Algiert-Zielinska B, et al. - Researchers performed a comparative evaluation of hydration level (corneometric) following application of lactobionic acid (LA) in the form of peel at concentrations of 10% and 30%. They applied the peels using the “Split face” method-on the left side of the face 10% LA, and the right side 30% LA which consisted of specified concentration of LA, deionized water, xanthan gum, ethoxydiglycol. Findings suggested that lactobionic acid was a highly moisturizing agent. Between 10% LA concentration and 30% LA concentration, no significant difference in moisturizing effect was seen.
