To use an acne patch, first cleanse and dry the affected area. Peel the patch from its backing and gently apply it to the blemish, ensuring good adhesion. Leave the patch on for the recommended duration, usually overnight. The patch absorbs impurities, promotes healing, and prevents further infection. Replace the patch as needed. Avoid applying skincare products on top of the patch to maximize its effectiveness. It's a convenient and discreet way to address acne while protecting the blemish from external factors.
