Betaine is a well-known ingredient for its osmolytic action, which helps skin adapt to humidity fluctuations while maintaining optimal hydration balance. Thanks to its ability to retain water, it is ideal for preventing dehydration and improving skin softness and elasticity.
This substance is widely used in cleansing formulations, where it acts as a soothing agent, reducing the irritant potential of surfactants and making products gentler even for sensitive skin. Its versatility also extends to hair care, where it acts as a conditioning agent, improving softness and manageability.
