● Features
Contains the maximum concentration of active ingredients effective for severe eye fatigue※
It is said that we obtain much of our information through our eyes. In modern society, where information technology has advanced, environments that overuse the eyes have increased. In such environments, the eye's focusing adjustment function declines, making it easy to experience eye fatigue, a heavy, dull feeling deep in the eyes.
Sante Medical 12 is an eye fatigue improvement eye drop that thoughtfully combines 12 types of active ingredients in a well-balanced manner, including four ingredients such as vitamin B12 and neostigmine methyl sulfate, which are effective for improving eye fatigue, at their maximum concentrations※. It works on the focusing adjustment muscles and the parasympathetic nervous system to enhance the weakened focusing adjustment function, moisturizes dry eyes, and further nourishes the eyes to promote tissue metabolism function. It supports a "healthy and clear" life for those living in modern society who overuse their eyes.
※Maximum concentration according to the standards for approval of general ophthalmic drugs: vitamin B12, neostigmine methyl sulfate, chondroitin sulfate ester sodium, chlorpheniramine maleate
