Another ingredient of the Yeast Brightening Moist Serum - the NMF. The NMF is a mixture of powerful humectants such as glucose, sorbitol, urea, PCA, glycerin, lactic acid, hydrolyzed wheat protein and panthenol, etc. In fact, the NMF, present at the outer layer of the skin, protects and hydrates the skin through drawing water from the atmosphere into the corneocytes. This process can occur even in a relatively low-humidity environment so as to maintain an adequate level of water. The NMF dissolves into the water and its ionic interactions with keratin fibers increases the elasticity of the stratum corneum, makes the skin healthy and supple, and prevents it from cracking or flaking.
