The Rose Quartz Facial Roller lessens visible puffiness while boosting blood flow and promoting oxygenation of the skin's deeper layers. This, in turn, aids in reducing the look of dark circles beneath the eyes and increases collagen formation. The rose quartz roller and gua sha relieve tension when used on lubricated skin. The smooth crystal in Rose Quartz Gua Sha releases tension and also soothes the skin to allow product penetration.
