Tea Tree Olie

From piercings to pimples, Tea tree oil is truly an all-rounder. For pimples, I mark my pimple on dry and clean skin with a cotton swab every night (and morning). Because of the tea tree, it dries in and thus disappears like snow in the sun. My piercer also gave me the tip, if your piercing has a meat bump, to touch it 6 times a day with a toothpick with tea tree on it. This caused my meat bump to dry and slowly disappear.

Can you tell me if this product works great for black pimples?

I use the tea tree oil when I make my own body butter. It smells nice but it makes my skin nice and soft.
