Detailed answer

To effectively treat a spot, it is generally recommended to leave the spot treatment on your skin for a minimum of 30 minutes. This allows the active ingredients to penetrate the blemish, targeting and reducing inflammation and bacteria. However, it's important to read and follow the specific instructions provided with your spot treatment product as some may require longer or shorter application times. If there are no specific instructions, you can leave the spot treatment on for even longer, such as overnight, provided it doesn't cause any skin irritation or dryness. Always ensure to cleanse your face thoroughly before and after applying the spot treatment to maximize its effectiveness.
