AluSpray Aerosol Bandage Aids in protecting wounds against bacterial contamination. It works by allowing the wound to oxygenate (breathe) to aid in healing. It can be applied without disturbing sensitive wound tissue, or may also be applied over ointments used to aid in wound healing. AluSpray Aerosol Bandage contains a proprietary carrier that aids the active wound protective formula to adhere to the skin and cannot be washed off. It can be washed off with soapy water to inspect the wound. Use every three days to insure that an optimal bacterial barrier is maintained.
