What customers say
Customers appreciate the extra-large size and high quality of these patches, which are effective for covering large areas like the forehead, cheeks, and chin. They are particularly beneficial for absorbing pus from pimples and reducing breakouts, especially around periods. Users find them easy to use, with good adhesion and no smell. The patches work well on sensitive skin and provide visible results after one use. However, some users report that they can be too sticky, causing pain and irritation upon removal, and may leave a sticky residue. The edges sometimes don't adhere fully during sleep, and wearing them overnight can wrinkle the skin. Despite being pricy, many customers find them worth the cost due to their effectiveness in removing gunk and improving skin texture. Overall, they are highly recommended by most users who plan to repurchase.

These patches are very large, I ended up cutting some in half as I didn't need that amount of coverage. If I had to choose I would choose the regular or intense over the the large.

I love Korean beauty products it is very useful and worth trying. These patches is amazing I had a hormonal acne on the sides of my face and most of it under the skin and blemishes. When I used Cosrx patches after a 24 hours all the acne came on the surface and after 3 days of using it all the pimples on my side cheeks are gone. It is really beneficial especially if you have a big area on your face that has breakouts. I really recommend it because it protects the pimples from inflammation when you wear makeup or while you’re sleeping.

Bought this cause i ve read it may help with skin health . Haven’t tried it yet but I’ll come back and update the review if the product really helped me. If not, I’ll just leave the rating at 3 stars and the review as it is - which doesn’t mean that the product was bad, just that it neither improved that aspect nor made things worse.

I haven't used it for a while after I purchased, but recently it's been very helpful in restoring my skin after a recent bacterial acne breakout. The shape and size work perfectly for the anatomy of the face. The quality is great and worked well for my sensitive inflamed skin. It's thick hydrocolloid with thin edges which help them stick nicely. They are comfortable to wear for extended periods or while you sleep.

I’m obsessed with these they’re perfect for if you get cystic acne or a large breakout somewhere on your body. I haven’t used it for face but I’m sure you’ll benefit from it - great large size and quality it really stays put where you need it to.
