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 and healing those that already exist. Compeed Blister repels water, dirt and bacteria and 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 and preventing scab formation. This creates the optimal wound healing environment, speeding up the healing process.
