Wow! This is an amazing product! I am 30+ caucasian with dehydrated skin that is prone to congestion and I always struggle with serums because they usually made my pores clog even more. Not this one! Even though the consistency is somehow sticky, it doesn't set into pores and clog them if that make sense. Also I can see the results on my skin just after a few days of using it. My skin is definitely brighter and smoother. I use it together with TIAM My Signature A+ Cream so I don't know if the results would be as visible if you use it alone but this combination works extremely well for me and I highly recommend it and will definitely repurchase both of them! Also it doesn't burn. It tingles a bit especially within a few first applications but it's getting better with every use. Definitely my new favorite!
