👁️ Product Overview
Rohto Yojunsui α is an eye drop designed with the concept of restoring eye fatigue from daytime strain through "nighttime recovery power." Chondroitin sulfate ester sodium retains moisture on the corneal surface, taurine promotes metabolism, natural type vitamin E promotes blood circulation to relieve eye fatigue, and L-aspartic acid potassium enhances cellular respiration.
Additionally, sodium hyaluronate, well known as a moisturizing ingredient in beauty serums, is included as an additive, enveloping the eyes with excellent moisturizing viscosity. The mild stimulation with cooling sensation level 2 makes it easy to use before bedtime, and the free-angle nozzle and one-touch screw cap allow easy application even in the dark.
