6–12 hours
The duration of use depends on the condition of the pimple and the type of patch; generally, a single application for 6–12 hours is recommended, though patches should be replaced promptly if the pimple has ruptured.
Pimple patches primarily work by absorbing secretions, blocking out bacteria, and accelerating the healing process. For closed comedones or inflamed, red pimples that have not yet ruptured, the patch helps reduce inflammation and is best used overnight for 6–8 hours. If the pimple has ruptured (exuding pus or fluid), the patch should be replaced every 4–6 hours to prevent the accumulation of secretions from compromising effectiveness.
