Will you check the ingredients when you purchase the cosmetics? I wonder if you find betaine in it,maybe you donn’t know what it is and what’s its function. Let’s talk about betaine.

Betaine acts as a gentle hydrator like glycerinum that helps you skin gain and maintain moisture,but the chemical molecular structure between of them is different,betaine allows water molecules to be fully absorbed and utilized by living cells.When a water molecule occupied between the amphoteric ions of betaine, it can easily release its own water molecules into the surrounding liquid.So betaine is superior to other moisturizers in moisturizing mechanism and can keep moisture for a long time even at low concentration.

When the skin is subjected to high osmotic pressure of the external environment, it will make a large amount of osmotic substance loss, resulting in cell apoptosis.Betaine permeate inhibits this process and penetrates through the cuticle of the skin to protect cell balance.Betaine added into shampoo can reduce the stimulation effect of surfactants on the scalp, and also can improve the itch hair and dry hair after washing.
