Good amounts of each product to help me decide if I wanted to purchase full size. I ended up purchasing full size of all but the eye contour cream as I had a bit of a sensitivity to it.
The other products transformed my skin in an amazing way and helped keep my skin barrier resilient while using prescription actives.
All the sample containers were easy to use though I decided to decant the serum ampoules into an empty dropper bottle for ease of application and longevity of use. I have been using the samples for almost 2 weeks daily (besides the Recovery Night Complex, which I use every few days), and there is still a good amount left in each except the serum, which lasted me 2 weeks of sparing daily use over my whole face (would have lasted longer had I been spot-treating but I wanted to see the global possible effects in making my decision to purchase the full size serums or not).
Some of the sample products will likely last 2-3 months as a small amount really goes a long way.
