This product uses medical-grade hydrocolloid dressing as the core material. Based on the moist healing principle, it efficiently absorbs pus, oil and secretions inside acne, and forms an airtight protective film on the surface to block secondary infection from hand contact, dust and bacteria, accelerating acne drying and healing while reducing acne marks. With thinned edge design, it fits well and is not easy to curl, with waterproof and sweat-resistant performance that stays on during face washing and bathing. Each box contains two common sizes (8mm and 12mm) to fit acne of different sizes. It is drug-free, gentle and low-irritation, suitable for all skin types. Obvious absorption effect can be seen after 6-8 hours of overnight application, making it a basic essential for daily acne care.
