I bought this as a gift for my Mom as she is in her late 50' s and has been experiencing changes in her skin. Collagen being most important to her research as she has been taking active Collagen by Lorna, six capsules daily for close to five years now, she swears by it but still felt she needed something more to stimulate her elasticity. It has been close to three months with no results other than abnormal dryness and irritation, angry skin, redness, and strange breakouts around her chin and mouth area. She gave up and left the device to me to try. I'm in my early 30's and paid good money for it, so I too tried it. The first month I had to stop as it was drying out my skin. I think I have excellent skin and have never had to wear foundation. It took two weeks to correct my dryness and redness. I had to go as far as applying BB tint moisture foundation to my embarrassing patches. I'm not a fan and tried to sell it on Craigslist. Still no takers as it is very pricey. I guess I will have to take a hit if I want it sold.
Bottom Line: No, I would not recommend this to a friend
