Algae/Seaweed/Kelp (Species Unspecified)
What is Algae/Seaweed/Kelp (Species Unspecified)?
Algae, seaweed, and kelp encompass diverse marine macroalgae species sourced from oceans globally, including brown, red, and green varieties. These botanical extracts are obtained via mechanical processing or aqueous extraction, yielding polysaccharides like alginates, carrageenans, and fucoidans, alongside minerals and trace elements. In cosmetic formulations, they serve as skin conditioning agents in moisturizers, masks, serums, and cleansers. Their primary function involves humectant and film-forming actions, which draw moisture to the skin, create a breathable barrier, and promote suppleness by interacting with the stratum corneum. This helps counteract environmental stressors while supporting the skin's natural lipid balance without clogging pores.
