Algiert-Zielinska B, et al. - This research was designed in order to comparatively explore the hydration level (corneometric) of skin after the application of lactobionic acid (LA) in the form of peel at concentrations of 10% and 30%. Data revealed that lactobionic acid was a highly moisturizing agent. No notable variation was discovered in the moisturizing effect between 10% LA concentration and 30% LA concentration.
