### Alternative Treatments for Acne and Expert Opinions People with acne often turn to complementary or alternative treatments. These may include gels, creams, and lotions; dietary supplements and herbs; and special dietary routines. Many people swear by alternative acne treatments. But the American Academy of Dermatology (AAD) says that "all-natural supplements" have not been shown to be effective, and some may even be harmful. For example, the group cites an over-the-counter (OTC) acne supplement that contained more than 200 times the amount of selenium stated on the label. It caused a wide range of toxic reactions. The AAD also states that there is emerging research that suggests that high glycemic index diets (those high in processed carbs and sugar) and dairy (particularly skim milk) may be associated with acne. Alternative acne treatments haven't been well-studied. Therefore, sources such as the Natural Medicines Comprehensive Database typically offer only tepid recommendations. For instance, oral zinc supplements are rated as only "possibly effective." The same is true for topical preparations that contain zinc. Until there is better research, it's impossible to say which alternative acne treatments work and which ones don't. Conventional acne treatments don't always work for everyone. They can also cause side effects ranging from skin irritation to birth defects. Another concern, since antibiotics are used in so many conventional acne treatments, is antibiotic resistance. A study in the U.K. reported that more than one out of every two acne patients treated with antibiotics carried resistant strains of two different bacteria often found on the skin. Proponents of alternative treatments point out that acne is unknown in so-called "Stone Age" societies. On the other hand, it affects up to 95% of adolescents in industrialized societies. This suggests, they say, that a Western diet may be a major factor in the development of acne. Hundreds of alternative treatments for acne are promoted on the Internet and elsewhere as being safe and effective. Alternative treatments, though, do not need to be tested and shown to be safe before they are sold online or placed on store shelves in the U.S. So, be sure to discuss the pros and cons of any alternative remedy with your doctor or dermatologist before starting treatment. Research is not conclusive, but some preliminary studies suggest that the following alternative acne treatments might offer some benefits. **Manuka Honey**: Manuka honey comes from New Zealand where the manuka bush is indigenous. So-called "active" manuka honey is widely promoted on the Internet as an acne remedy. The claim is mostly based on studies that suggest it has significant antibacterial and wound-healing properties. However, there have been no definitive studies to prove or disprove the effectiveness of manuka honey. **Tea Tree Oil**: Tea tree oil is an essential oil extracted from the leaves of a small tree native to Australia. It has long been touted as a safe and effective alternative treatment for acne. In a widely-cited study, tea tree oil was found to result in a similar reduction in acne lesions as benzoyl peroxide after three months, with fewer side effects. However, tea tree oil should never be taken orally as it can cause toxic reactions. **Tannins and Fruit Acids**: Some practitioners recommend topical treatments containing tannins or fruit acids. Tannins have natural astringent properties, while fruit acids like citric, glycolic, and malic acids help remove skin. These treatments have not been extensively studied. Always consult your doctor or dermatologist before starting any new treatment for acne.
