I am a 64 year old male. After one week of daily use I, my wife, and even one of my female co workers have noticed significant changes. My co-worker asked, “What are you using? Some kind of special Korean skin care products?” Which I laughed, “As a matter of fact, Yes I am!” The lines in the corners of my eyes have disappeared and my face overall has much more smoothness and elasticity. I am going to keep with the regiment!
