We gave 5 of the world's top AIs—including GPT-5, Claude, and Gemini—one mission: rank the best bar soaps after analyzing thousands of 2025 reviews and debating key factors like hydration, sensitivity, and eco-friendliness. Here's their consensus verdict on what truly cleanses and cares.
No.1 AI-Picked Product
We had 5 AI models rank their top 5 products. We tallied the scores. Here's the winner with the highest score.
CeraVe Hydrating Cleanser Bar
The CeraVe Hydrating Cleanser Bar was ranked #1 by 3 out of 5 AIs, with an average rank of 1.33 across appearances. It won for its ceramide- and hyaluronic acid-enriched formula that gently cleanses without stripping moisture, ideal for sensitive and dry skin, earning praise for being fragrance-free and dermatologist-recommended. This bar's non-comedogenic properties and recyclable packaging sealed its top spot in 2025's barrier-focused trends.
What Each AI's Top Pick:
