Acne is a skin condition that manifests itself as red swellings and bumps called pimples. The Mayo Clinic explains it is commonly treated with chemicals such as benzoyl peroxide, sulfur, lactic acid, resorcinol or salicylic acid. However, there are also some natural remedies that may reduce or eliminate acne without applying harsh products. According to the Mayo Clinic, studies have shown that brewer's yeast may be an effective acne treatment. It may not work for everyone, but it can help some acne sufferers who prefer to try natural options first.
Acne results from three main factors, the Mayo Clinic states. Dead skin cells are not shed properly, which irritates the hair follicles. This combines with secretion of too much oil and an overabundance of bacteria to cause pimples. Acne usually crops up on the face and other areas with a lot of oil glands, like the neck and shoulders.
Teenagers are most prone to acne because of the hormonal changes that take place during adolescence, but adults can get it too. Women are especially prone due to hormone fluxes caused by the menstrual cycle or pregnancy. Yeast can be used as a treatment by anyone who suffers from acne, regardless of age or sex.
Brewer's yeast treats acne by killing excess bacteria, as well as by supporting production of white blood cells, the acnetalks.com educational site explains. These extra white blood cells can fight infection in the hair follicles. Brewer's yeast also is also rich in nutrients such as riboflavin, vitamin B12, pantothenic acid and biotin, which may also be beneficial. It will fight current acne outbreaks and prevent acne from developing in the future.
Health911.com recommends using brewer's yeast to fight acne by taking two teaspoons every day. Alternately, one brewer's yeast tablet can be taken following every meal. This treatment should be accompanied by keeping the skin clean to complement the yeast's benefits by cutting down as much as possible on oil and bacteria growth.
Acnetalks.com warns that brewers yeast can have unpleasant and potentially dangerous side effects in some people. Minor effects include headaches, bloating and excess gas. People with allergies can break out in a rash and their skin can swell and feel itchy. Severe allergies may cause breathing problems and may require medical attention.
