useful acne stickers, well treated acne, 12 stickers of different sizes

This is an amazing product! It works really well over-night. 
 

It works best when you have big acne that's about to burst. If it doesn't seems to work for acne that's just pop on your skin. I bought 2 packs; 1 pack I have no complaint about but the other pack it doesn't seems to stick on skin as good as when I first use it. The other problem is that most of the times I notice it leaves sticky yucky when I try to take it off. I thought maybe because of face cream I applied too close to the patch; so the next time I don't apply cream around the patch but the next day it does the same thing leaving weird sticky texture. I haven't seen anyone having this kind of complaint before so I'm not sure what's going on.
