For a late-20s skincare buyer, AI routes to CeraVe and La Roche-Posay as the twin pillars in every engine, with Vanicream for sensitive skin, EltaMD for sunscreen, The Ordinary for cheap actives, and Paulas Choice for treatments. That six-brand core is unusually consistent for a category this fragmented. Below it, a brand is effectively invisible unless it owns a narrow slot in a specific engine, and heavy prestige marketing spend (Drunk Elephant, Tatcha, Glossier) buys almost no AI visibility.
Brands ordered by mention count in each run. Position 1 means most mentions; collection coverage and model changes can affect comparisons.

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.

What This Means
All four engines return the exact same three brands in their top 3 - CeraVe, La Roche-Posay, and Vanicream - merely permuted, which is the tightest three-brand consensus in the dataset.
The aggregate #1 splits two-to-two: La Roche-Posay leads for ChatGPT and Gemini, CeraVe leads for Claude and Perplexity, and whichever is not first is second or third in every case.
Below that identical core the engines diverge sharply in formatting and long tail.
ChatGPT is commerce-formatted with price-tagged SKU lists and uniquely surfaces Eucerin, Murad, Biore, and Kiehls.
Claude is the most structured and price-range-annotated, giving the deepest ten-brand ranking with explicit weaknesses per brand, and uniquely surfaces DHC.
Gemini is the most tier-based and trend-aware, organizing brands into clinical, actives, sun-protection, and medical-grade tiers, and uniquely surfaces SkinMedica, Clinique, The Inkey List, and elf.
Perplexity is the most citation-driven and consolidated, uniquely surfacing Drunk Elephant, Tatcha, and Blue Lizard.
The prestige tier is where the engines diverge most: three of four exclude prestige brands from the top ranks entirely.
Findings and Limitations
Skincare is the most contestable category tracked - the single-engine long tail is larger than any other category, meaning many real brands surface in exactly one engine and none has consolidated cross-model presence.
K-beauty is nearly absent this run (only Biore, via ChatGPT).
Indie and DTC actives brands (Naturium, Timeless, The Inkey List, Maelove, Dieux) cluster in one or two engines with no cross-model agreement.
Notably absent given retail and marketing spend: Olay, Garnier, Ponds, Glossier, Youth To The People, Krave, Good Molecules, and most prestige department-store brands.
Drunk Elephant and Tatcha appear only in Perplexity and only as caveated lower-value picks.
The dermatologist-recommended core remains entirely drugstore and medical-grade, and prestige marketing does not translate into AI recommendation.
Recurring themes in the answers
The brands AI favors share dermatologist-developed positioning, ceramide or barrier-repair formulation, fragrance-free and non-comedogenic labeling, and wide US drugstore availability.

All four engines return the exact same three brands in their top 3 - CeraVe, La Roche-Posay, and Vanicream - merely permuted, which is the tightest three-brand consensus in the dataset. The aggregate #1 splits two-to-two: La Roche-Posay leads for ChatGPT and Gemini, CeraVe leads for Claude and Perplexity, and whichever is not first is second or third in every case.

Perplexity is the most citation-driven and consolidated, uniquely surfacing Drunk Elephant, Tatcha, and Blue Lizard. The prestige tier is where the engines diverge most: three of four exclude prestige brands from the top ranks entirely.
Every engine converges on the same routine architecture - gentle cleanser, vitamin C in the morning, retinoid at night, and sunscreen as the single most-emphasized anti-aging step - and every engine independently tells the buyer to introduce one active at a time and to skip toners, eye creams, and scrubs.
CeraVe owns affordable barrier basics, La Roche-Posay the sensitive-skin clinical-but-accessible slot, Vanicream the reactive-skin safe haven, EltaMD the acne-safe sunscreen slot, and SkinCeuticals the splurge antioxidant slot.
Every engine also recommends mixing brands rather than staying loyal to one.
