oops!

I really liked this product but DO NOT spot treat for breakouts after application. I applied product at night before bed then spot treated (BP) 3 areas on my face for break outs (chin, and 1 spot on each cheek) and woke up with a mild trio of chemical burns. No pain or peeling, just red patches that faded after a couple days.

Less lines
Sampled

Not sure if it was in my head but I felt like this worked wonders the first time using, lines were less noticeable. Tried again later that night and did not notice a change. Weird.

Hmm, no difference

I am always up for a better skin care product and had high hopes that this would do as it promised. Nope. I followed the directions exactly and saw no difference. It felt sticky on and made my face feel even more dry.

Best vitamin C product I have used
Sampled

I have tried many vitamin C serums. I noticed right away that my skin looked smoother. As for the lines, only time will tell. I will be purchasing the full size.
