Our white quartz gua sha is best used with a body oil. Used for thousands of years in traditional chinese medicine, the gua sha boosts the lymph system and blood circulation as you rub it over the skin. The different sides of the gua sha help to smooth, firm and relax the tissues and alleviate heavy leg syndrome. The crenellated edge helps to break up fat deposits that can cause cellulite and give the skin its orange peel texture.
