Betaine is a natural amino acid derivative often sourced from sugar beets, making it a gentle yet highly effective hydrating and soothing ingredient in Korean skincare (K-beauty). Known for its ability to balance skin’s moisture levels, protect against irritation, and improve skin softness, Betaine is especially valued in formulations designed for dry, sensitive, and combination skin.
In K-beauty products, Betaine is often paired with Hyaluronic Acid, Panthenol, or Centella Asiatica to deliver deep hydration without heaviness. Its lightweight texture makes it an excellent addition to toners, essences, serums, and creams, helping to keep the skin plump, smooth, and comfortable all day long.
