The initial pressure bandage placed by your surgeon stays on for about 24 to 48 hours. After that, you switch to a daily routine of cleaning the wound, applying a thin layer of ointment, and covering it with a fresh bandage. This daily bandaging continues until your sutures come out, which can be anywhere from five to 14 days depending on where on your body the surgery was performed and what kind of repair your surgeon did. If your wound was left to heal on its own without stitches, you may be bandaging for several weeks or even longer. The short answer, then, is that “wearing a bandage” after Mohs surgery is not a single stretch of time but two distinct phases with different purposes.
The First 24 to 48 Hours
Right after your Mohs procedure, the surgeon applies a pressure bandage over the surgical site. This first bandage is doing a specific job: compressing the wound to minimize bleeding and swelling. It is usually bulkier and tighter than anything you will apply yourself later. Most surgeons ask you to leave this bandage completely undisturbed for at least 24 hours, and some request 48 hours depending on the wound’s location and complexity.
During this window, resist the urge to peek. Lifting the bandage to check on things disrupts the clot forming underneath and can restart bleeding. If blood soaks through the outer layer, the standard advice is to press firmly with a clean cloth for 15 to 20 minutes rather than removing the whole dressing. Some clinics follow up with a phone call within the first day or two specifically to check on bleeding, swelling, and pain control before you transition to managing the wound yourself.
Daily Wound Care After the Pressure Bandage
Once that initial pressure dressing comes off, your active role begins. The typical routine is straightforward: gently clean the wound with mild soap or a dilute hydrogen peroxide solution (your surgeon’s instructions will specify), pat it dry, apply a thin layer of plain petroleum jelly or whatever ointment your clinic recommends, and cover it with a non-stick bandage or gauze secured with tape. You repeat this once or twice a day until the wound is either closed by sutures that have been removed or has healed enough that a bandage is no longer needed.
The ointment-and-bandage step is not optional or cosmetic. Decades of wound-healing research show that keeping a wound in a moist environment speeds up the regrowth of skin and reduces scarring compared to letting the wound dry out and scab over. At a cellular level, the inflammatory phase resolves faster and the cells responsible for building new tissue (fibroblasts and the cells that form new blood vessels) ramp up more quickly when a wound stays moist. In one comparison, moist wounds had shifted substantially toward this rebuilding phase by just five days after injury, while dry wounds lagged behind.1PubMed. Comparison of the effects of moist and dry conditions on dermal repair Moist, covered wounds also tend to produce less noticeable scars.2PubMed Central. Clinical Impact Upon Wound Healing and Inflammation in Moist, Wet, and Dry Environments
A common worry is that covering a wound traps bacteria and increases infection risk. Clinical reviews have actually found the opposite: occlusive dressings that seal in moisture generally achieve lower infection rates, even when some bacterial growth is present under the dressing.3PubMed. Moist wound healing with occlusive dressings. A clinical review. The bandage acts as a physical barrier against outside contamination while the moist environment underneath supports the body’s own defense mechanisms. So when you catch yourself thinking, “Maybe I should just let it air out,” that instinct is actually working against your healing.
How the Type of Repair Changes the Timeline
Mohs surgery removes skin cancer layer by layer, and what happens next depends on the size and location of the wound that remains. The type of closure your surgeon performs has a direct effect on how long you will be bandaging.
- Linear closure: The wound edges are stitched together in a straight line. This is the simplest repair, and bandaging typically continues until suture removal, which may be as early as five days for facial wounds or up to two weeks elsewhere on the body.
- Flap repair: Nearby skin is repositioned to cover the wound. Flaps involve more tension and often more suture lines, so the bandaging period and restrictions on activity tend to be a bit longer, and your surgeon may want to see you back sooner to make sure the flap’s blood supply is healthy.
