Alcohol and acne: drinking, antibiotics, skin

Alcohol and acne come up in two different ways. People ask whether drinking causes breakouts, and they ask whether rubbing alcohol on a spot will dry it out. The evidence for the first is a handful of surveys and one laboratory study. The advice for the second is clearer. This guide covers both, plus how alcohol fits with the antibiotics used for acne. It is part of Skinli's acne diet guide. If you take isotretinoin, read Accutane and alcohol instead, because that medicine has its own rules.

What studies of drinking show

No trial has asked people with acne to stop drinking and then counted their spots. The evidence comes from surveys that compare drinkers with non-drinkers.

Study	Who	Finding
Malaysia, BMC Public Health, 2021	1,840 Malaysian Chinese adults	Drinkers had 29 percent higher odds of having acne than non-drinkers
Singapore, Dermatology, 2022	3,888 Singapore Chinese adults	Drinking was linked to more severe acne
Germany, Nutrients, 2023	120 people with acne and 32 without	Limiting alcohol appeared helpful for acne and rosacea

How the surveys worked

The Malaysian study compared 1,117 people with acne and 723 without. A researcher asked each person the questions, and trained staff graded acne severity and scarring. After the researchers accounted for age and sex, drinkers still had 26 percent higher odds of having acne. The Singapore study, by the same research group, compared 2,090 people with acne and 1,798 without, with a median age of 21. Its summary reports a link between drinking and more severe acne, and names other factors, such as screen time, for having acne at all.

The German study took a different approach. It asked people with acne and people with rosacea to rate which foods and drinks helped or harmed their skin, then measured their diets with a standard food questionnaire. Of the people with acne, 80.8 percent said diet affected how severe their acne was.

What the results mean

The Malaysian study also found that drinkers had higher grades of acne scarring. That link disappeared once the researchers accounted for age and sex. In the German study, people with acne named alcohol among the foods and drinks they thought made their skin worse, after chocolate, fried foods, refined sugar and milk.

These results need care. The two Asian studies included only Chinese adults, so their results describe that group. The Malaysian authors write that in their own earlier review, alcohol intake was mostly not linked to acne, and that most previous studies found no link. So the recent findings go against much of the older research. All three studies measured drinking and acne at the same time, so none can show whether drinking came first. People who drink may also differ from non-drinkers in other ways, and a survey cannot fully separate those differences.

What the laboratory study found

A 2024 study in the journal Cells looked for a reason alcohol might affect acne. Researchers grew human oil gland cells in a dish and added ethanol, the alcohol in drinks. The more ethanol they added, the more fat the cells made. At 1 percent ethanol, the lowest amount in that test, fat production rose to 147 percent of normal after 24 hours. At 4 percent, it rose to 1,532 percent of normal.

The researchers also found that the effect came from substances the cells made while breaking down ethanol. They concluded that their results give an explanation for acne in heavy drinkers.

The limits matter here. The study used cells in a dish and included no people. It did not measure how much alcohol reaches the skin after a drink, and it did not study anyone's acne. It gives a possible reason for the survey findings, and it cannot show that moderate drinking causes acne.

The researchers checked their result in two kinds of cells: a standard laboratory line of human oil gland cells, and oil gland cells grown from stem cells. Both made more fat when ethanol was added. Methanol, a different alcohol, had no effect on fat production. Ethanol also reduced how much energy the cells' mitochondria, the parts that produce energy, could make.

Rubbing alcohol on spots

Putting alcohol on acne is a separate question, and the advice from dermatologists is direct.

The American Academy of Dermatology (AAD) advises using gentle skincare products labeled "alcohol-free". It also advises avoiding products that can irritate the skin, including astringents, toners and exfoliants, because they can dry the skin and make acne look worse. Its guide to face washing recommends a gentle cleanser that does not contain alcohol.

The 2024 laboratory study adds a further reason. Propanol, an alcohol found in many rubbing alcohols, hand sanitizers and cosmetics, made oil gland cells produce 1,298 percent of their normal fat at the lowest amount tested. At higher amounts it damaged the cells. The authors conclude that putting propanol on acne, as some internet forums suggest, does not seem helpful.

For a single spot, use an ingredient with evidence behind it. The NHS lists benzoyl peroxide and salicylic acid as acne treatments you can buy from a pharmacy. See the acne spot treatment guide for how to use them.

Alcohol and acne medicine

Some acne medicines have advice about alcohol, and it differs between them. Doxycycline is one of the antibiotic tablets the 2024 AAD acne guideline recommends, so this matters for many people with acne:

• Doxycycline. The NHS says it is best not to drink alcohol while taking it, because alcohol can stop the medicine working properly.
• Lymecycline. The NHS says you can drink alcohol while taking it.
• Isotretinoin (Accutane). This medicine has its own advice, covered in Accutane and alcohol.

Ask your pharmacist about any medicine you take, including creams and gels. Tell them how much you drink, so they can give advice that fits your dose and your drinking.

Alcohol, flushing and rosacea

If your face turns red and flushed after a drink, the cause may be rosacea. The NHS lists alcohol, spicy foods and hot drinks among common rosacea triggers, and advises avoiding a trigger as much as possible once you know it makes symptoms worse. Other early signs the NHS lists are redness that comes and goes across the nose, cheeks and forehead, and burning or stinging when using water or skincare products. It adds that the redness may be harder to see on brown or black skin. Rosacea can cause spots that look like acne, and it needs different treatment. Rosacea vs acne explains how to tell them apart, and a doctor can confirm which one you have.

Late nights and sleep

Drinking often goes with late nights, and sleep has its own link to acne in surveys. A 2024 Saudi study of 1,983 adults found a link between shorter sleep and acne. A 2024 Indian study of 140 adults found that sleeping less than six hours a night was linked to acne that started after age 25. Both studies measured sleep and acne at the same time, so they cannot show that short sleep causes acne. If your breakouts follow nights out, sleep is one more thing that changed.

Sugary drinks and mixers

Many alcoholic drinks come with sugar. The AAD lists sugary drinks among high glycemic foods, which raise blood sugar fast, and small trials link a diet low in these foods to less acne. A 2020 French study of 24,452 adults linked current acne to sugary drinks. If you drink cocktails or sweet mixers, the sugar may matter as much as the alcohol. High glycemic foods and acne covers the evidence.

What to do

1. Look at the pattern. Do breakouts follow weekends when you drink more? Take photos to check. The progress tracker keeps them in order.
2. Test a change. Cut back for a month and keep your skincare the same. The AAD suggests testing any food or drink this way.
3. Keep alcohol off your spots. Use an alcohol-free routine and a spot treatment with evidence behind it. Look for the words "alcohol-free" on the label, the wording the AAD suggests.
4. Keep treating the acne. The AAD says clear skin needs acne-friendly skincare and acne medicine. Analyze your skin builds a free routine from a photo.

NICE, which writes health guidance for England, says there is not enough evidence to support specific diets for treating acne. If cutting back on alcohol feels hard, a doctor can help with that too.
