Betaine, also known as trimethylglycine , glycine betaine , or beta-alanine derivative , is a natural active ingredient primarily derived from sugar beets . In skincare, betaine is particularly valued for its intensely moisturizing, soothing, and skin-smoothing properties . As an osmolyte, it regulates the water balance in skin cells, protects against moisture loss, and helps the skin maintain its natural protective barrier. Betaine is gentle, very well tolerated by the skin, and therefore also suitable for sensitive or stressed skin.
