GLYCERIN

Glycerin is a substance found naturally in skin, skin-replenishing and skin-restoring.

It functions as a humectant – a type of moisturising agent – which works by attracting and retaining water from the atmosphere to hydrate the outermost layer of the skin, called stratum corneum. This properties of Glycerin helps to maintain skin moisture, improve skin elasticity and prevent dryness and roughness.

The moisturizing action of Glycerin involves its interaction with the skin’s natural moisturizing factor (NMF). The NMF comprises various substances, such as amino acids, lactate, urea, and sugars, which are responsible for maintaining the skin’s hydration balance. Glycerin acts as a hygroscopic agent by attracting water molecules from the surrounding environment and binding them to the components of NMF, resulting in enhanced water retention within the skin.

Additionally, Glycerin plays a crucial role in improving the skin’s barrier function. It strengthens the intercellular lipid matrix of the stratum corneum, which acts as a protective barrier against environmental stressors and helps to prevent water loss from the skin. By reinforcing the barrier function, glycerin helps to maintain the skin’s integrity and protect it from external irritants and pollutants.
