Smooth skin is the perfect canvas for any makeup look. What a bummer it would be to have blemishes on your face during the party season! That’s why we included COSRX’s Clear Fit Master Patch in our Advent Calendar. COSRX’s best-selling hydrocolloid patches are available in the original multi-size version sealed in red packaging and a newer version in black packaging. The one sitting in today’s box is the newer version, which features patches in a single size that are just 0.12-0.14mm in thickness. The improved design is more waterproof and less visible, making it easier to apply makeup on top. The best way to use the patch, however, is to place one on top of your troubled spots and leave it overnight. The patch soaks up all the pus and shields off bacteria so the wounds can heal faster. Measuring at 10mm by 10mm, these patches are good enough for normal-sized pimples. Just make sure to apply them on clean, dry skin and store them in a cool, dry place.
