How can i use tea tree oil to remove spots.?

I am 18 years old (male) and i have a few spots on my face which i hate. It embarres me to approach any one new or even speak to females in the fear that i will just get ignored. I have tried several face scrubs and washes. I have also tried several spot creams and they don't work. I have heard about tea tree oil but no sur how to use it to remove spots. If any one has any other suggestions that will remove spots asap i am open to new things. Thanks
