Hydrocolloid Acne Patch

Hydrocolloid is a very hydrophilic colloid and is a common material in the field of wound care. Hydrocolloid is formed by heating and melting sodium carboxymethyl cellulose, medical viscose, elastomer and plasticizer, and the surface is compounded with polyurethane film. After the hydrocolloid is in contact with moisture, it can absorb moisture and form a gel. At the same time, the polyurethane film on the surface can allow oxygen and water vapor to pass through, but it has barrier properties to external dust and bacteria.
