About
A ferment of humus (soil-derived organic matter) by Cryptococcus yeast. Used for antioxidant claims; the chemistry is plausible but the obscure substrate and lack of public safety data hold the score down.
Skin benefits

- Antioxidant phenolic and humic acids
- Trace minerals from humus substrate
Known concerns
- Humus is a heterogeneous substrate — composition varies
- Cryptococcus species are usually non-pathogenic but require sterility check
- No public CIR/SCCS dossier
