Kiehl's - sirsphere review for Powerful-Strength Vitamin C Serum

I really love this serum! As with any vitamin C serums, it has a little ‘funky’ smell to it, but just faint. It sometimes tingles on my skin when I use it. For me, I get the feeling of ‘it works’ when it tingles. My skin looks so much better just after a few weeks using it. I only use it in the morning. My complexity is a lot brighter and smoother and my skin is glowing. My crows feet around the eyes look better, smoother. I’m very satisfied and highly recommend!
