Aromatherapy, botanicals, and essential oils in acne

Complementary and alternative medicine approaches are popular among some patient segments due to the perception that they are "natural" and thus are believed to be less likely to be dangerous, to be less toxic, or to cause fewer side effects. In dermatology, these can include aromatherapy, botanicals, and essential oils (plant extracts). Preliminary evidence, biological activity studies, and small pilot clinical trials conducted outside of North America, mostly in young adults, suggest that some may have value in acne treatment. When additional research and larger clinical trials are conducted, both clinicians and patients will be able to understand the risks and benefits compared with allopathic remedies.
