While research is limited, some studies suggest that caffeine may exacerbate psoriasis symptoms in certain individuals, but results can vary widely.
Psoriasis sufferers often wonder if their daily coffee habit worsens their skin condition. The relationship between caffeine and psoriasis is complex, with research showing both potential benefits and risks. Understanding this connection can help you make informed choices about your coffee consumption.
The Caffeine-Psoriasis Connection
Caffeine affects psoriasis in multiple ways. As an antioxidant, it may help reduce inflammation – a key factor in psoriasis flare-ups. However, caffeine can also stimulate stress responses that might trigger symptoms in some individuals.
How Caffeine Impacts Psoriasis
Caffeine influences psoriasis through several mechanisms:
- Modulates cAMP levels in skin cells
- Acts as both anti-inflammatory and pro-inflammatory agent
- Affects stress hormones that may trigger flares
What Research Says About Coffee and Psoriasis
A large study tracking 82,000 people found no link between coffee consumption and developing psoriasis. However, research on existing psoriasis shows more nuanced results.
| Cups Per Day | Effect on Psoriasis |
|---|---|
| 1-3 cups | May reduce flare severity |
| 4+ cups | Associated with worse symptoms |
The Goldilocks Zone for Coffee Drinkers
The 2018 study of 221 psoriasis patients revealed that moderate coffee drinkers (about 3 cups daily) had the mildest symptoms. Those consuming 4+ cups experienced more severe flares.
Individual Responses Vary
Many MyPsoriasisTeam members report coffee as a trigger, while others notice no effect. One member shared: “Caffeine makes my anxiety worse, which in turn makes my psoriasis worse, so I try to have less of it.”
Testing Your Personal Tolerance
Consider a 2-4 week caffeine elimination trial to assess your personal response. Gradually reduce intake to avoid withdrawal headaches.
Beyond Coffee: Other Dietary Considerations
While managing coffee intake, also consider other dietary factors that affect psoriasis:
- Nightshade vegetables (tomatoes, peppers)
- Processed foods and sugars
- Alcohol consumption

Topical Caffeine: A Potential Treatment
Interestingly, research shows caffeine applied directly to skin may help psoriasis. Scientists are developing caffeine-based topical treatments, though DIY versions aren’t well-studied.
How Topical Caffeine Works
When applied to skin, caffeine may:
- Reduce inflammation in psoriatic plaques
- Slow excessive skin cell growth
- Improve skin barrier function
Managing Caffeine Intake
If you choose to consume coffee with psoriasis, consider these tips:
Optimal Consumption Practices
- Limit to 2-3 cups daily
- Avoid drinking after 2pm to prevent sleep disruption
- Stay hydrated – caffeine is a diuretic

The Stress Connection
Caffeine’s impact on stress hormones may indirectly affect psoriasis. Many patients report stress as a major trigger for flares. If coffee increases your anxiety, it might worsen symptoms through this pathway.
Alternative Beverages
Consider these lower-caffeine options:
- Green tea (contains L-theanine for calm focus)
- Chicory root “coffee”
- Golden milk (turmeric-based drink)
According to a recent survey, about 30% of psoriasis patients report improvement after reducing caffeine, while others notice no change.
When to Consult Your Doctor
Discuss coffee consumption with your dermatologist if you experience:
- Noticeable flare-ups after caffeine
- Difficulty controlling psoriasis symptoms
- Concerns about medication interactions
