My subject title above says it all. I have used 3 full bottles of this pore tightening essense and I can clearly see that the pore which used to be as big as a meteor crater is now 3x smaller than it used to be. However, if youre someone who's looking for an essense or serum that will miraculously make your pores disappear then I won't recommend this one just cause It didn't happen to me yet. Aside from that it's an overall great product!
