I used this once on a blemish in my t zone and once on a blemish near my hair line before going to bed. I didn\’t notice any difference on the blemish in my tzone, but I did notice my blemish near my hairline was significantly smaller when I woke up since I don\’t get oily there. It\’s also a little pricey considering you only get 20 stickers and your paying a little over 20$ for it. I usually get 2-4 zits at a time so I will use this mainly for traveling or else I would go through the entire box within a week.
