Skincare Check, the ingredient-list referee

Field notes

The site organizes its database around six explicit ingredient rules rather than a broad safety score. Its definitions are concrete: fragrance-free excludes Parfum and declared fragrance allergens, sulfate-free names SLS and SLES, and alcohol-free excludes drying alcohol while leaving fatty alcohols out of the test. The homepage also exposes recent lookups, an ingredient dictionary, and aggregate pass counts, so the service functions as both a lookup tool and a browsable reference.
