Seaweed & Marine Algae

aka sea kelp · kelp · sugar kelp · saccharina latissima

The marine botanical category — kelp, dulse, sea fennel, fucus, chondrus — built into a brand identity by Osea, La Mer (its origin myth), and Salt + Stone. Polysaccharide-rich (alginate, fucoidan, carrageenan) for humectancy and film-forming, plus unique marine minerals and amino acids. Sustainably farmed sea kelp is now a Blue Beauty supply story.

Benefits
  • polysaccharide humectancy via alginate and fucoidan
  • marine mineral and amino acid profile
  • regenerative ocean farming as supply story
Example uses
  • marine hydrators (Osea)
  • body deodorants (Salt + Stone)
  • regenerative-sourcing hero products
Formulation notes

Cold-extracted to preserve polysaccharide structure. Pairs with HA, glycerin, and ceramides in marine-positioned hydrators. Rotates well with land botanicals for sensorial differentiation.

Watchouts

Heavy metal accumulation is a real risk in some harvest regions — supplier testing is essential. 'Sea minerals' is often sea salt at trace levels.
