Stitches placed after Mohs micrographic surgery typically stay in for five to fourteen days, with the exact timing depending mainly on where the wound is located on your body and the type of repair your surgeon performed. A prospective study tracking complications after Mohs procedures found that suture removal fell within that 5-to-14-day window across all surgical sites.1JAMA Dermatology. A Prospective Evaluation of the Incidence of Complications Associated With Mohs Micrographic Surgery That range is wide for a reason, and understanding what pushes your particular timeline shorter or longer can save you worry during recovery.
Why the Location of Your Wound Matters Most
The single biggest factor in how long your stitches stay in is where the Mohs procedure was done. Skin on the face has an exceptionally rich blood supply, which means it heals faster than skin almost anywhere else on the body. Stitches on the face, especially on the eyelids, nose, and ears, often come out on the shorter end of the spectrum, sometimes as early as five to seven days. The forehead and cheeks heal quickly too, though slightly thicker skin there can push removal closer to seven days.
Move below the jawline and things slow down. The neck and scalp generally need stitches for seven to ten days. The trunk, arms, and hands tend to run eight to twelve days. The lower legs are the slowest healers, partly because blood circulation is weaker that far from the heart, and partly because walking and daily movement put more mechanical stress on the wound. Stitches on the lower legs can stay in for the full fourteen days or occasionally even longer. Your surgeon will give you a specific date at the end of your procedure, and that date is calibrated to both the body site and the repair technique used.
How the Type of Repair Affects Timing
Mohs surgery removes skin cancer layer by layer, and the wound left behind can range from a small circle to a large, irregularly shaped defect. The reconstruction your surgeon chooses to close that wound plays a direct role in how long stitches need to stay in.1JAMA Dermatology. A Prospective Evaluation of the Incidence of Complications Associated With Mohs Micrographic Surgery
A simple side-to-side closure, sometimes called a linear repair, pulls the wound edges together in a straight line. These tend to heal well and stitches come out relatively early. A skin flap, where nearby tissue is shifted or rotated to fill the defect, involves more tension and more blood-supply considerations, so stitches often stay in a day or two longer. A skin graft, where tissue is taken from a donor site and placed over the wound, can require the longest stitch retention because the graft needs time to develop its own blood supply from the wound bed underneath. Graft sites on the face might keep stitches for seven to ten days, while graft sites on the legs could go up to two weeks.
In practice, your surgeon may use different stitch strategies for different layers of the same wound. The deeper layers often get absorbable sutures that dissolve on their own over weeks to months, while the surface layer gets non-absorbable stitches that need to be physically removed at your follow-up visit. This layered approach is why you might hear your surgeon mention two types of stitches even though you only see one set on the surface.
Absorbable Stitches and Alternatives That Skip the Removal Visit
Not every Mohs repair requires a return trip to have stitches pulled out. Dermatologic surgeons increasingly use materials designed to eliminate that extra visit. Fast-absorbing gut sutures, for example, are placed on the skin surface and break down on their own over roughly seven to fourteen days. They gradually loosen and fall off as the skin underneath knits together. Skin adhesives, sometimes called tissue glue, serve a similar purpose by holding wound edges together while the deeper repair heals, then they peel or flake off naturally.
Both approaches produce cosmetic outcomes comparable to traditional removable stitches for appropriate wound types, and they spare you a trip back to the office.2PubMed Central. Fast Absorbing Gut Suture versus Cyanoacrylate Tissue Adhesive in the Epidermal Closure of Linear Repairs Following Mohs Micrographic Surgery These options work best for linear closures under relatively low tension. Larger or more complex repairs, flaps, and grafts still generally rely on non-absorbable surface sutures that need to be removed by your surgical team.
Even when absorbable sutures are used on the surface, the deeper buried stitches are almost always a different absorbable material designed to last much longer. These deep sutures hold the wound together for weeks to months while collagen rebuilds, and they dissolve slowly enough that you never see or feel them go. Occasionally someone notices a stitch end poking through the skin surface weeks later, a phenomenon called “suture spitting.” It looks alarming but is usually harmless. Your surgeon can snip the exposed end in the office.
