Honestly, I don't know what to say about this one. It is a good product, but it just isn't what I was looking for. When I would use the patches, pimples would indeed go away faster. Another thing I noticed, is that I wouldn't get any scaring if I used them.
Like I've said, it is a really good product, really helpful, it's just that I expected it to dry out pimples but it doesn't do that, it heals them, which is a good thing, but not what I personally was looking for.
Anyway, if you have sensitive skin, you can definetely use this, I have sensitive skin too and the patches didn't irritate my skin, so it's safe to use.
The picture is from the web, I used up all my patches prior to writting this review, so sorry for that!
