Why we built SPF Scout
Sunscreen labels are long and the print is small. Scan the barcode and SPF Scout lays out every ingredient, what each one does, and which of them you asked to flag.
Published 21 October 2026
A sunscreen's Drug Facts panel can list 30 ingredients or more, in small type on a curved bottle, under names like Butyloctyl Salicylate and Caprylyl Glycol. If there is one ingredient you would rather skip, finding it means reading every line, on every bottle, in the store aisle.
We built SPF Scout so that takes seconds instead.
Scan the barcode, see the list
Point your phone at the UPC on the box or bottle. SPF Scout pulls up the full ingredient list stored for that U.S. sunscreen, with where the list came from and the date it was retrieved. No barcode handy? Search by brand or product name instead.
See what each ingredient does
Every name on the list carries its role in plain words: UV filter, emollient, humectant, preservative, and so on. Tap a name for a short note on what it generally does in a formula. The same notes are on the website, for example Zinc Oxide.
Flag what you choose to avoid
You decide what gets flagged. Turn on added fragrance. Pick a whole group, such as parabens, isothiazolinones or formaldehyde releasers, or search for any single ingredient by name. Every time you scan, SPF Scout shows which of your picks appear on the label.
When a label prints a blend as one word, Fragrance or Parfum, the individual components are not named. SPF Scout tells you the components are not disclosed, so you know that line could hold something it cannot check against your picks.
Spot the mineral filters
Mineral sunscreens rely on zinc oxide, titanium dioxide, or both. Every UV filter is named on the result, so you can see at a glance whether a sunscreen lists only mineral filters, only organic ones such as avobenzone and octocrylene, or a mix of the two.
What it does not do
SPF Scout does not rank sunscreens or pick one for you, and it cannot tell how your skin will respond. It reports what the label lists and compares that list with the ingredients you chose. Formulas change, so compare the record with the package in your hand, and if something does not match, tap Report incorrect formulation and we will look into it.
If you have an avoidance list from a clinician, SPF Scout is a faster way to check labels against it. It does not replace their advice.
This result compares the currently stored ingredient list with ingredients you selected. It is not a prediction of whether your skin will react.
