Why this verdict
Water/glycol root extract - inulin polysaccharide + arctigenin/arctiin lignans; documented antimicrobial activity against Malassezia spp. isolates (in vitro), no fatty acid content.
Fungal acne, properly called malassezia folliculitis, is driven by a yeast that feeds on fatty acids in roughly the C11 to C24 range. An ingredient is a concern when it can supply usable fatty acids in that window, and it is generally fine when it cannot. Chain length and ethoxylation can both change the verdict, which is why the chemical family alone does not decide it. See the full trigger list and how we assess ingredients for the reasoning and sources.

Why is Arctium Lappa Root Extract considered fungal-acne safe?
Water/glycol root extract - inulin polysaccharide + arctigenin/arctiin lignans; documented antimicrobial activity against Malassezia spp. isolates (in vitro), no fatty acid content. Fungal acne (malassezia folliculitis) is driven by ingredients that supply fatty acids in roughly the C11 to C24 range that the yeast can metabolize; Arctium Lappa Root Extract is assessed against that mechanism.
