## Headline findings

### 1. The recommendation is almost perfectly stable — and it is three brands

**CeraVe Moisturizing Cream was the top pick in 5 of 5 runs.** No churn at all at the top.

Across all five runs the *entire* recommended brand set is **CeraVe, Vanicream, La Roche-Posay**.
Three brands. That is the whole shelf a person asking this question is offered.

### 2. Those three brands are Google's #1, #2 and #4

Google organic shelf: CeraVe (1), La Roche-Posay (2), The Ordinary (3), Vanicream (4).

| Depth | Brand overlap |
|---|---|
| Top 10 | **3/3 = 100%** |
| Top 40 | **3/3 = 100%** |

Unlike q02, **there is no decay here** — because ChatGPT named so few brands, and all of them
sit in Google's top four. This is the strongest single-query result in the study so far.

### 3. SKU-level is looser than brand-level (again)

Exact Google top-40 matches: CeraVe Moisturizing Cream (G#1), LRP Toleriane Double Repair
(G#2), Vanicream Daily Facial Moisturizer (G#4).
Non-matches: **Vanicream Moisturizing Cream** (Google has the *Daily Facial* SKU, not this one),
**LRP Lipikar AP+Max Triple Repair** (Google has *Lipikar Balm AP+*), **CeraVe Intensive**
(absent from Google top 40).

Brand 100%, SKU roughly half. Consistent with q02.

### 4. Run 4 cites the sellers as evidence for the sellers

Run 4's "Why I'd pick it" bullets are sourced to **CeraVe's own site** and
**La Roche-Posay's own site**, alongside Cleveland Clinic and Nebraska Medicine.

Brand-owned marketing copy is being cited as support for recommending that brand. Not
presented deceptively — the chips are visible — but it completes the picture: the "evidence"
layer under a purchase recommendation includes the seller.

Combined with the Nebraska Medicine finding (a hospital SEO page that endorses an *ingredient
class*, never CeraVe), the authority stack under this recommendation is: hospital content
marketing, a professional body's general guidance, a news outlet, and the manufacturers.

### 5. Three separate commercial layers are now visible in one answer

1. **Product cards** — CeraVe, Vanicream, LRP with retailer and price.
2. **Nordstrom Rack carousel** — 3 of 5 runs, always the same four First Aid Beauty products
   ($28/$42/$38/$27). A merchant placement, not a recommendation. FAB *is* in Google's organic
   top 40 (#23, at $20.00) but at different SKUs and prices.
3. **Ad units** — 2 of 5 runs. Protocol Lab (a vitamin C serum, off-category) and Tallow Me
   Pretty (a face cream, on-category).

### 6. Price ambiguity, stated carefully

CeraVe Moisturizing Cream: **$15.97·Walmart in 4 runs, $17.99·Ulta Beauty in 1.** Google's
organic shelf listed the same product name at **$4.19** (Target, $2.22/oz → roughly a 1.9oz
size).

Almost certainly a **size difference, not a wrong price** — CeraVe Moisturizing Cream ships in
several sizes. But neither surface shows the size prominently, so a shopper comparing the two
sees the same product name at a ~4x spread with nothing explaining it. **Frame as ambiguity.
Do not call it a hallucination.**
