using with a serum

I got this as a deluxe sample and have been using this with my day serum and night serum each from different brands – so I can try and see if I am getting results without using something similar too close together and I have to say I really love it so far I\’m not seeing huge differences in any lines but I can tell that over all my face does look dramatically better. I do believe I will buy the full jar once I run out.
