Treating self-harm wounds follows the same principles as treating any cut, bruise, or burn: clean the area, protect it from infection, and give it the conditions it needs to heal. The specific steps depend on the type and depth of the wound. Below is a practical guide to caring for these injuries at home, recognizing when professional medical attention is needed, and supporting long-term healing of the skin.
Caring for Cuts and Scrapes
Start by washing your hands with soap and water. If the wound is bleeding, press a clean cloth or bandage gently against it and raise the area until the bleeding slows or stops. Most shallow cuts stop bleeding on their own within a few minutes.
Once bleeding has stopped, hold the wound under cool running water to rinse away dirt and debris. Wash the skin around the wound with soap, but keep soap out of the wound itself. Don’t use hydrogen peroxide or iodine, both of which can irritate healing tissue and actually slow recovery. If there’s debris you can’t rinse away, use tweezers cleaned with rubbing alcohol to carefully remove it.
After cleaning, apply a thin layer of antibiotic ointment (like the kind sold for first aid at any pharmacy) and cover the wound with a non-stick bandage pad. Non-stick pads, sometimes called telfa pads, won’t pull at the wound when you change the dressing. Change the bandage at least once a day or whenever it gets wet or dirty. Keeping wounds covered and slightly moist with ointment promotes faster healing and reduces scarring compared to letting them dry out in open air.
When a Cut Needs Medical Attention
Some wounds are beyond what you can safely manage at home. You should seek medical care if:
- The bleeding won’t stop after 10 to 15 minutes of firm, steady pressure.
- The wound is deep or gaping. If you can see fat (yellowish tissue) or muscle beneath the skin, or the edges of the wound don’t come together on their own, it likely needs stitches or adhesive closure strips.
- There’s numbness or limited movement near the wound, which could signal nerve or tendon damage.
- The wound is on your face, hands, or over a joint, where proper closure matters for function and appearance.
If your last tetanus shot was more than five years ago and the wound was made with anything that could carry dirt or bacteria, the CDC recommends getting a tetanus booster. This applies to puncture wounds and any wound contaminated with soil or debris.
Caring for Burns
For a superficial burn (red, painful, no blisters), hold the area under cool running water for at least 10 minutes. Don’t use ice directly on a burn, as this can damage already-injured skin. Once cooled, apply a lotion containing aloe vera or cocoa butter to prevent the skin from drying out, then cover loosely with a clean bandage. The loose wrapping keeps air off the area and reduces pain.
If blisters form, the burn has reached the second layer of skin. Don’t pop or break the blisters. They act as a natural barrier against infection. If a blister breaks on its own, gently wash the area with water and mild soap, apply antibiotic ointment, and cover it. Burns larger than about three inches across, burns on the face, hands, feet, or genitals, or any burn that looks white or charred needs professional treatment.
Caring for Bruises
For bruises or blunt-force injuries, the standard approach is rest, ice, compression, and elevation. Apply a cold pack wrapped in a thin cloth (never directly on bare skin) for 10 to 20 minutes at a time during the first eight hours. This helps control pain and limits swelling.
If the area is swollen, wrapping it gently with an elastic bandage can help, but don’t wrap so tightly that you feel numbness or tingling. Elevating the bruised area above your heart when resting encourages fluid drainage and reduces swelling. Most bruises resolve within two weeks. A bruise that’s expanding rapidly, feels extremely hard, or limits your ability to move the area warrants a medical visit.
Recognizing Signs of Infection
Check your wounds daily when changing bandages. Normal healing involves some initial redness and mild tenderness, but infection looks different. Watch for redness that spreads outward from the wound, increasing warmth around the area, swelling that gets worse rather than better, pus or cloudy discharge, and increasing pain after the first day or two. A fever developing alongside any of these signs is a clear signal to get medical care promptly. Skin infections caught early are straightforward to treat, but they can become serious if ignored.
Reducing Scars Over Time
Once a wound has fully closed and any scabs have fallen off naturally, you can start working on minimizing the scar. Silicone-based products are considered the gold standard for scar management. Both silicone gel sheets (adhesive strips you place over the scar) and topical silicone gel (which you apply like a lotion) are equally effective. A systematic review of clinical trials found that silicone gel significantly reduced scar height, pigmentation, and stiffness compared to no treatment.
The key is consistency and patience. Apply the silicone product daily for at least two months. Results typically become noticeable after six months of use, though the treatment period in studies ranged from one to six months. You won’t see meaningful improvement at the three-month mark in most cases, so don’t give up early. These products are available over the counter at most pharmacies.
Sun protection also matters. New scars darken faster than surrounding skin when exposed to UV light, so covering the area or applying sunscreen with SPF 30 or higher helps prevent permanent discoloration.
Building a Simple Wound Care Kit
Having supplies on hand means you can take care of a wound immediately rather than leaving it uncovered. A basic kit should include:
- Non-stick wound pads in a few sizes
- Medical tape or self-adhesive bandage wrap to hold pads in place
- Antibiotic ointment for shallow wounds
- Sterile saline or access to clean running water for rinsing
- Tweezers cleaned with rubbing alcohol
- An elastic bandage for compression on bruised areas
- A reusable cold pack
Hydrogel pads are worth adding if burns are a concern. They’re soothing, reduce pain on contact, and keep the wound moist.
Getting Support Beyond Wound Care
Self-harm significantly increases the risk of future serious injury, and that risk is higher for people with a history of repeated self-harm. A mental health evaluation can help identify what’s driving the behavior and open the door to treatment that addresses the root causes. If you’re in crisis, the 988 Suicide and Crisis Lifeline (call or text 988) connects you to trained counselors 24 hours a day. The Crisis Text Line (text HOME to 741741) is another option if you’d rather not talk on the phone.
If you go to an emergency department for wound care, you may be offered a mental health assessment before discharge. This isn’t punitive. It’s a standard recommendation because connecting people with support at that moment can make a real difference in long-term safety.
