Effect of betaine on moisturizing and protecting cell membrane

Organic osmolytes are a kind of chemical substances that maintain the metabolic specificity of cells and resist the osmotic working pressure to stabilize the macromolecular formula. For example, sugar, polyether polyols, carbohydrates and compounds, betaine is a key organic permeable substance.

Existing scientific research shows that the higher the dryness or salinity of the natural environment, the higher the betaine content in microbial cells.


Skin cells change the concentration of osmolyte in cells according to the accumulated or released organic osmolyte, so as to dynamically maintain the volume and water balance of cells.

When the external high osmotic working pressure, such as skin epidermal dehydration or ultraviolet radiation, will cause a lot of outflow of osmotic substance in skin cells, resulting in apoptosis of outer skin cells, and betaine osmotic substance can significantly inhibit the whole process.

When betaine is used in personal care products, it is used as an organic penetrant to maintain the penetration balance of cells according to the penetration into the cuticle of the skin, so as to improve the moisture content of the surface skin. The unique moisturizing principle of betaine makes its moisturizing characteristics different from common moisturizers.


Compared with hyaluronic acid gel, beet even at low concentrations can still have the actual effect of long-term moisturizing.

French L’Oreal’s Vichy fountain deep moisturizing product adds such ingredients. Its “tap water” deep moisturizing advertising claims that the product can attract the deep-seated moisture of the skin to the skin with less water, so as to promote the surface skin with sufficient water.
