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). How to use: cleanse the affected area and let skin completely dry. Select patch that best fits size of blemish and apply to affected area. Lightly press down for 3 seconds to secure. Remove patch after a minimum of 4-8 hours when patch turns white to reveal flattened blemish. Best results when left on overnight.
