This transparent acne patch is a thin, clear sticker made from hydrocolloid material that is placed directly on pimples. It helps absorb pus and oil, protects the blemish from dirt and bacteria, and prevents touching or picking. Some patches are also infused with active ingredients like salicylic acid or tea tree oil to speed up healing. They are discreet, easy to wear under makeup, and ideal for reducing inflammation and promoting faster acne recovery.
