Ingredients to avoid in sunscreen: what the data shows
Updated 2026-10-15 · Based on 1750 screened products
"Avoid" lists online mix two things: ingredients with a regulatory or IARC basis, and ingredients that are debated (often UV filters). We separate them. Wear sunscreen either way; the FDA – Sunscreen: How to Help Protect Your Skin from the Sun and dermatologists recommend broad-spectrum SPF 15+.
1. Watchlist flags in 115 sunscreens
| Watchlist group | Products flagged |
|---|---|
| Titanium dioxide | 36 |
| Butylphenyl methylpropional / Lilial | 6 |
| Parabens | 5 |
| Talc | 1 |
Most flags are titanium dioxide, classified by IARC for inhaled powder, which matters most for sprays and loose powders rather than lotions.
2. Debated UV filters (not on our watchlist)
These are legal in the EU within limits set after EU Scientific Committee on Consumer Safety (SCCS) opinions. We report how often they appear in our data:
| Ingredient | Sunscreens listing it | EU status |
|---|---|---|
| Oxybenzone (benzophenone-3) | 3 of 115 | EU max 6% in sunscreens, 0.5% elsewhere (Reg. 2022/1176) |
| Octocrylene | 29 of 115 | EU max 10% (Reg. 2022/1176) |
| Homosalate | 17 of 115 | EU limit lowered to 7.34% in face products (Reg. 2022/1176) |
| Octinoxate (ethylhexyl methoxycinnamate) | 9 of 115 | EU-permitted UV filter (Annex VI), max 10% |
| Avobenzone (butyl methoxydibenzoylmethane) | 57 of 115 | EU-permitted UV filter (Annex VI), max 5% |

Where to look next
Hazard is not risk. An IARC classification says whether a substance can cause cancer under some conditions (e.g. titanium dioxide is classified for inhaled powder), not that a cosmetic containing it is harmful at normal use. EU restrictions set use limits. This page is informational, not medical advice; talk to a dermatologist about your own skin.
