I have some hormonal acne which is usually bumpiness and redness, combined with some acne nodules, and I wanted to find a product that calmed down the acne and reduce it's redness. I put a patch on one of my nodules and although I didn't really see a difference, it did go down a bit. Around my nodules I did have some bumps (not whiteheads), and lo and behold when I peeled the patch, the patch sucked these bumps and my skin around the nodule was smooth. I looked at the patch and you can see how it absorbed what the little bumps I had! I imagine this would work great for people who get whiteheads, but if you're looking to calm those nodules, I suggest finding something else.
