Amazing When Used CORRECTLY
These do a VERY good job at absorbing oil. They are not wet. They are silky blue sheets that grab oil with each dab. The knockoff versions (CVS brand), are white and matte like paper, and do not absorb as well. This matte material produces more drag, and can irritate the skin.
These are useful when used correctly, meaning not over-used. If you cleanse your face twice daily, you should not use these more than once per day. Constant oil loss results in an increased oil production, leading to acne. These are great for removing that oil in the middle of the day in between washes.
PS: These are not good at absorbing liquid. So, if you have sweat on your face, dab the sweat with a towel or tissue first.
