Pimple patches are small, adhesive stickers designed to treat acne. They are typically made from hydrocolloid material, which helps absorb excess oil and pus from pimples while creating a protective barrier. This can speed up the healing process and reduce the risk of picking or touching the blemish. These patches come in various sizes and can be worn overnight or throughout the day. They are easy to use and can be applied directly to clean, dry skin. Many people find them effective for reducing the appearance of acne and preventing further irritation.
