Evergreen monthly benchmark — Sep 4
Skincare
Sep 4Rank Trend
How top brands moved week over week. Rank 1 is the top position.
CeraVe appears in every single response that named a brand at all. It takes a top three position on all four engines and first place on three of them. La Roche-Posay is the consistent second and also reaches the top three everywhere. Below those two the engines diverge more sharply than in any category measured so far.
Top Brands by AI Mention Frequency
Mention frequency counts how many times a brand appeared across all AI responses. This differs from top-pick rank, which reflects each model’s #1 choice.
Opportunity for Brands
- Neutrogena is the clearest case of reach without authority here.
- It is named by all four engines and reaches the top three on none of them.
- The Ordinary has the opposite shape and is worth watching for it.
- It is named by only three engines but reaches the top three on two of those, including first place on Claude.
- Ten of the nineteen brands were named exactly once and every one of them appeared on a single engine.
- Which engine a challenger brand can reach matters more in skincare than in any category measured so far.

4 agents · top 3 each
| Agent | #1 | #2 | #3 |
|---|---|---|---|
| chatgpt | CeraVe | The Ordinary | La Roche-Posay |

| gemini | La Roche-Posay | CeraVe | Cetaphil |

What This Means
- The top of the table agrees and the middle does not.
- Three engines put CeraVe first and Gemini puts La Roche-Posay first, but all four rank both in the top three.
- Breadth is where they part company.
- Gemini named fourteen distinct brands and Claude named five.
- Gemini alone accounts for eight brands that no other engine mentions, including Cetaphil in its own top three.
- Perplexity answered the open question entirely in ingredients and named no brand in that response.
Why These Brands Win
- Simplicity is the reason given most often, and every engine argues for three or four products rather than ten.
- Ceramides and barrier support are the ingredient language used to justify the leaders.
- Daily broad spectrum sunscreen is named by all four engines as the single highest value step.
- Fragrance free formulation is treated as a requirement rather than a preference.
- Every engine also warned against introducing several active ingredients at once.

How we measure this
Each benchmark runs the same standardized prompts across multiple leading AI systems, including ChatGPT, Claude, Gemini, and Perplexity. We use consistent, category-specific questions designed to surface genuine product recommendations — not sponsored results.
Responses are parsed to extract brand mentions, rank position, and frequency. We then analyze cross-model agreement, identify which brands consistently appear in top positions, and flag where AI outputs diverge from marketplace trends.
Evergreen categories are benchmarked monthly. Results reflect organic AI behavior at the time of testing. Read the full methodology
