COSRX AC Collection Acne Patch is a specialized hydrocolloid patch designed for intensive acne treatment. The package contains 26 patches in two sizes - small (9x13mm) and medium (11x16mm) oval-shaped patches that provide targeted care for different sizes of blemishes. The patches come in a hygienic resealable package and feature an oval shape design that provides better coverage and adherence to the skin. The hydrocolloid material helps absorb excess fluid while creating a protective barrier over the affected area. Being a personal hygiene product, detailed ingredients and features are intentionally omitted.
