Prepare sensitive and troubled skin to "always be in good condition" For those who have skin that is hypersensitive to unnecessary ingredients in cosmetics and those who want to aim for firm skin. While blending a high amount of ingredients that support ceramides, such as pycnogenol derived from the bark of the French coast and amino acids that make up collagen such as AHP and HP, the burden on the skin is removed as much as possible, and only water and beauty ingredients are completely additive-free = 7 free (no preservatives, petroleum-derived ingredients, surfactants, colorants, fragrances, ethanol, polyhydric alcohol BG, glycerin, etc.). By adopting a unique low-temperature heat sterilization method that has never been used before, and an aerosol container that does not allow air and bacteria to enter during use, it is devised so that it can be used freshly until the end.