- Skin graft: A piece of skin is taken from another area (often behind the ear, the collarbone region, or the inner arm) and placed over the wound. Grafts require a special dressing called a bolster, which is a padded compression bandage sutured or taped directly over the graft to hold it firmly against the wound bed so new blood vessels can grow into it. The bolster typically stays in place for about five to seven days and should not be disturbed during that time.4PubMed Central. Management of full-thickness skin grafts After bolster removal, you transition to regular daily wound care for another week or two. You will also have a second wound at the donor site that needs its own bandaging.
- Second intention healing: The wound is left open and allowed to heal from the bottom up on its own, without stitches. This is sometimes the best option for certain areas like the temple, forehead, or scalp, or for concave surfaces like the inner corner of the nose. Healing takes considerably longer, often several weeks to a few months, and you will be doing daily bandage changes the entire time. Consistent occlusive wound care is especially critical for these wounds.5PubMed. Secondary Intention Healing Over Exposed Bone on the Scalp, Forehead, and Temple Following Mohs Micrographic Surgery
If your surgeon did not explain which type of repair you received, ask. It makes a real difference not just to your bandaging timeline but to what activities you should avoid and when you should worry about how things look.
When Sutures Come Out and What Happens After
For wounds that were stitched closed, suture removal is the milestone that marks the end of the intensive bandaging phase. The timing ranges from five to 14 days after surgery, determined largely by where on the body the wound is located and what kind of repair was performed.6Archives of Dermatology. A Prospective Evaluation of the Incidence of Complications Associated With Mohs Micrographic Surgery Facial sutures tend to come out sooner because the face has excellent blood supply and heals quickly. Sutures on the trunk or extremities stay in longer because those areas are under more tension and heal more slowly.
After suture removal, some surgeons apply adhesive wound-closure strips (Steri-Strips) across the incision line and ask you to keep them on for another week to give the scar additional support while the deeper tissue continues to strengthen. You may or may not need a bandage over those strips. Once the skin is fully closed and the strips come off, most people no longer need any bandage at all, though protecting the area from the sun remains important for months.
A wound that looks “closed” on the surface is still weak underneath. The skin regains only a fraction of its original tensile strength in the first few weeks, and full remodeling takes many months. This is why your surgeon may advise you to avoid heavy lifting or vigorous exercise for a period even after sutures are out. A premature return to strenuous activity can widen the scar.
What to Watch for While You Are Bandaging
Most Mohs wounds heal without incident, but knowing the warning signs helps you catch problems early. Some practices follow up by phone at around one week specifically to screen for signs of infection and other wound-care concerns.7PubMed Central. Process of Post-operative Telephone Follow-up Implementation for Mohs Micrographic Surgery: A Pilot Study
Bleeding is the most common early issue. A small amount of oozing when you change the bandage in the first few days is normal. Persistent or heavy bleeding that does not stop with 20 minutes of firm, steady pressure warrants a call to your surgeon’s office. People on blood thinners like warfarin, aspirin, or direct oral anticoagulants should be especially attentive, because their bleeding can be harder to control with simple pressure alone. If you take any of these medications, your surgeon likely discussed this before the procedure, but it is worth confirming whether you need a longer period of pressure bandaging or any extra precautions.
Infection is less common but more serious. Signs include increasing redness that spreads beyond the wound edges, warmth, worsening pain after the first couple of days (pain should generally be improving, not getting worse), pus or cloudy drainage, and fever. A wound that simply looks pink and slightly swollen during the first few days is healing normally. A wound that is becoming more red, more painful, and more swollen after day three or four is heading the wrong direction and needs medical attention.
Numbness or tingling around the surgical site is common and usually temporary. Mohs surgery can cut tiny sensory nerves in the skin, and sensation may take weeks or months to return fully. This is not a reason to call the surgeon urgently, but it is worth mentioning at your follow-up visit.
