I didn't know tea tree oil for acne can be used for acne until now. All the while, I use tea tree oil for washing my face, moisturing and even in my bath.
I think age is catching up with me. I somehow love natural products and do not mind the smell of certain ingredients. I have been buying a lot of organic soaps and oils and though they don't smell as sweet, I find them so much more comforting than fake fragrances.
So, if you are looking for something natural and do not want fake chemicals, try tea tree oil.
