Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

Ground wakame holdfast — a seaweed powder loaded with fucoidan and minerals. Antioxidant and hydrating, with a long food history.

Undaria Pinnatifida Root Powder is the dried and ground holdfast (root-like anchoring structure) of wakame, a brown edible kelp widely consumed in East Asian cuisine. It contains fucoidans, alginates, laminarins, and minerals (calcium, magnesium, iodine). Fucoidan is a sulfated polysaccharide with well-documented antioxidant, anti-inflammatory, and skin-soothing activity in cosmetic research. EU CosIng lists Undaria extracts as skin-conditioning agents. Seaweeds can accumulate heavy metals and iodine from seawater, so reputable suppliers test and certify; at typical cosmetic use concentrations topical iodine exposure is negligible.

Skin benefits

  • Fucoidan antioxidant activity
  • Mineral-rich conditioning
  • Polysaccharide hydration
  • Gentle soothing effects

Known concerns

  • Natural iodine — rare sensitivity
  • Heavy-metal accumulation in seaweed — quality-control dependent
  • Batch composition variability
