Detailed answer

To prevent blackheads when wearing a face mask, it is important to maintain clean and moisturized skin. Cleanse your face twice a day with a gentle cleanser to remove dirt, oil, and bacteria. Exfoliating once or twice a week can help remove dead skin cells and prevent clogged pores. Additionally, moisturize your skin daily to keep it hydrated and prevent excess oil production. Avoid wearing heavy makeup under the mask, as it can clog pores and contribute to blackhead formation. Finally, consider using non-comedogenic or oil-free products to minimize the risk of blackheads while wearing a mask.
