The Chinese have been using these beautiful crystal rollers to massage skin since the 17th Century. They are known to remove toxins from the skin, smooth fine lines, decrease under eye bags and dark circles, calm inflamation, heal breaks out, brighten skin. They have also been known to help reuce swelling by assisting the lympatic drainage in the face. We simply love them becuase they create an overall zen feeling and who can't appreciate that? Apply a few drops of one of our facial lotions, serums or facial oils to a dry, clean face. Roll up, down and sideways until all the product is absorbed. Feel Amazing!
