Allergens in sunscreens: 726 products analyzed
Sunscreen is the category people assume is "clinical" — yet it leads our catalog in fragrance-allergen exposure, because so many formulas add scent to mask the smell of UV filters.
Based on 4,442 products with parsed ingredient labels in the AllerNote catalog, as of 2026-07-16.
What stands out
Two things drive sunscreen's numbers. First, the base chemistry: UV filters and their solvents smell, so brands routinely perfume the formula — which is how limonene, linalool and friends end up in a product you apply over your whole face every single day. Second, the "beach" positioning: consumer sunscreens are scented like a holiday, while pharmacy and Asian-market sunscreens are far more likely to be genuinely fragrance-free.
If you're patch-tested positive to a fragrance allergen, sunscreen deserves more scrutiny than almost anything else in your routine — daily use, large surface area, reapplication, and sun-damaged skin all raise the stakes. The good news: the fragrance-free share of this category is substantial, so switching rarely means giving up texture or finish.
