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.
Liquid bandages compared
| Product | Active ingredient | Label use |

Details are from each product's Drug Facts label on DailyMed. The antiseptic versions are flammable, so keep them away from fire or flame.
How to apply a liquid bandage
- Clean first. Every label says to clean the affected area. Mayo Clinic advises rinsing a cut under running water and washing around it with soap.
- Apply a small amount 1 to 3 times daily, and let it dry.
- Add a second coat for extra protection if you like, the labels say.
- Spray version: shake well first. New-Skin notes a thin film can form over the spray hole; scratch across it with a fingernail if the valve stops spraying.
- Expect a sting. The labels say it may temporarily sting when applied.
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
- Serious wounds: ask a doctor first for deep or puncture wounds, deep cuts, animal bites, serious bleeding or serious burns.
- Infected or draining wounds: New-Skin says do not use on infected areas or wounds that are draining.
- Stitches and mucous membranes: do not use over sutures or on mucous membranes.
- Diabetes or poor circulation: New-Skin says ask a doctor first.
- Eyes and large areas: do not use in the eyes or over large areas of the body.
- Raw or blistered skin: Bactine says not over raw surfaces or blistered areas.
- Children under 2: ask a doctor first, as the Bactine and Leader labels say.
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.
