Key takeaway
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 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.

Neutrogena has a mention count of 6 but is outside the displayed comparison. Mention frequency and response rank measure different things.

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.
Findings and Limitations
- 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.
Recurring themes in the answers
- 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.

ChatGPT · Prompt 1Usable answer
I'm a 32-year-old woman in the USA with combination skin who works full-time and wants a simple, effective routine for early fine lines, dullness, and occasional breakouts, looking for the best skincare. What would you recommend?
For your goals, I'd keep it boring, consistent, and evidence-based rather than building a 10-step routine. At 32, the biggest wins are daily sunscreen, a retinoid at night, and enough moisturizer to keep your barrier happy. Retinoids can address fine lines, uneven tone/texture, and mild acne; vitamin C is a useful morning addition for dullness and dark spots. American Academy of Dermatology +1 My ideal routine for you Morning - 3 - 4 steps Gentle cleanser If you're oily in the morning: CeraVe Balancing Air Foam Facial Cleanser If you're more normal/dry in the cheeks: you can simply rinse with water. Vitamin C serum A good, reasonably priced choice: CeraVe Skin Renewing Vitamin C Serum - 10% vitamin C. Apply after cleansing and before sunscreen. AAD specifically recommends vitamin C in the morning. American Academy of Dermatology Lightweight moisturizer Look for ceramides, glycerin, hyaluronic acid, and "non-comedogenic." You don't necessarily need a separate moisturizer if your sunscreen is moisturizing enough. Broad-spectrum SPF 30 - 50+ every day This is the most important anti-aging step. UV exposure accelerates wrinkles and pigmentation. American Academy of Dermatology +1 One option: CeraVe Invisible Mineral Sunscreen SPF 50 Face Lotion. If you dislike mineral sunscreen, choose a comfortable broad-spectrum SPF 30+ that you'll actually use every day. Evening - 2 - 3 steps Cleanser Same cleanser as morning. Retinol - start 2 nights/week This is the ingredient I'd prioritize for your combination of early fine lines + occasional breakouts + dullness. Start with a low-strength OTC retinol rather than jumping into an aggressive product. AAD recommends starting a retinoid slowly because irritation can undermine results. American Academy of Dermatology Use a pea-sized amount for your entire face, avoiding the immediate eye corners and creases around the nose/lips. After a few weeks, if your skin is comfortable, increase to every other night, eventually working toward nightly use. Moisturizer Apply after retinol - or before retinol if you tend to get irritated ("sandwiching"). What about your breakouts? Don't automatically add several acne acids. Your retinoid is already doing double duty. If you occasionally get clogged pores, you could add salicylic acid 1 - 2% once or twice weekly, but I'd introduce it only after your skin has adapted to retinol. Gentle skincare is preferable to aggressively scrubbing or repeatedly exfoliating acne-prone skin. American Academy of Dermatology +1 Your "busy working woman" version If you want the absolute minimum: Morning Evening Cleanser Cleanser Vitamin C Retinol SPF 50 Moisturizer That's genuinely enough. You don't need toner, essence, eye cream, facial oil, exfoliating pads, or multiple serums to get excellent results. A few important rules Introduce one new active at a time. Give it several weeks before deciding it isn't working. Don't chase the strongest percentage. Irritated skin isn't more effective skin. Moisturize even with combination skin. The goal is balanced skin, not squeaky-clean skin. American Academy of Dermatology SPF every morning, including days you're mostly indoors if you're getting meaningful daylight exposure. If you're pregnant or trying to become pregnant, skip retinoids/retinol and discuss alternatives with your clinician. American Academy of Dermatology +1 If I were spending your money, I'd put the most effort into finding a sunscreen you love wearing and a retinol your skin tolerates - not buying expensive "anti-aging" products. A simple routine you use consistently will beat a luxurious routine you abandon after three weeks. If you tell me your budget (e.g. <$50, <$100, or no limit), whether your skin is sensitive, and whether you prefer drugstore/Sephora/Ulta, I can narrow this down to an exact 5-product shopping list with specific products.Frequently Asked Questions
