Gua Sha—a facial massage tool that enhances beauty rituals by promoting the lifting and smoothing of the skin, leaving the face lifted and radiant after use.   Gua Sha has been practiced in Traditional Chinese Medicine for thousands of years. The Obsidian Gua Sha boosts blood flow and circulation to the skin and which improves skin tone, aids in healing and reduces puffiness and fine lines. The Black Obsidian used to make the Gua Sha tool is derived from molten lava glass and has a strong spiritual connection to the earth. Obsidian is seen as a grounding and protective stone. It naturally retains warmth and is great to use on congested, blemish prone skin.
