To enhance the effectiveness of our Korean acne patches, ensure you apply them to clean, dry skin for optimal adhesion and performance, as applying them to oily or moist skin can reduce their effectiveness and longevity; select the right size patch to fully cover the blemish, as improper coverage can limit the patch's ability to draw out impurities and create a protective barrier; for best results, keep the patch on for the recommended duration, as this ensures it remains effective in reducing whiteheads, blackheads, and pustules; avoid excessive touching or manipulation of the patch to maintain its waterproof and durable properties; and store the patches in a cool, dry place to prevent them from becoming compromised by moisture or contaminants, ensuring they stay effective and non-irritating for all skin types.
