Key Ingredients ■ 5 Types of Human Ceramide Ceramides are the main component of "intercellular lipids" that prevent moisture evaporation from the stratum corneum. They have a barrier function for the skin and play an important role in protecting it from external stimuli. There are multiple ceramides present in the stratum corneum. To get closer to them, we have blended 5 different types of ceramides with different functions. ■ Surfactin Na A low-irritation, biodegradable natural surfactant. Gently removes sebum and makeup. ■ Soybean Oil Replenishes oil, prevents moisture evaporation, retains moisture, and provides flexibility. I think it will be shipped with only water damage protection in an OPP bag. Please consider this before purchasing.
