The Pimple patch forms a barrier on the skin's surface, isolating pimples from the outside world. This reduces the risk of infection by pollutants like dust and bacteria, while also protecting against irritation from daily friction, preventing the spread of inflammation. The hydrophilic material absorbs exudates from acne, such as tissue fluid and pus, keeping the area dry and promoting healing. The enclosed environment it creates raises the skin's local temperature, accelerates blood circulation, and promotes cellular metabolism, helping to reduce acne inflammation and repair damaged skin tissue.
