The Revele Jade Facial Roller is a gentle massager which helps to depuff the face and under the eye area while revitalizing skins elasticity. It's best to use the larger end of your roller for your cheeks, neck, and forehead, and switch to the small end for your nose and under-eye area. But before you start rolling, you'll want to make sure your skin is clean and freshly slathered with your favorite serum or moisturizer. Gua Sha is a massage technique designed to relieve tension in the muscles of the face, boost blood circulation, and encourage lymphatic drainage to banish bloat. It helps break up fascia, the connective tissue that hugs muscles but can sometimes interfere with optimal circulation.When you're done, always wash the roller and dry it for sanitation purposes.
