This product arrived quickly. I was drawn to its function to be able to absorb pus and oil from your skin. My skin is naturally oily, so I was really excited to find an acne patches that would work well with my skin. I was not disappointed at all! The patches actually work and was very gentle and effective overnight. I would highly recommend you add this to your skin care regiment.I use these on zits that are starting to form or on white heads. I feel like whenever I use them they speed up the duration of the zit. So by using them my zits go away a lot quicker. I only use them at night and they stay on until I am ready to take them off the next morning.
