The ChatGPT Shelf for Sunscreen

Blue Lizard outranks Neutrogena

La Roche-Posay leads at 62%, then CeraVe at 47% and Blue Lizard at 46% — a pharmacy-shelf brand a lot of people have never heard of, sitting 10 points ahead of Neutrogena. Where the offers come from says as much: Ulta supplies more of them than Walmart or Target, and CVS accounts for 8%.

Who ChatGPT names

Share of shelf is the percentage of answers a brand appeared in. It is not a rank of quality or sales — it is how often the model brought the brand up when someone asked about sunscreen.

  1. 1 La Roche-Posay 62%
  2. 2 CeraVe 47%
  3. 3 Blue Lizard 46%
  4. 4 Supergoop! 40%
  5. 5 EltaMD 37%
  6. 6 Neutrogena 36%
  7. 7 Eucerin 26%
  8. 8 Bioré 22%
  9. 9 Banana Boat 16%
  10. 10 Sun Bum 12%

Where the offers come from

Every product ChatGPT showed came from somewhere. Brand-direct means the offer pointed at the brand's own store rather than a retailer.

  • Walmart 27% · 1,193 offers
  • Target 21% · 917 offers
  • CVS 8% · 359 offers
  • Sephora 6% · 274 offers
  • Brand-direct 1% · 44 offers

How the shelf gets built

How we measured this

  • We asked ChatGPT 1,218 shopping questions about sunscreen in July 2026. The questions never named a brand, so nothing here was prompted into the answer.
  • Questions were repeated. ChatGPT does not answer the same way twice, so a single ask tells you nothing — share of shelf is the pattern across all 1,218 of them.
  • We recorded every brand mentioned and every product offer shown, 5,426 offers across 145 brands.
  • This is one engine, one country, one point in time. It is a snapshot of a shelf that moves.
