Pore-clogging ingredients in sunscreen

When sunscreen breaks you out, the UV filters are rarely the problem: zinc oxide and titanium dioxide rate 0, and chemical filters aren't flagged either. The trouble is the base: dissolving and spreading filters evenly takes a lot of ester, and sunscreens lean on exactly the ones with high comedogenicity ratings.

Ethylhexyl palmitate and ethylhexyl stearate are near-ubiquitous in SPF formulas; shea butter and coconut derivatives are common in 'reef-safe' mineral ones. These are the sunscreen-relevant ingredients our checker flags, worth scanning for since sunscreen is a daily, leave-on, full-face product.

Ratings come from published comedogenicity research and esthetician-maintained lists. They are imperfect and formulation-dependent, and this page isn't medical advice. Last reviewed 2026-08-15 by the PorePass editorial team.
