Exact science-based dupes appear first. When a strict dupe is not available yet, we still show the closest active-match alternatives from the same product category.

La-roche-posay · drugstore
Overlaps on bis-ethylhexyloxyphenol methoxyphenyl triazine, ethylhexyl triazone, butyl methoxydibenzoylmethane, and ethylhexyl salicylate, but adds octocrylene and titanium dioxide as extra actives not matched in dose to the source.
No price

La-roche-posay · drugstore
Shares bis-ethylhexyloxyphenol methoxyphenyl triazine, butyl methoxydibenzoylmethane, ethylhexyl salicylate, and diisopropyl sebacate, but swaps in diethylhexyl butamido triazone and terephthalylidene dicamphor sulfonic acid instead of ethylhexyl triazone/isoamyl p-methoxycinnamate.

Mixa Solaire · drugstore
Matches on bis-ethylhexyloxyphenol methoxyphenyl triazine, butyl methoxydibenzoylmethane, and ethylhexyl salicylate, but relies on diethylhexyl butamido triazone rather than ethylhexyl triazone/isoamyl p-methoxycinnamate, so the filter combo isn't identical.
No price

Mixa · drugstore
Shares bis-ethylhexyloxyphenol methoxyphenyl triazine, ethylhexyl triazone, and butyl methoxydibenzoylmethane with the source but lacks ethylhexyl salicylate and isoamyl p-methoxycinnamate, and uses a different filter (phenylbenzimidazole sulfonic acid) not in the source.

Summer Fridays · drugstore
This is a mineral-only sunscreen built around zinc oxide with none of the source's organic filters (avobenzone, ethylhexyl triazone, bis-ethylhexyloxyphenol methoxyphenyl triazine, etc.), so despite shared antioxidants it works on a totally different UV-filter mechanism.

We rank results with INCI-level analysis first, then fall back to the strongest active matches and closest alternatives so every product page still shows comparable options. Fallbacks stay within the same category as the source product, so cleansing balms only surface cleanser dupes instead of adjacent product types. Active Match % measures shared science-backed actives. Formula Similarity % measures total ingredient overlap when full INCI lists are available.
