No7 Protect & Perfect Serum from Influenster

I received the No7 Protect & Perfect Serum complimentary through Influesnter for testing purposes.  What are my thoughts about it?  I don't really know!  The sample they gave was tiny!  I get it, you want to get people interested so that they will actually buy your product but when the sample is so small you can't try it more than once, you don't know if you really need to but it because you can't see an immediate result. 

This was NOT the size of the sample...just a stock photo I found.

So, will I buy it?  Eh, we'll see.  When I am out of my current product I may consider trying it out.
