Steri-strips work best when applied to clean, dry skin with the wound edges pressed firmly together before each strip is placed. The technique matters more than most people expect: proper spacing, skin preparation, and tension all determine whether the strips hold the wound closed long enough to heal. Here’s how to do it right.
When Steri-Strips Are the Right Choice
Steri-strips are designed for minor cuts and lacerations where the skin edges can be brought together easily without much tension. They work well on shallow, straight wounds that aren’t bleeding heavily. If you can pinch the wound edges together with your fingers and they stay close, steri-strips can likely hold them.
They’re not the right choice for deep wounds, jagged lacerations, wounds on joints or areas that move a lot, or cuts that are actively bleeding through direct pressure. Wounds on oily skin (like the scalp or face around the nose) can also be tricky because the adhesive won’t grip well. If a wound is gaping open, has visible fat or muscle tissue, or won’t stop bleeding after 10 minutes of firm pressure, it needs professional closure with sutures or staples.
Prepare the Skin First
This step makes or breaks the application. Steri-strips rely entirely on adhesive contact with your skin, so anything between the strip and your skin (blood, moisture, oil, lotion) will cause them to peel off prematurely.
Start by gently cleaning the wound and surrounding skin with mild soap and water. Pat the area completely dry with a clean towel or gauze. Don’t apply antibiotic ointment or petroleum jelly under or around the strips, as these will prevent the adhesive from bonding. If the wound is still oozing blood, hold firm pressure with clean gauze for several more minutes before attempting to apply the strips. The skin needs to be dry.
Some steri-strip kits include a skin adhesive (a liquid you paint on before applying strips). If yours has one, apply a thin layer to the skin on both sides of the wound, staying about half an inch from the wound edge, and let it dry until it feels tacky. This significantly improves how long the strips stay in place.
Step-by-Step Application
Peel one strip from the backing card. Hold it by one end, leaving the adhesive side facing down. Place one half of the strip on the skin on one side of the wound, pressing it down firmly. Then, using the fingers of your other hand, push the wound edges together so they meet evenly. While holding the edges together, pull the free end of the strip across the wound and press it down firmly on the other side.
The goal is to bring the wound edges up slightly so they meet, not to pull them flat. Think of pressing the edges together and slightly upward rather than just pulling the skin sideways. This gives the wound the best chance of healing with minimal scarring.
Place the next strip about 3 mm (roughly an eighth of an inch) away from the first, repeating the same technique. Continue placing strips along the entire length of the wound with consistent spacing. For most small cuts, three to five strips will cover the wound.
Add Reinforcement Strips
Once all your perpendicular strips are in place, you can add one or two strips running parallel to the wound, placed about half an inch (12 mm) from each end of your closure strips. These reinforcement strips sit across the ends of the perpendicular strips and reduce the peeling force on them, helping everything stay anchored longer. This step is optional for very small wounds but worthwhile for anything longer than an inch or on skin that moves.
Caring for Steri-Strips After Application
You can shower with steri-strips in place. When you do, clean the area gently with mild soap and water, then pat dry with a clean towel. Don’t rub, tug, or pull at the strips. Avoid soaking them in a bath, pool, or hot tub, as prolonged water exposure loosens the adhesive.
Don’t apply ointments, creams, or lotions over the strips. If the edges start to curl up, you can trim the loose edges with clean scissors, but don’t peel the strip off and try to reapply it. If a strip falls off early and the wound still looks closed and is healing well, you can apply a new one. If the wound reopens, it may need professional evaluation.
How Long to Leave Them On
Steri-strips typically stay on for up to two weeks. In many cases they’ll start to loosen and fall off on their own as the skin underneath heals and naturally sheds. Let this happen rather than picking at them.
After two weeks, if the strips are still firmly attached, you can remove them yourself. Peel each strip back slowly and carefully from one end, pulling parallel to the skin (not straight up) to avoid reopening the wound. If a strip feels stuck, dampening it with a wet cloth for a few minutes can help loosen the adhesive.
Signs of a Problem
Check the wound daily by looking at the skin around the strips. Some redness right at the wound edge is normal in the first few days. What isn’t normal: redness that spreads beyond the wound edges, increasing pain or tenderness when you touch the area, warmth or heat at the wound site, thick or cloudy discharge (white, cream, or yellow), or a noticeable odor coming from the wound. A fever above 101°F (38.4°C) alongside any of these signs points to infection.
Also watch for the wound edges separating. If the cut reopens or gaps wider than it was when you applied the strips, the closure has failed and the wound may need sutures, especially if it’s been less than a week since the injury.
