Works well with others!
Size: 2.03 Fl Oz (Pack of 1)
Initially and by itself, I really didn’t see any changes to my face that made me confident with this product. But now that I have a skin routine, I think it works well! Now I like it and I see changes. But alone or with few products, I’m not sure how effective it is!

Decrease in black heads. Smoother skin!
Size: 1.01 Fl Oz (Pack of 1), Size: 1.01 Fl Oz (Pack of 1)
I’ve never used such a great pore minimizer for this reasonable of a price. I love how smooth and clean it makes my face feel. I’ve been using it twice a day after cleansing my skin. Noticeable difference in visible pores and decrease in black heads on my nose and chin. Highly recommend!! Come on with this price, you have nothing to lose.

Serum does not work to reduce pore size
Size: 1.01 Fl Oz (Pack of 1)
While this serum does somewhat smooth skin it does absolutely nothing to reduce pore size which is primarily genetic and is resistant to most products. Not worth the money.
