The best thing about the product is the thick consistency and that the skin feels very hydrated. The packaging itself is also very nice! I don't really think there's any difference in how well the makeup holds. I've tried doing my makeup and gone a whole day both with and without the serum, and there's no difference in how well the makeup stays on. However, I don't think any primer/serum usually helps my makeup stay better in place. I still have to say that the product is affordable if you're looking for more hydration throughout the day.
The review was conducted on behalf of Smartson - the test pilot was allowed to try the product for free.
