Best remedy for rid of acne and scars

I had clear skin during teenager. But Since started working, had acne issues and got worst. Then I came across with this Tea Tree Oil. I applied this on acne and scar area every night before sleeping. Within 3-4 months it got cured and totally vanished the scars too. Now I immediately apply it, whenever acne pops out. It will disappear within 3 days without any scars.
