Elina-Med Jade Roller for face and neck An original roller made of 100% original New Zealand jade (Gaston). Jade is a gemstone with multiple benefits for the skin as it improves blood circulation and activates skin cells to produce collagen, due to the fact that Jade stone shines and diffuses a kind of infrared radiation. The jade stone can be used by rotating the stone roller directly on the face and neck, or placing face creams (preferably using Alina-Med creams) on the roller and then rolling it on the skin of the face and neck. It also reduces the amount of cream used. It should be known that there is a difference between the original jade stone (it is considered an expensive gemstone as it is used in jewelry, beads and antiques) and the imitation stone, which is often an ordinary stone or made of glass. The most important features of the original New Zealand green jade stone is that it has two shades of light and dark green, and is characterized by the presence of pores in it, and there are also black dots on it. And most importantly, you must choose the source or the reputable company that manufactures the roll. The original jade stone can also be known as being cold, and after using it, it gives off a kind of heat and then comes back cold again. The original jade stone is cleaned from the cream by alcohol (spiro). The original jade stone retains its color and properties after use, while the imitation stone loses its color after use for a certain period.
