Research has not established a direct link between alcohol consumption and the development of acne. However, alcohol affects many parts of the body and may influence skin health.
Some of alcohol’s effects that may indirectly cause or worsen acne include:
Dehydration can cause a range of problems and may lead to acne breakouts. In addition, dehydration can make the skin look sunken or saggy.
Alcohol is a diuretic, meaning that it increases the production of urine, flushing out more salt and water than usual. As a result, consuming alcohol can lead to dehydration.
Drinking plenty of water is the best way to stay hydrated. If a person is drinking alcohol, they should consider having a glass of water between alcoholic drinks.
Reduced immune function
Experts believe that alcohol may lessen the function of the immune system — that even moderate amounts of alcohol may alter a person’s immune response.
A reduced immune response may, therefore, make a person more open to infection with Propionibacterium acnes (P. acnes) bacteria, which can contribute to acne breakouts or cause breakouts to become more inflamed.
Evidence increasingly indicates that inflammation occurs at all stages of acne.
P. acnes are bacteria that colonize the skin, and when they enter clogged pores, they can cause or worsen inflamed acne lesions, such as pustules.
Many things can cause inflammation, including chronic disease, hormone imbalances, and dietary factors. Alcohol, especially combined with sugary mixers, may contribute to inflammation and make acne worse.
Alcohol, meanwhile, can cause changes in hormone levels. For example, a study published in the American Journal of Clinical Nutrition found that for every alcoholic drink a healthy female consumed, her levels of estradiol, testosterone, and luteinizing hormone increased.
Buildup of toxins
Consuming alcohol can lead to alcoholic liver disease.
The liver is responsible for filtering toxins from the body, and frequent alcohol use can make it more difficult for the liver to remove all the toxins.
If the liver cannot effectively remove toxins, they may build up or leave the body through other pathways, such as the skin, reducing skin health.
While there is no direct link between alcohol and acne, various harmful health effects of alcohol may indirectly cause acne or make it worse.
Alcohol’s effects on the immune system, liver function, inflammation, and hormones may reduce skin health and contribute to acne.
Also, the AAD recommend avoiding skin care products that contain alcohol, which could irritate or dry out the skin.
