The COSRX Acne Pimple Master Patches contain 24 hydrocolloid patches (10 small, 5 medium, 9 large). They absorb pus and fluid, protect against bacteria, and promote healing quietly, invisibly, and without residue. They're especially effective on fresh whiteheads and spontaneous pimples.

Application:
• Cleanse and dry skin
• Choose a larger patch than the pimple
• Apply with adhesive side
• Leave on for 6–12 hours (max. 24 hours)
• Apply before skincare routine, do not stick over it
