About
Japanese climbing fern spore — a traditional East Asian powder used for gentle exfoliation. Cosmetic data is thin.
Lygodium japonicum spore (hai jin sha) is a traditional Chinese Materia Medica ingredient. As a cosmetic it appears as a fine natural spore powder used for gentle physical exfoliation and oil absorption in masks and cleansers. Listed in EU CosIng under exfoliant/abrasive function but without a dedicated SCCS opinion. Modern safety data is limited and largely extrapolated from related fern spores. Key practical concerns are inhalation during manufacturing, potential microbial load if not properly treated, and rare fern-family sensitisation. Evidence level low; conservative use is warranted.
