I did a lot of research before purchasing the High Frequency 4-In-1 Facial Therapy Wand and I couldn't be happier with my decision. I have noticed an improvement in the texture of my skin, diminishing of fine lines, reduced puffy eyes, fading of dark eye circles, new hair growth were my hair was thinning and receding and on and on. This Therapy Wand is a permanent part of my skin care regiment!
