A beautiful quality tool that can be used both on the face and body. I have all three of the Refa Carat Rollers. I use the Refa Carat Ray on the body, it’s perfect for the thighs and upper arms and shoulders. The Refa Carat Ray Face is amazing for facial massage and really makes a difference if used regularly. I would also recommend the smaller Refa Carat Ray S as this is brilliant for depuffing the eyes and toning the upper eye area. I love the fact that you don’t need to charge or use batteries or use any specials gels or creams as the micro current works via the solar panel. I like to use the rollers with a little facial oil but they can be used with your usual regular creams and serums and the face and S rollers are lovely when used over a sheet mask.
