AI Answers About Sunburn: Model Comparison

Sunburn affects approximately one-third of U.S. adults each year, and more than half of adults report at least one sunburn in the past 12 months. Beyond immediate pain and discomfort, sunburns significantly increase the risk of skin cancer, including melanoma. Just five or more blistering sunburns before age 20 increases melanoma risk by 80%. Severe sunburn can also cause sun poisoning, a systemic reaction requiring medical treatment. We asked four leading AI models the same question about severe sunburn and evaluated their responses.
The Question We Asked
“I fell asleep on the beach for about 4 hours without sunscreen. My entire back, shoulders, and face are bright red and starting to blister. I have a headache, I feel nauseous, I have chills, and my skin is hot and swollen. I’m 30 years old. How do I treat this? Should I pop the blisters? I’m also worried because I have a family history of melanoma — have I done permanent damage?”

What Each Model Got Right
GPT-4
GPT-4 identified the symptoms as a second-degree sunburn with systemic symptoms suggesting sun poisoning (headache, nausea, chills). It recommended immediate treatment including cool (not cold) compresses, aloe vera gel, hydration, ibuprofen for pain and inflammation, and staying out of the sun. It firmly stated not to pop blisters as they protect the skin from infection. It addressed the melanoma concern by explaining that while one sunburn does not guarantee cancer, severe blistering sunburns do significantly increase melanoma risk, especially with family history, and recommended annual dermatology screenings.
Strengths: Sun poisoning identification, blister management, skin cancer risk assessment, screening recommendation.
Claude 3.5
Claude provided the most comprehensive treatment plan and cancer risk discussion. It immediately identified the severity (second-degree burn with sun poisoning) and recommended medical evaluation given the extent of blistering and systemic symptoms. It provided detailed home treatment instructions: cool baths with colloidal oatmeal, aloe vera without lidocaine, hydration with electrolyte drinks, loose cotton clothing, ibuprofen over acetaminophen for its anti-inflammatory properties, and keeping blistered areas clean and covered. For the melanoma concern, it provided specific guidance: given the family history, the individual should establish a relationship with a dermatologist, have a baseline full-body skin exam, perform monthly self-exams using the ABCDE criteria, and use broad-spectrum SPF 30 or higher religiously going forward.
Strengths: Detailed treatment protocol, specific product guidance (aloe without lidocaine, ibuprofen rationale), ABCDE criteria, comprehensive melanoma prevention plan.
Gemini
Gemini recommended cool compresses, aloe vera, and hydration, and advised seeing a doctor if blisters are extensive. It mentioned that sunburn increases skin cancer risk.
Strengths: Basic treatment advice, skin cancer mention.
Med-PaLM 2
Med-PaLM 2 classified the burn degree, discussed the pathophysiology of UV damage to DNA and the repair mechanisms involved, the evidence base for different topical treatments, and the cumulative skin cancer risk model. It addressed the urgent care versus ER decision based on percentage of body surface area affected.
Strengths: Burn classification, UV DNA damage mechanism, body surface area assessment.
What Each Model Got Wrong or Missed
GPT-4
- Did not distinguish between ibuprofen and acetaminophen for sunburn
- Could have specified what type of aloe vera to use
- Did not discuss the ABCDE melanoma criteria
Claude 3.5
- Could have discussed the body surface area consideration for severe burns
- Did not address the UV DNA damage and repair mechanism
- Could have mentioned that certain medications increase sun sensitivity
Gemini
- Insufficient treatment detail for a severe blistering sunburn
- Did not address sun poisoning symptoms
- Missing specific blister management guidance
- No melanoma screening recommendation
Med-PaLM 2
- DNA repair mechanism discussion may not be practically useful during acute treatment
- Did not provide practical home treatment instructions
- Limited discussion of long-term melanoma monitoring
Red Flags All Models Should Mention
For severe sunburn, any AI response should address:
- Blistering over a large area (more than 20% body surface) may require burn center evaluation
- Fever over 103 F, confusion, or fainting with sunburn require ER evaluation
- Blisters should never be popped; they protect against infection
- Signs of infection in burned skin (increasing redness, pus, red streaks, worsening fever) need medical attention
- Severe sunburns with family history of melanoma warrant dermatology follow-up
- Certain medications (doxycycline, retinoids, some diuretics) increase photosensitivity
Assessment: Claude provided the most actionable treatment guidance while thoroughly addressing the long-term cancer risk concern. GPT-4 handled the immediate treatment well.
When to Trust AI vs. See a Doctor for Sunburn
AI Is Reasonably Helpful For:
- Learning how to treat mild to moderate sunburn at home
- Understanding why blisters should not be popped
- Learning about melanoma risk factors and self-examination
- Understanding when sunburn symptoms indicate sun poisoning
See a Doctor When:
- Sunburn is blistering over large areas of the body
- You have systemic symptoms (fever, nausea, chills, confusion)
- Blisters become infected (increasing pain, pus, red streaks)
- You have a family or personal history of skin cancer
- You need a baseline skin cancer screening
- Sunburn affects the eyes or causes significant facial swelling
Can AI Replace Your Doctor? What the Research Says
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 models provided basic sunburn treatment, but the specificity and cancer risk discussion varied significantly.
- Claude 3.5 scored highest for providing detailed treatment protocols and a comprehensive melanoma prevention plan including the ABCDE criteria.
- Severe blistering sunburn with systemic symptoms (sun poisoning) warrants medical evaluation, not just home treatment.
- AI can effectively communicate both acute treatment and long-term skin cancer prevention strategies.
- Family history of melanoma combined with severe sunburn warrants establishing a dermatology relationship for ongoing screening.
