Numark Blister Plasters provide effective treatment of blisters and protection of areas prone to rubbing, such as the back of the heel, from blistering. Numark Blister Plasters are ideal to use at the first sign of rubbing to prevent blisters from forming or can be used on existing blisters to relieve pain and promote healing. The breathable, waterproof backing protects the blister from dirt and germs to help prevent infection, whilst the hydrocolloid pad creates ideal conditions to allow the skin to heal.
