I've been using Biore products for several years and these strips are a great help in cleaning out my pores! I don't wear makeup, but my skin tends to get very oily around my nose, chin, and forehead. The combo pack is great for treating all three areas.
The best way to use this product is to dry your face after a hot shower, so your skin is slightly damp, before applying the strips wherever your pores most need them. The product takes between ten and fifteen minutes to stiffen, and it does feel very strange while drying. It does not hurt if you remove them quickly and will pull out a lot of dirt from your pores.
It takes practice to find the right skin dampness so that the strips don't stick too well, leaving sticky goo on your skin, or stiffen without attaching to what's clogging your pores. I'm always amazed at how many little columns of stuff are on the strips I remove. It looks disgusting, but it's much healthier removed from my skin! These strips don't always remove large blockages well, especially not around the nose, but serve well for general cleansing on a weekly or daily basis. Afterwards, my face always feels fresh and clean. I use two facial strips for each nose strip, so I sometimes have to buy a box of just facial strips (they sell both kinds individually as well). I definitely recommend these strips to remove oil buildup from your skin!
