Review: Kosé Bioré Pore Cleansing Nose Strips Pack

Hello! ~♥ This is a review of the Kosé Bioré Pore Cleansing Nose Strips Pack. I bought these in Japan, but I have seen some versions with English text on them online, so they might be available in other countries too. A box of these includes 10 sheets with one nose stripe that is supposed to remove blackheads and cleans clogged pores.What Bioré says about this product:

Feature
·   Instantly pulls away oil and dirt build-up from your nose in just one use.
·   Biore strips are twice as effective as the other strips on the market at ridding pores of build-up and blackheads.
·   Formulated with a patented system to literally pull out dirt, oil and blackheads instantly.
·   Custom fit to reach dirt and oil in those hard to reach areas.
·   Helps reduce the appearance of pores.
·   Do not use more often than once every three days.
·   Dermatologically tested & hypo-allergenic.
Application Directions:
·   For external use only.
·   Remove strip from pouch.
·   Twist strip to loosen and separate slits prior to use.
·   After washing your face, thoroughly wet your nose. The strip won't stick on a dry nose.
·   Dry hands. Peel strip off plastic liner.
·   Apply to skin, smooth sides down, pressing down to ensure good contact with skin.
·   Let dry for about 10-15 minutes until stiff to the touch.
·   Slowly and carefully peel off starting at edges, pulling toward centre.
Active Ingredient:
·   Polyquaternium-37 & Silica

There is even a whole instruction with pictures inside the box! Make sit all sound so complicated, when it is basically just "wet nose, put stripe on nose, let dry, tear off".The stripes are black and the surface feels like cotton. Once they start drying on your nose they turn stiff, so you can guess when it is time to remove them even without watching the time.
I have tried quite a few of these nose stripes, usually with quite disappointing result. I only bought the Bioré ones because I have heard a lot of good about them. I wasn'ts ure which one to get though, since I just remembered "Bioré" and there are like 10 different kinds of these available in Japan. O_OSo, how did these work for me? Surprisingly, most of the time, they tear off an army of whiteheads / blackheads from the folds of my nose between nose and cheek. But that's usually  the only place where they remove them! I do not know why, I have blackheads and whiteheads all over my nose but all the others usually stay unimpressed by the nose stripes. Only after using this a couple of times I suddenly had a "100% success rate" and the stripe was full of blackheads and whiteheads everywhere. It was quite impressive and the only time I was actually tempted to take a photo (but then decided against it, because in the end it is still gross).I never figured out why it worked so well for me this one time, because I used the stripes exactly the same way as always. 
Quite unsure about this product as it partly works perfectly and partly not at all, but it is still better than the stripes which I tried before that never worked anywhere at all.
