I was quite excited to try this sample. I am really interested in skincare and serums. Unfortunately this sample is barely enough for one try and not enough to make up your mind at all if you really like it or not. Obviously such a product is hard to evaluate in a sample. But even then, samples can show you if you are allergic to the product for instance. In this case, I can only say that consistency is nice and the concept is quite interesting. If you are interested make sure to ask for a couple of samples and not just one.
Would I buy this product based on the sample? No
