Complementary therapies have been investigated for treating people with acne. Low-quality evidence suggests topical application of tea tree oil or bee venom may reduce the total number of skin lesions in those with acne. Tea tree oil is thought to be approximately as effective as benzoyl peroxide or salicylic acid, but has been associated with allergic contact dermatitis. Proposed mechanisms for tea tree oil's anti-acne effects include antibacterial action against C. acnes, and anti-inflammatory properties. Numerous other plant-derived therapies have been observed to have positive effects against acne (e.g., basil oil and oligosaccharides from seaweed); however, few studies have been performed, and most have been of lower methodological quality. There is a lack of high-quality evidence for the use of acupuncture, herbal medicine, or cupping therapy for acne.
Shower twice a day. Take a shower or bath in the morning and at night. Alternatively, take a shower in the morning and then again after physical activity, like exercise, or sweating. Wash your entire body with a mild cleanser and use shampoos that limit oil production in your hair. Be sure to always shower after exercising to remove the dead skin cells your body has sloughed off through sweating.
Acne appears to be strongly inherited with 81% of the variation in the population explained by genetics. Studies performed in affected twins and first-degree relatives further demonstrate the strongly inherited nature of acne. Acne susceptibility is likely due to the influence of multiple genes, as the disease does not follow a classic (Mendelian) inheritance pattern. Several gene candidates have been proposed including certain variations in tumor necrosis factor-alpha (TNF-alpha), IL-1 alpha, and CYP1A1 genes, among others. The 308 G/A single nucleotide polymorphism variation in the gene for TNF is associated with an increased risk for acne. Acne can be a feature of rare genetic disorders such as Apert's syndrome. Severe acne may be associated with XYY syndrome.
Diet. Studies indicate that certain dietary factors, including skim milk and carbohydrate-rich foods — such as bread, bagels and chips — may worsen acne. Chocolate has long been suspected of making acne worse. A small study of 14 men with acne showed that eating chocolate was related to a worsening of symptoms. Further study is needed to examine why this happens and whether people with acne would benefit from following specific dietary restrictions.
