Personally, I like the wand because I can apply deep muscle stimulating pressure, but if I try that with the gua sha hurts too much. However, they're both good for your face in different ways. A good quality gua sha offers heating, vibrating, microcurrent, red-light therapy. Where the wand helps provides more benefits in terms of muscle simulation and lymphatic drainage.  Read more about a 4-way gua sha device and benefits.
