The Vitamin CE Caffeic 16+2 Serum is actually pretty thick and sort of sticky. I wasn’t in love at first. I was sort of panicked actually. I don’t typically accept things for review that I don’t think I will love. So, for testing sake I stuck it out and followed directions. I used it exactly as it says to. I applied little to almost none all over my face. It was pretty sticky but after I applied my moisturizer over it the stickiness would disappear. My face still felt like it had something on it though and applying actual makeup overtop became useless. I do need to note that I have a limited time to get ready in the morning. If I gave the product the time it needs to sink in I would definitely be ok for makeup application.
