Quick answerA liquid bandage is a liquid you brush or spray onto a minor cut or scrape; it dries into a thin covering. The FDA defines it as a sterile liquid or semiliquid used to cover an opening in the skin. New-Skin adds benzethonium chloride 0.2% as a first aid antiseptic, and Bactine MAX Bandage adds lidocaine 4% for pain. Clean the area, apply a small amount 1 to 3 times daily and let it dry. Expect a brief sting. Do not use on deep cuts, animal bites, infected or draining wounds, or over stitches.

What a liquid bandage is

FDA regulations describe a liquid bandage as a sterile device that is a liquid, semiliquid, or powder and liquid combination used to cover an opening in the skin or as a dressing for burns, and also as a topical skin protectant.

Many store products also contain a drug, so they carry a Drug Facts label. New-Skin lists nitrocellulose, amyl acetate, butyl acetate, ethyl acetate and camphor among its inactive ingredients, and the label says to let each coat dry.

How to apply a liquid bandage

How to remove it

New-Skin and Leader both say to remove the film by applying more liquid bandage and quickly wiping it off. New-Skin also warns it will stain floors, countertops and other finished surfaces, so apply it over a sink or towel. Cap the bottle tightly, store it at room temperature away from heat, and do not store the spray above 120°F; the spray is under pressure, so do not puncture or burn the can.

When not to use a liquid bandage

The labels also warn that deliberately concentrating and inhaling the contents can be harmful or fatal; keep them away from children.

Liquid or regular bandage, and when to see a doctor

Liquid and strip bandages both cover minor cuts; which you use is mostly about the spot and your preference. For other minor wounds, see our adhesive bandages guide and hydrocolloid bandages guide. The labels say not to combine it with other first aid products such as lotions and creams, so skip antibiotic ointment under it.

Stop and ask a doctor if the condition persists or gets worse, or if infection occurs. Mayo Clinic lists infection signs such as expanding color change, increasing pain, drainage, warmth or swelling, and says a tetanus shot is needed if it has been more than five years and the wound is deep or dirty.
