I liked the way it made my skin feel but not sure if it is worth the money. It was hard to tell with such a small sample size if it worked or not.

Sample too small
Sampled

I think this could be a great product, yet the sample was too small to really see any changes.

keep using it

I've used this product for about a year, and while I didn't see any changes immediately, I definitely saw changes over time.

I like the product. It makes my skin feel soft. The sample size may not have been enough to notice an improvement in fine lines, wrinkles, and elasticity. I didnt see enough of a change where I have been motivated to purchase it and ditch my normal routine.

This product didn't seem to do anything. Maybe it would have, but the sample size was so small it was hard to tell if there would have been some kind of benefit if I had used it longer. On the plus side, it did not irritate my skin. I tried it on a forehead wrinkle and saaw no improvement.

I liked it but have another vitamin c product that I love... hard to compare a little sample to something I use and already love.

This seemed nice but the sample was really too small to get a good idea.

I dont think this was a big enough sample to get a good feel on how it works for my skin.

Just okay
Sampled

The sample was too small to produce noticable changes. I didn't have any problems with the product, but it is more expensive than my usual serum. Too big of an investment without seeing any benefit.
