make my skin color match?

So my face is light caramel while my whole body is brown, I think this happend because I drink a lot of water and use facial cleansers. The problem is that when I use foundation my face looks very light like whiteish. So would it be wrong if I used cream to even everything out? The last thing I can think of is getting a tan on my face but that rarely works out, I'll always stay the same shade of brown and even if my face did get darker it would get lighter in the winter and lighter when I clean it.

Is their any other products that
isn't whitening that I can use? And do you think that I'll get in trouble with the cashier for buying whitening since im 15?
