Summary

emollient skin conditioning

Science

Mechanism of Action

As an ester of ricinoleic acid, Methyl Acetyl Ricinoleate integrates into the skin's surface, acting as an effective emollient. It works to improve skin's suppleness and texture by forming a protective layer that helps reduce trans-epidermal water loss. This action results in enhanced skin conditioning, promoting softness and smoothness, while potentially offering moisturizing and soothing properties.
