This is innovation
I occasionally get pimples that seem like asteroids hit my face and landed. I used to have those "cutting" patches to cover up for these large pimples but this product really saves the time wasted for cutting a size perfect for your asteroid. The biggest size was just enough to cover a large pimple I had recently (I would say the pimple was like 8~9mm measuring the longest size) and it did fine pulling out the sebum. Of course it wouldn't fit and stay on as a customized cut patch, but it definitely has the adhesion to do the job. The huge pimple was gone in around 2 days.

Love then... They work like a charm...
I have sensitive skin. These works like a charm. Definitely recommend for anyone whose skin is acne prone. I also uses these to help cover small deep cuts that liquid bandages are not able to quickly treat.

Best brand
Out of all the acne patches I’ve used, this is by far the best brand. I’m really acne prone &’ as soon as I turned 22 my skin just decided it’s time to break out again lol. I went through everything to dermatologist, new products, &’ even tried other acne patches that would essentially just turn my pimples into scars. I vouch for this brand of your acne and scar prone.

Get the job done & adhere well
I ordered these by mistake once when trying to order more of the normal sized and mini ones from this brand. I love their other patches and thought these would be great to have on hand too. Sometimes I feel like these don’t seem as effective as the typical 12mm patches from most brands regardless of the type of blemish I put it on. But I think they get the job done. They definitely stay on, but I prefer patches with the visible circle in the middle and transparent edges. These are nearly invisible and smooth though so easy to cover with makeup if needed.
