I bought tea tree oil and have been using it in handling slight cutting/wounds on my fingers and toes to avoid infection like paronychia. It’s very effective as a home remedy to treat little problems that are slight cuttings and skin problems like acne and psoriasis. But tea tree oil is a very strong irritative oil that would be harmful to delicate part of the skin like face and membrane. This is to tell about tea tree oil’s irritation property: I ever tried to save a gecko from a cockroach house, the gecko was stuck onto the adhesive board firmly. I happened to have a bottle of tea tree oil and considered such a oil is a dissolution to the chemical adhesive. So I applied tea tree oil to the gecko and the adhesive, the gecko detached from the adhesive right away and died right away! (Really sorry for that!) Gecko’s skin is very delicate compared with human’s. I believe it’s because tea tree oil’s strong property of irritation and volatile, the oil penetrate the gecko’s delicate skin and “take action” in its blood circulation quickly.

So we can see tea tree oil is good but we need to use it carefully. The below is the suggestion use printed on the label of country life tea tree oil:
Add one or two drops to a moist cotton pad for application to appropriate skin areas. Do not use full strength on face.
Warning: Avoid getting in eyes or mucous membranes. In case of serious wounds or burns consult a physician. If redness, irritation, swelling, pain or infections occur, stop use immediately and consult a physician. Keep out of reach of children and animals.
