Working theory

1. Skin tighten rolller is designed to come into contact with delicate skin every day.

2. Surfaces are platinum-coated. 

3. The two rollers emit a virtually imperceptible microcurrent, a slight electrical current that helps        restore the natural tightness of the mesh of the skin texture, which in turn leads to tautness and sheen.

4. It generates a microcurrent as a function of the magnetic rings integrated within the solar panels and rollers.

Features:

1. The roller surfaces are coated with platinum. The sheen of the platinum coating is long-lasting because platinum resists deterioration or discoloration.

2. Inside the rollers, there are ceramic rings composed of 16 different types of natural ores.

3. It is waterproof, so it can be used while taking a bath. 

4. Materials used in the device: ABS resin, stainless steel, brass, acrylic, silicone rubber, ceramic rings, magnet, platinum.
