Stainless Steel Gua ShaStep up your skin care routine with this versatile and antibacterial tool. Crafted from 100% medical grade stainless steel, this gua sha not only stimulates circulation but also supports lymphatic drainage, and relieves muscle tension. Use with an oil. We recommend our Super Ego face oil to prevent tugging, but anything with a slip will do. Be gentle. Though redness is normal when using this tool, pressing too hard on your skin may cause bruising.
