Rosacea Triggers: Alcohol, Spicy Food and Heat, What Studies Show

If your cheeks flush with a glass of wine, a hot shower or a summer afternoon, you’ve met rosacea triggers. Triggers differ from person to person, which is why dermatologists often ask patients to find theirs before treatment starts.¹

What patients report

A survey of 1,066 people with rosacea asked what set off their flares:²

Trigger	Share affected
Sun exposure	81%2
Emotional stress	79%2
Hot weather	75%2
Wind	57%2
Heavy exercise	56%2
Alcohol	52%2
Hot baths	51%2
Spicy foods	45%2
Skin-care products	41%2
Hot drinks	36%2
Dairy	8%2

This was a self-report survey run by a patient organization, so it shows what people notice, not what’s proven.

Why food and drink might matter

A 2017 review grouped diet triggers into four families: heat (hot drinks), alcohol, capsaicin (hot peppers) and cinnamaldehyde (found in cinnamon).³ It proposed they may act on sensors in the skin that widen blood vessels, and said more research is needed.³

Does alcohol cause rosacea?

That’s a different question from whether a drink makes you flush tonight. A study followed 82,737 US nurses for 14 years:⁴

• Women who drank 1 to 4 grams of alcohol a day, well under one drink, had about 12% higher risk of a rosacea diagnosis than never drinkers.⁴
• Those drinking 30 grams or more, roughly two drinks, had about 53% higher risk.⁴
• White wine and liquor showed the link.⁴

It was observational and didn’t look at causes.⁴

Find your own triggers

1. Keep a diary for at least two weeks: foods, drinks, products, sun, heat and cold, and how your face felt.¹
2. Note warmth, not just redness. If your cheeks feel warm, you may be flushing, even if the color change is hard to see.¹
3. Change one thing at a time for a couple of weeks and compare.
4. Wear daily sunscreen, since sun is the most common trigger reported.²

For the basics and treatment, see why is my face always red? and rosacea treatments compared.

Try: “My face flushes with wine, hot showers and spicy food, and the redness is lasting longer. I’ve kept a two-week diary. Could this be rosacea, and what treatment fits my pattern?”

Skin, Head to Toe covers this in Chapter 10, “Red in the Face, and Other Clues,” in a section called “Triggers and What Helps.” Its Skin Log adds one line each evening for anything hot, spicy or alcoholic, sun or heat, and how your cheeks felt, so repeats show up before you cut anything out.
