I have a lot of baby hair on my face and it tends to build up sebum and make my pore bigger. I also have very sensitive skin and lots of redness around my cheeks. I do see a noticeable different when using this serum. I don't really get any tingling sensation which is a plus because of my sensitiveness, mostly to fragrance or alcohol and some certain essential oils. Definitely no irritation. My skin texture has improved. I use this at night and the whitening essence in the morning. Love this combination. Really work well for my skin. LOVE LOVE LOVE 

At first, I didn't feel ant "prickling" but by the third use and forward I can definitely feel that sensation. I love this serum, I have oily skin and my skin is reacting to this very well. My skin always looks refreshed and nourished. 

I love this serum. Bought it along with the Fresh Herb Calendula Tincture toner and have been using it for the past 2 months. I use it every night and in the morning I wake up with soft hydrated skin. It's really helped my skin to become more hydrated and refined. Definitely give it a chance if you haven't tried it yet. Regarding the prickling feeling, I've never felt it, at most all I've felt was a slightly tingly feeling. I think it helps that I layer in hydration before the serum with FTE, toner and essences.
