I had some doubts about this product's ability to draw impurities out of blemishes, so the main reason I bought it is to help stop external debris from entering my skin (I touch my face a lot; really bad habit). However, it really does work! I know popping pimples is bad, but this product helps pimples come to a head faster and with less redness, and easy to extract. It also helps the skin heal a little faster. The patches themselves are clear and non-shiny (helps hide the pimple). The stickiness doesn't leave any residue on the skin and is easy to apply and remove. It didn't cause any irritation for me and I have sensitive/combination skin. I'd definitely use this product again!
