I have been trying this product for a few weeks now, and my rating will probably be a double thumbs up.
The bottle is plastic, which can feel okay if you want to take it in a gym bag without risking it breaking. The downside of the packaging is that the ampoules are not transparent, which means you don't know how much is left.
I am positive about buying a new one to evaluate over a longer period since it doesn't get messy during application, softens my lines in the face, and as a 52-year-old, my skin actually feels a bit fresher in the face. It absorbs immediately and gives a mild glow (I don't mean glitter).
I have tried this product for free on behalf of Smartson, for an honest review.
