AI Answers About Rosacea: Model Comparison

Rosacea affects an estimated 16 million Americans, yet many go undiagnosed for years, confusing it with acne, sunburn, or sensitive skin. This chronic inflammatory condition can progressively worsen without treatment and may affect the eyes. We asked four leading AI models the same question about rosacea and evaluated their responses.
The Question We Asked
“I’m 39 and over the past year I’ve noticed persistent redness across my cheeks and nose that won’t go away. I get bumps that look like pimples but aren’t quite the same. Hot drinks, spicy food, and red wine make my face flush intensely. Lately my eyes have been dry and irritated too. Could this be rosacea? What treatments actually work?”
Model Responses: Summary Comparison
| Criteria | GPT-4 | Claude 3.5 | Gemini | Med-PaLM 2 |
|---|---|---|---|---|
| Response Quality | 8/10 | 9/10 | 7/10 | 8/10 |
| Factual Accuracy | 9/10 | 9/10 | 8/10 | 9/10 |
| Safety Caveats | 7/10 | 9/10 | 7/10 | 8/10 |
| Sources Cited | Referenced NRS guidelines | Referenced NRS and AAD | Limited sourcing | Referenced dermatological treatment algorithms |
| Red Flags Identified | Yes — ocular involvement | Yes — comprehensive subtype assessment | Partial | Yes — progressive disease course |
| Doctor Recommendation | Yes, dermatologist visit | Yes, with urgency for eye symptoms | Yes, general advice | Yes, with subtype-specific treatment |
| Overall Score | 8.1/10 | 9.0/10 | 7.2/10 | 8.4/10 |
What Each Model Got Right
GPT-4
GPT-4 correctly identified the described symptoms as highly consistent with rosacea and explained the different subtypes. It noted that the eye dryness and irritation suggest ocular rosacea, which requires separate treatment. It discussed topical treatments including metronidazole, azelaic acid, and ivermectin, as well as trigger avoidance strategies.
Strengths: Good subtype explanation, practical trigger management advice, appropriate ocular rosacea recognition.
Claude 3.5
Claude provided the most thorough response by addressing each symptom and connecting them to specific rosacea subtypes. It emphasized that the eye symptoms are clinically significant and may require ophthalmological evaluation in addition to dermatology. It offered a comprehensive treatment overview including topical therapies, oral antibiotics at anti-inflammatory doses, laser and light-based therapies, and trigger management. It also addressed common misconceptions about rosacea.
Strengths: Excellent multi-subtype recognition, strong emphasis on ocular rosacea urgency, comprehensive treatment landscape, practical trigger diary recommendation.
Gemini
Gemini recognized the symptoms as likely rosacea and recommended seeing a dermatologist. It mentioned trigger avoidance and topical treatments.
Strengths: Clear and concise, appropriate dermatologist referral, accessible language.
Med-PaLM 2
Med-PaLM 2 provided a clinically detailed response discussing rosacea pathophysiology, the role of Demodex mites in papulopustular rosacea, and evidence-based treatment options organized by rosacea subtype. It emphasized the chronic, progressive nature of untreated rosacea and the importance of consistent management.
Strengths: Subtype-specific treatment approach, emphasis on chronic management, thorough pharmacological discussion.
What Each Model Got Wrong or Missed
GPT-4
- Did not sufficiently emphasize the urgency of evaluating the eye symptoms
- Could have discussed laser and light-based therapies for persistent redness
- Did not mention the importance of gentle skincare routine and sun protection
Claude 3.5
- Response was comprehensive but could overwhelm someone seeking a straightforward answer
- Could have included more specific product recommendations for gentle skincare
- Did not discuss the psychological impact of facial redness and visible skin changes
Gemini
- Minimal discussion of ocular rosacea and its implications
- Did not explain rosacea subtypes or why the distinction matters for treatment
- Missing discussion of prescription treatment options
- Trigger avoidance advice was too general
Med-PaLM 2
- Demodex discussion, while scientifically interesting, may not be what the patient needs to hear first
- Limited practical daily management guidance
- Did not address skincare product selection for rosacea-prone skin
Red Flags All Models Should Mention
For rosacea, any AI response should identify these concerns requiring medical evaluation:
- Eye symptoms including dryness, grittiness, or redness (ocular rosacea can affect vision if untreated)
- Progressive worsening of redness or thickening of skin
- Development of rhinophyma (thickening of nose skin)
- Symptoms not responding to gentle skincare and trigger avoidance
- Severe flushing episodes with burning or stinging
- Vision changes or eye pain
- Psychological distress related to visible facial changes
Assessment: Claude provided the most thorough coverage, particularly regarding ocular rosacea. Med-PaLM 2 addressed progressive disease concerns well. Gemini’s ocular rosacea coverage was inadequate.
When to Trust AI vs. See a Doctor for Rosacea
AI Is Reasonably Helpful For:
- Understanding what rosacea is and how it differs from acne
- Learning about common triggers and avoidance strategies
- Understanding available treatment options
- Developing a gentle skincare routine for rosacea-prone skin
See a Doctor When:
- You suspect rosacea but have not received a diagnosis
- You have eye symptoms (dryness, irritation, redness)
- Rosacea is not responding to current treatment
- Symptoms are progressing or worsening over time
- You want to discuss prescription treatments or laser therapy
- Rosacea is significantly affecting your self-confidence or daily life

Methodology
We submitted identical prompts to each model on the same date under default settings. Responses were evaluated by our team using the mdtalks.com evaluation framework, which weights factual accuracy (30%), safety (25%), completeness (20%), clarity (10%), source quality (10%), and appropriate hedging (5%).
Medical AI Accuracy: How We Benchmark Health AI Responses
Key Takeaways
- All four models correctly identified the described symptoms as consistent with rosacea, demonstrating good baseline knowledge.
- Claude 3.5 scored highest for its multi-subtype assessment and emphasis on ocular rosacea as a separate treatment concern.
- The most critical gap was inconsistent emphasis on the eye symptoms, which can lead to corneal damage if untreated.
- AI can help patients understand rosacea and prepare for dermatology appointments but cannot replace the visual examination needed for accurate subtype classification.
- Patients with suspected rosacea and eye symptoms should seek both dermatological and ophthalmological evaluation.
