I just ordered this serum last week, it came today and I used it about 3 hours ago. Only one use and I really cant believe the difference already. I was nervous to buy it from a vitamin store! Its so much cheaper than other serums. I figured u get what u pay for. But I was wrong. My fine lines around my mouth from smoking are already fading. Maybe its an eye trick, I dont know. But I swear my skin looks plumper, shinier, softer and younger. Already!! I cant wait til 30 days have passed. Dont forget to use this when your face is damp and use a really good moisturizer over top so it doesnt dry your skin. It locks in moisture when u use it right. If u use it wrong it'll dry u out. But I am already loving this stuff!!!!
