I have been using this serum for over 2 weeks now. It's non-greasy (I have combo skin type), fast absorbing and non-irritating leaving a natural scent. I have using a few Noesa products at the moment. So far I find my pores less visible and the overal hydration level and firmness improved. Though I got some breakouts (sales said it's normal detoxing effect). Will see if more improvements can be seen after using the whole bottle up.
