About

A traditional fiber seed from New Zealand flax — provides skin-conditioning compounds and is historically used for wound care, though it's not widely studied in cosmetic science.

Phormium tenax (New Zealand flax, harakeke) seed contains fixed oils dominated by linoleic acid, oleic acid, and palmitic acid, along with polysaccharides and lignans. The plant has a long history in Māori traditional medicine for treating wounds, burns, and skin infections, applied both as a poultice and as a wash. The seeds specifically are less documented than the leaves, but the lipid fraction contributes emollient properties and the historical use supports a role in skin repair. Safety data for topical use is limited but the traditional use record is strongly positive.

Skin benefits

  • Emollient from fatty acid-rich seed oil
  • Traditional wound-healing agent
  • Anti-inflammatory from lignan content
  • Skin conditioning

Known concerns

  • Limited modern cosmetic safety data
  • Possible cross-reactivity with other Phormiaceae family members
  • Generally well-tolerated based on traditional use
