Acne Pimple Master Patch — Reddit Reviews
by COSRX
Updated September 3, 2026
Hydrocolloid patches absorb pus from pimples and reduce size overnight; adhesion varies.
What the community says
These hydrocolloid patches stick over whiteheads and cystic pimples to absorb gunk and flatten spots overnight. They work best on clean, dry skin and for acne that has surfaced. Adhesion issues and variable effectiveness on deep pimples make results hit or miss.