Staying on Track With Wound Care
Wound care after Mohs surgery is not complicated, but it is repetitive, and research suggests that people tend to slip up for predictable reasons. A prospective study of Mohs patients found that overall adherence to wound-care instructions was high, with the average score landing at about 7.4 out of 8 on an adherence scale. But among those who did fall off track, the most commonly reported reasons were feeling well (so the wound care felt unnecessary), being too busy, experiencing discomfort during the cleaning and bandaging process, and being around friends or family during social situations where wound care felt inconvenient.8PubMed. Wound Care Adherence in Mohs Micrographic Surgery: A Prospective Cohort Study
“Feeling well” is the most understandable trap. Once the initial soreness fades after a few days, the wound may look fine and the whole routine can start to feel like overkill. But the wound is still actively rebuilding tissue beneath the surface, and skipping the ointment or leaving the bandage off because things “look good” can slow healing and increase scarring. The same study found that older patients and those who had someone helping them with wound care were more likely to stay adherent, which makes sense: a second person provides both a reminder and a pair of hands for hard-to-reach spots like the back of the scalp.
If the cleaning step is the part you dread, ask your surgeon about simplifying it. Some clinics have moved away from hydrogen peroxide in favor of plain gentle soap and water, which stings less. Using non-stick dressings (like Telfa pads) instead of plain gauze also helps, because standard gauze can bond to the wound surface and hurt when you pull it off. Small adjustments to comfort make a real difference over a week or two of daily repetitions.
Scar Care After the Bandage Phase Ends
Once the wound is fully closed and you no longer need a daily bandage, you enter a different phase of care aimed at minimizing the long-term appearance of the scar. The scar will continue to mature and change for six months to a year. It typically looks its worst at around four to eight weeks, appearing pink or red and slightly raised, and then gradually flattens and fades.
The two over-the-counter scar treatments with the most published evidence behind them are silicone-based products (gels or sheets) and paper tape applied along the scar line. Even so, the evidence for both is described in the literature as conflicting and limited.9PubMed. Summary and evidence grading of over-the-counter scar treatments That does not mean they are useless. Silicone sheets and gel are widely recommended by dermatologists and surgeons for hypertrophic scars (scars that become raised and thickened), and many patients report improvement. The evidence is just not strong enough for anyone to guarantee results. Onion-extract products (like Mederma) and vitamin E, while heavily marketed, have even less evidence supporting their effectiveness.
Sun protection is arguably more important than any topical scar product. New scar tissue is highly susceptible to sun damage, and UV exposure during the first year can cause permanent darkening (hyperpigmentation) that makes the scar far more visible. A broad-spectrum sunscreen with SPF 30 or higher applied to the scar whenever you go outside, or a physical cover like a hat or adhesive bandage, is the simplest thing you can do to give yourself the best cosmetic outcome. This is especially relevant for Mohs surgery, which is most commonly performed on sun-exposed areas like the face, ears, and scalp.
When Bandaging Takes Longer Than Expected
Some wounds just take longer, and that does not always mean something is wrong. Wounds on the lower legs heal notoriously slowly because blood circulation is weaker there. Large second-intention wounds on the scalp or forehead can take two to three months to close fully, particularly if bone was exposed during the surgery. Patients with diabetes, those on immunosuppressive medications, and people who smoke all tend to heal more slowly.
If your wound is still open and requiring bandages well past the timeline your surgeon initially estimated, bring it up at your follow-up appointment. Sometimes the wound just needs more time. Other times, something correctable is going on: the wound may be too dry because you are not applying enough ointment, there may be a low-grade infection that is not obvious, or a suture that was supposed to dissolve has not and is irritating the tissue. Your surgeon has seen thousands of these wounds and can usually tell quickly whether the pace of healing is within the normal range or needs intervention.
Some patients develop what is called a “stalled wound,” where healing seems to plateau. This is more common with larger second-intention wounds. The fix is often just optimizing what you are already doing: ensuring the wound stays consistently moist, cleaning it gently to remove any buildup of dead tissue, and covering it reliably with an occlusive dressing rather than leaving it exposed to air. In rare cases, your surgeon may suggest a more advanced wound-care product or even a delayed surgical closure if the wound is not progressing.
