Can Coffee Cause Acne? What Science Says

If you're dealing with breakouts and wondering whether your daily coffee habit might be to blame, you're not alone. Many people worry that their morning cup could be making their acne worse. The good news: research shows that coffee itself doesn't directly cause acne. However, how you drink it and how much you consume might affect your skin.

What Research Says About Coffee and Acne

There's no direct scientific evidence linking coffee consumption to acne development. Studies examining coffee and skin health have actually found some benefits, including reduced risk of certain skin conditions. The confusion comes from how coffee might indirectly affect factors that contribute to breakouts.

How Coffee Might Affect Your Skin

The Stress Hormone Connection

Caffeine stimulates your body to produce cortisol, a stress hormone. When cortisol levels rise, your skin may produce more oil, which can contribute to clogged pores. One study found that stressed individuals who consumed caffeine experienced a 211% increase in cortisol levels. This effect is more noticeable if you're already prone to stress-related breakouts.

Sleep Quality Matters

Drinking coffee late in the day can disrupt your sleep. Poor sleep increases stress levels, which can worsen acne. If you notice more breakouts when you're tired, your coffee timing might be worth examining.

What You Add to Coffee Matters More

The Dairy Problem

Multiple studies show a clear link between dairy consumption and acne. A large analysis including over 78,000 participants found that any milk intake increased acne odds by 25%, with skim milk showing the strongest association at 32% increased risk. If you add milk or cream to your coffee, this could be the real culprit behind your breakouts.

Sugar's Impact on Skin

Added sugar in coffee can spike insulin levels, which triggers the release of a hormone called IGF-1. This hormone increases oil production and inflammation in your skin. Research consistently shows that high-sugar diets worsen acne by promoting these hormonal changes.

Practical Tips for Coffee Lovers

If you enjoy coffee and want to protect your skin:

• Drink black coffee or use dairy-free alternatives like almond or oat milk
• Skip the sugar or use minimal amounts
• Limit coffee to morning hours to avoid sleep disruption
• Keep consumption to 1-2 cups daily if you notice stress-related breakouts
• Stay hydrated with water throughout the day

When to See a Dermatologist

If you've adjusted your coffee habits and still struggle with acne, it's time to consult a dermatologist. They can identify underlying causes and recommend treatments tailored to your skin. Persistent or severe acne may require medical intervention beyond dietary changes.

The Bottom Line

Coffee itself doesn't cause acne, but what you add to it might. Dairy and sugar are the main concerns, with strong research linking both to breakouts. If you're experiencing acne, try switching to black coffee or dairy-free options before giving up your morning ritual entirely. Pay attention to how your skin responds, and don't hesitate to seek professional advice if breakouts persist.
