SlipperSkin finding

Part of our study of how ingredient apps disagree, now 88 products from 48 brands. Every figure below links to the page it was read from.

EWG Skin Deep scores hazard from 1 to 10 (1 to 2 is its low band); INCIdecoder names the ingredients it rates "icky"; SkinSAFE rates freedom from common allergens (100 is its top); Skincarisma scores from EWG's ingredient ratings out of 100. 1 of 2 get SkinSAFE's top rating.

Which listings may be out of date?

Formulas change and databases keep the list they were given. Where one database's ingredient list differs from the others on a clear marker (parabens or fragrance), or EWG labels its listing with a formulation year, we show it here as a question, not a finding: a majority of published lists is evidence, not proof of the current formula.
