I tried it a couple of times with and without the Pore Beauty Silky Essence and found that this step made a big difference in the results. With it, my nose remained matte but without it, my nose started turning into a lightbulb – oily, greasy and shiny – really quickly. Therefore, I recommend using all of the products in this Pore Beauty Nose Pack to obtain the maximum efficiency. After the first mask, I did notice whiteheads protruding out of my pores, which I could easily rub or wipe off with a cotton bud. The mask for the second step contains alcohol but since my nose isn’t sensitive to it, I had no problems with it. Overall, the experience was completely painless and the masks were easily taken off, as they didn’t stick to my skin, unlike pore strips.
