Amazon: ¥3680 idio Facial Roller: Dermatologist-Recommended Microcurrent, Small Face Roller, Weak Current, Diamond Cut, No Charging Required, Solar Panel Equipped The idio facial roller is a roller beauty device that we propose with the concept of skincare, developed by us who have been particular about "things that are truly good for the skin" and have developed basic cosmetics. The main feature of the idio facial roller, co-developed with dermatologists, is microcurrent. This is an extremely weak current, similar to the bioelectric current, widely used in medical and aesthetic treatments. Without hardly feeling any electrical stimulation, it relaxes the muscles and leads to firm skin. It reproduces the techniques of gently and accurately relaxing muscles, just like the fingertips of an esthetician. With a Y-shaped roller shape that conforms to the curves of the skin, it is possible to intensively care for areas of concern. [No Charging Required with Solar Panel] It takes in natural light to generate microcurrent, realizing delicate massage. The surface of the massage roller uses a platinum coating that emits a beautiful shine. The waterproof, water-proof structure that can be used in the bathtub is also a nice point. Gently roll the roller back and forth along the lines of the face and body. You can use it not only for the face line, but also for the neck, décolleté, upper arms, waist, and leg care.
