There are many suggested home remedies for acne, but not all of them are supported by research.

Diet: It is unclear what role diet plays in worsening acne. Scientists have found that people who consume a diet that offers a good supply of vitamins A and E and of zinc may have a lower risk of severe acne.

Tea-tree oil: Results of a study of 60 patients published in the Indian Journal of Dermatology, Venereology, and Leprology suggested that 5-percent tea-tree oil may help treat mild to moderate acne.

Tea: There is some evidence that polyphenols from tea, including green tea, applied in a topical preparation, may be beneficial in reducing sebum production and treating acne. However, the compounds, in this case, were extracted from tea, rather than using tea directly.

Moisturizers: These can soothe the skin, especially in people who are using acne treatment such as isotretinoin, say researchers. Moisturizers containing aloe vera at a concentration of at least 10 percent or witch hazel can have a soothing and possibly anti-inflammatory effect.
