This is really awesome product. bought 3 pcs of this on amazon.  It evens out my skin tone and heals the acne scar slowly. My face is super oily and my skin just doesn't' absorb moisture from most of the product and they are just sit on top of my skin causing clogs. But this serum absorb into my skin fast and leaves smooth surface not sticky. I really love it, I am going to continuously using it.
