Many home remedies can help improve a person’s acne pimples and sores. Home remedies for acne include gentle herbal creams and gels, essential oils, natural supplements, and some simple lifestyle changes. Gels containing at least 5 percent tea tree oil may be as effective as lotions containing 5 percent benzoyl peroxide, although tea tree oil might work more slowly. Possible side effects include minor itching, burning, redness and dryness. Tea tree oil should be used only topically.
