With an additional sugar molecule attached, lactobionic acid is more hydrating and even more gentle than another common form of PHA - gluconolactone, making lactobionic acid the more premium one of the two common PHAs.

Comparing to AHAs, lactobionic acid has a larger molecular size and weight, therefore, its’ potential for increased hydration is attributed to humectant properties of the multiple hydroxyl groups (-OH), which can attract and hydrogen bond water.
