In my opinion this is such a wonderful product that I fall in love with for the first use. I am impressed about how well the pads work on my nose pore. As I notice for the first time I use it, after I apply the second pad, my nose feel tingling a little. I guess that’s mean it’s working ^.^ !! but as far I know, my nose don’t have any irritation while using this product and after using it. Great things are these pad and the essence smell wonderful. I usually don’t like the chemical smell for pore care products. Overall I give this product 5 stars !!!
