Compeed Blister is a highly advanced, instant treatment for blisters. It acts like a second layer of skin to help prevent new blisters forming while soothing & healing those that already exist. Compeed Blister repels water, dirt & bacteria & can stay firmly in place for up to 3 days. The Hydrocolloid particles in Compeed Blister absorb wound fluid, creating a gel that protects the wound by sealing in moisture & preventing scab formation. This creates the optimal wound healing environment, speeding up the healing process.
