Betaine is a substance synthesized in the human body. But a major advantage is the fact that it is obtained in a fully natural way, without the need for artificial synthesis. Its name comes from the Latin name of red beets, which are an excellent source of it and through which it was discovered. However, it is also obtained from sugar beets as well as coconuts. In the human body, betaine is produced in parallel with vitamin B4. In cosmetics, betaine has hydrophilic properties, making it a natural humectant. When applied to the skin, it strongly moisturizes and helps maintain the water-lipid balance. That is why it is a commonly used ingredient by natural cosmetics manufacturers for skin and hair care.
