The hydrolysed form supplies oligosaccharide fragments (carrageenan-derived oligogalactans and 3,6-anhydro-L-galactose) that bind water at the stratum corneum surface and form a brief hygroscopic film during the wear window. Kappa-carrageenan tetrasaccharide supports stratum corneum hydration and transepidermal water loss balance in keratinocyte models\u003csup\u003e1\u003c\/sup\u003e. 3,6-anhydro-L-galactose supports endogenous hyaluronic acid synthesis in HaCaT keratinocytes\u003csup\u003e3\u003c\/sup\u003e.
