How it works in skincare

In cosmetics and skincare, betaine functions as a humectant and conditioning agent that attracts and binds water to the skin and hair. It enhances the performance of formulas by reducing irritation from surfactants, improving spreadability and delivering a soft, smooth after-feel. You will often find it in cleansers, moisturisers, shampoos and conditioners where it works to support the skin barrier and boost overall hydration levels.
