Wow, Maxter--you said it all. I'm a huge fan also and because I buy regularly, I get lots and lots of samples. I've converted my sister and niece to the brand, so it works for older skin and younger skin, too.
It's horrendously expensive, but the Time Response Serum is unbelievable. Unlike Maxter, I am not blessed with good skin, yet this product (used after cleansing, and before moisturizing) has eliminated most wrinkles, evened the tone and texture of my skin and makes it look younger and smoother. People have noticed , including my husband! It lasts a long time, so I justify the cost.
Ask for samples so you can see how you like any of their products before buying anything full size.
