Apply an Invisible Spot Cover to your blemish and let the hydrocolloid absorb pus and oil while protecting your skin against dirt so it can heal and flatten. Because your face doesn't have a "Delete" button for acne, patching is easier, faster, and more effective at healing pimples than popping them (which FYI actually spreads acne bacteria to nearby pores or deeper into your skin, basically inviting more pimples and future scarring).
