Like the name, it is really an amazing serum. My skin doesn't like AHA or BHA. So far retinol has been a game changer for my skin texture, but this serum just makes my pores more calm and well maintained. Although I know you can not change the size of your pores, but within two weeks I can see my pores are much cleaner and smaller and hydrated. I've tried the toner after using the serum but didn't really find it is anything special with the toner. So it is the serum that impressed me. Really love it and have restocked plenty of it.
