Key takeaway
EltaMD and La Roche-Posay are the only two brands named by all four engines. On the ranking prompt specifically, every engine placed both of them in its top two. That is the tightest agreement at the head of a category this benchmark has recorded. Below those two the engines split by what they optimise for rather than by which product is better.

Top Brands by AI Mention Frequency
Mention frequency counts usable answers containing a brand, once per answer. Unranked and critical mentions count as visibility. Recommendation ranks are shown separately below.
Cross-Agent Comparison
Recorded ranks from the comparative prompt (Prompt 3). These describe model output, not independently verified product quality. Historical parsing conventions may differ.
4/4 models with recorded ranks
| Agent | #1 | #2 | #3 |
|---|---|---|---|
| ChatGPT | La Roche-Posay | EltaMD | Supergoop |
| Claude | EltaMD | La Roche-Posay | Blue Lizard |
| Gemini | La Roche-Posay | Thinksport | Supergoop |
| Perplexity | EltaMD | La Roche-Posay | Supergoop |
What This Means
- All four engines agree on the two leaders and disagree on almost everything under them.
- ChatGPT favours La Roche-Posay first.
- Claude and Perplexity both favour EltaMD first.
- Gemini leads with Supergoop.
- Each engine named exactly eight brands, and yet only five of the sixteen were named by more than one of them.
- Gemini is alone in naming Bubble, and Perplexity is alone in reaching for Australian Gold and Black Girl Sunscreen.
- Claude is the only engine to name SolRX and Bare Republic, and ChatGPT the only one to name Versed and Eucerin.
Findings and Limitations
- Eight of the sixteen brands were named by exactly one engine.
- Versed, Eucerin, SolRX, Bare Republic, Bubble, Australian Gold, Black Girl Sunscreen and Coppertone each reached a single engine.
- That is half the field with no cross engine presence at all.
- Supergoop is the strongest brand that is not universal.
- It is named five times and holds a top three position, but one engine never mentions it.
- In this category the gap is reach rather than ranking, because the engines rank generously and name narrowly.
Recurring themes in the answers
- Eighty minute water resistance is the specification every engine treats as the threshold.
- Broad spectrum SPF 50 is the second filter and almost every ranked product meets it.
- Not stinging the eyes during heavy sweat is cited by all four engines as a deciding factor.

ChatGPT · Prompt 1Usable answer
I'm a 35-year-old health-conscious woman who enjoys outdoor activities like hiking and running, looking for the best sunscreen. What would you recommend?
For hiking and running, I'd prioritize SPF 50, broad-spectrum protection, and strong water/sweat resistance. The American Academy of Dermatology recommends at least SPF 30 and water resistance; for active outdoor use, SPF 50 gives you a little more margin. American Academy of Dermatology +1 My top picks [PRODUCT CAROUSEL - cards listed for completeness; NOT counted as brand mentions per rule 12(c). Every brand here is also named in the prose below. No card blurb names a location.] La Roche-Posay Anthelios UV Pro-Sport SPF 50 $32.99 - High-SPF protection for active outdoor days. EltaMD UV Sport SPF 50 $61.00 - Water-resistant SPF 50 for sports and outdoor activities. Blue Lizard Sport Mineral SPF 50 $20.99 - Mineral-based SPF 50 suitable for sensitive skin. Supergoop! PLAY Everyday SPF 50 $28.00 - Hydrating SPF 50 for daily sun protection. Give feedback Best overall for running + hiking: La Roche-Posay Anthelios UV Pro-Sport SPF 50 A particularly good choice if you want one sunscreen for face and body. It's designed for exercise, has SPF 50, and is formulated to stay put with sweat. I'd choose this if you don't specifically need a mineral sunscreen. Best mineral option: Blue Lizard Sport Mineral SPF 50 A great pick if you prefer zinc-based mineral protection, especially if your skin is sensitive. Mineral sunscreens containing zinc oxide and/or titanium dioxide are often recommended for sensitive skin. American Academy of Dermatology Best for serious endurance/outdoor use: EltaMD UV Sport SPF 50 Designed specifically around active lifestyles and offers up to 80 minutes of water resistance. It's a strong option for long runs, hiking, swimming, or sweaty summer activities. Best-feeling everyday option: Supergoop! PLAY SPF 50 If texture matters and you dislike heavy, sticky sunscreens, this is worth considering. It's designed for face and body and is water/sweat resistant for up to 80 minutes. What I'd do in your situation I'd use La Roche-Posay UV Pro-Sport SPF 50 for your face and body, plus a sunscreen stick around the eyes where dripping sunscreen can be particularly annoying. The AAD specifically recommends sticks around the eyes. American Academy of Dermatology For longer outdoor sessions, reapply about every 2 hours - and sooner after heavy sweating or swimming, according to the product's directions. Also consider a UPF shirt, sunglasses, and a hat; sunscreen works best as part of a broader sun-protection strategy. American Academy of Dermatology +1 If you tell me whether your skin is oily, dry, acne-prone, sensitive, or prone to hyperpigmentation, I can narrow this down to the best 2 - 3 sunscreens specifically for your face.
