Do you think i should apply tea tree oil all over my face or just on acne scars?

Myth but use if help: Many of my patients swear by the benefits of tea tree or bio-oil and so i generally don't dissuade them but there is very little science to support its use. It is probably the massage, (which we know helps scars) that is used to apply the oil, which is actually providing the improvements observed. Massage with any clean oil 3-4 times a day. Silicon gel trips are morel likely to improve the scar.
