About

A plant cell wall glycoprotein hydrolyzate providing amino acids and polysaccharides for skin hydration and barrier support.

Hydrolyzed Extensin is produced by hydrolyzing extensins, which are plant cell wall hydroxyproline-rich glycoproteins (HRGPs). Extensins are structural proteins found in all higher plants; hydrolysis breaks them into smaller peptides and amino acids suitable for cosmetic use. No specific EU restrictions apply; hydrolyzed plant proteins are widely used in skincare for their moisturising and barrier-supporting properties.

Skin benefits

  • Amino acid source for skin
  • Moisture retention
  • Skin barrier support

Known concerns

  • Generally very safe; rare allergic reactions possible in individuals sensitive to specific plant proteins
