Steri strips are a simple yet highly effective wound care tool, often used as an alternative or complement to stitches. Whether applied post-surgery by healthcare professionals or used at home to treat minor cuts, steri strips offer a sterile, non-invasive method for closing wounds and promoting natural healing.
This comprehensive guide will cover everything you need to know about steri strips—what they are, when and how to use them, aftercare tips, signs of infection to look out for, and when to seek medical attention.
What Are Steri Strips?
Steri strips, also known as adhesive skin closures or butterfly stitches, are narrow adhesive bandages designed to close small, shallow wounds.
They are commonly used by surgeons post-surgery or following the removal of sutures. In non-clinical settings, they’re available over the counter in most UK pharmacies such as Boots or Lloyds Pharmacy, and are ideal for self-care of superficial injuries.
They are generally made of porous, non-woven material with a hypoallergenic adhesive, making them safe for most skin types.
The structure allows the skin to breathe while gently keeping the wound edges together, promoting a natural healing process with minimal scarring.

When Are Steri Strips Used?
Steri strips are not suitable for every type of wound. Their ideal use cases include:
- Shallow cuts with clean, straight edges
- Minor surgical incisions
- Wounds less than 1.5 cm (½ inch) long
- Areas where skin movement is minimal (e.g., forearms or back)
They are not suitable for:
- Deep wounds or punctures
- Areas with heavy bleeding
- Highly mobile joints (e.g., knees, elbows)
- Wounds with ragged or uneven edges
If the wound is caused by a dirty or rusty object or continues to bleed after 10 minutes of pressure, professional medical care should be sought.

How to Apply Steri Strips: Step-by-Step Guide
If you cannot reach a healthcare professional and are confident the wound qualifies for self-treatment, follow these precise steps to apply steri strips correctly:
Step 1: Wash Your Hands
Before touching the wound or steri strips, wash your hands thoroughly with warm water and unscented soap to avoid introducing bacteria.
Step 2: Clean the Wound
Use cool, clean water and a mild, unscented soap to gently wash the wound. Pat the area dry with a sterile, lint-free cloth. Avoid rubbing as it could cause further irritation.
Step 3: Align the Wound Edges
Gently press the edges of the wound together using your fingers. Be careful not to apply too much pressure or cause pain.
Step 4: Apply the Steri Strips
Place one end of the steri strip on one side of the wound, then gently pull it across and secure it on the opposite side, ensuring the wound edges are pulled together. Do not place the strip parallel to the wound—apply it perpendicular instead.
Space each strip about 3mm (1/8 inch) apart. Apply as many as needed to fully cover the wound.
Step 5: Secure the Area
Optionally, apply a breathable, sterile adhesive bandage over the steri strips to secure the edges and protect the wound.
Aftercare: Do’s and Don’ts
Proper aftercare is crucial for ensuring that steri strips aid in healing effectively and do not lead to complications.
✅ Do:
- Keep the wound clean and dry for the first 24–48 hours.
- Trim any loose edges of the strip using sterile scissors.
- Inspect the wound daily for signs of infection.
- Allow steri strips to fall off naturally (usually within 5–10 days).
❌ Don’t:
- Don’t soak or submerge the wound in water for long periods (e.g., baths, swimming).
- Don’t peel or tug on steri strips, even if they begin to lift at the ends.
- Don’t apply any lotion, ointment, or cream over or near the wound without medical advice.
How to Remove Steri Strips Safely
In many cases, steri strips will naturally begin to peel off after several days. If you must remove them (typically after a week), follow these safe removal steps:
- Prepare a 50/50 solution of hydrogen peroxide and water.
- Soak a clean cloth in the solution and dab gently around the edges of each strip to loosen the adhesive.
- Peel slowly and gently from one side to the other. If you feel resistance, reapply the solution and wait a few more minutes.
Never remove a steri strip if the wound appears open or moist. Always ensure full healing before removal.
Signs of Infection: When to Seek Medical Attention
Although steri strips are generally safe, improper application or insufficient hygiene can lead to infection. Watch out for the following signs:
- Persistent or worsening pain or tenderness
- Redness spreading from the wound
- Discharge of yellow or green pus
- Unusual odour
- Fever or chills
Seek immediate medical care if:
- The wound won’t stop bleeding after 10 minutes of pressure
- You notice swelling, excessive redness, or heat around the wound
- The wound was caused by a rusty or dirty object
