I never had acne as a teenager, but at 28, had 10 zits on my face at one time. A friend told me about the Galvanic Spa system from Nu Skin Enterprises. I rubbed this hand held device on my face for 10 minutes with the special gels, and the next morning my acne was dried up and the redness was gone! I was so amazed that I am now selling the units. The same little miracle machine also decreases lines & wrinkles and reduces cellulite! It's like a professional spa facial in the comfort of your home! Amazing technology!