Deep Buried Sutures and Why They Matter
The stitches you see on the surface are only part of the story. In most Mohs repairs, the real structural work is done by buried stitches placed deep in the wound. These internal sutures pull the deeper tissue layers together so that the skin surface can heal with minimal tension, which is the single biggest factor in getting a thin, flat scar instead of a wide or raised one.
Surgeons choose among braided and monofilament absorbable materials, longer-lasting and shorter-lasting formulations, and even antibacterial-coated options. A review of the evidence on these choices found that the quality of existing trials comparing different buried suture types is generally poor, making it hard to declare any one material definitively superior.3Clinical and Experimental Dermatology. Dermatological surgery: an update on suture materials and techniques. Part 2 In practice, most experienced Mohs surgeons have a preferred material for each body site and repair type, and the differences in cosmetic outcome between modern absorbable sutures are small enough that the surgeon’s technique matters more than the brand of thread.
The deep sutures are relevant to your timeline because they bear most of the wound tension after your surface stitches come out. If you are told your surface stitches can come out at day seven, it is partly because the buried sutures are holding things together underneath. That is also why your surgeon will tell you to avoid heavy lifting and strenuous exercise for a period beyond the stitch-removal date. The deep sutures are strong, but they are not as strong as healthy, fully healed tissue.
What Happens When Stitches Are Removed
The removal appointment itself is usually quick and far less uncomfortable than people expect. The nurse or surgeon uses fine-tipped scissors or a blade to cut one end of each stitch, then pulls the thread through with forceps. Most people describe a slight tugging sensation but minimal pain. The whole process takes a few minutes for a typical linear repair.
Your surgical team will clean the wound and inspect it for any signs of incomplete healing. If one section of the wound looks like it needs more support, they may apply adhesive strips (Steri-Strips) to hold that area together for another few days. They will also give you instructions on caring for the scar going forward.
One common question is whether you can remove stitches yourself at home. The short answer is that you should not, even if you feel confident with a mirror and sharp scissors. Mohs repair sutures are placed with specific tension and spacing, and your surgeon needs to evaluate the wound at removal. Occasionally a stitch needs to stay in an extra day or two, or the wound needs a small additional intervention. That judgment call is hard to make on your own face.
What Happens If Stitches Stay in Too Long
Leaving non-absorbable stitches in longer than your surgeon recommends is not a safety-neutral choice. When stitches sit in the skin for too long, the body starts to form a small track of scar tissue around each suture, sometimes called “railroad track” marks or crosshatch scarring. On the face, where cosmetic outcome matters most and healing is fast, even an extra two or three days can leave visible marks that would not have formed with on-time removal.
The risk of crosshatch scarring is another reason facial stitches come out earlier than those elsewhere on the body. The face heals quickly enough that five to seven days is usually sufficient for the wound edges to hold together, and the sooner the suture material exits the skin, the less likely it is to leave permanent tracks. On the trunk or extremities, where the skin is thicker and cosmetic concerns may be less pressing, the window is a bit more forgiving.
If you cannot make your scheduled removal appointment, call the office rather than just waiting. They can often fit you in for a brief visit or give you guidance on how much flexibility you actually have. Missing the appointment by a day is rarely a disaster, but missing it by a week can affect the final scar.
Warning Signs to Watch for Before Removal Day
Mohs surgery has a low complication rate, but infections do happen, and recognizing the signs early makes a meaningful difference. In the days after surgery, some redness, mild swelling, and tenderness around the wound are normal. What is not normal is a sudden increase in pain several days in, expanding redness that spreads beyond the wound edges, warmth that was not there before, pus or cloudy drainage, or a fever. These symptoms can appear within the first few days after surgery and should prompt a call to your surgeon’s office right away.4PubMed Central. A case of streptococcal surgical site infection following Mohs surgery
The pattern of the symptoms can even hint at what type of infection is developing. A wound that was fine for the first few days and then becomes painful and swollen around days four through eight, with visible pus, is a more classic bacterial infection pattern. A wound that develops rapidly progressive pain and swelling within the first couple of days, typically without pus but with fast-spreading redness, suggests a different type of bacterial cause that warrants urgent attention.4PubMed Central. A case of streptococcal surgical site infection following Mohs surgery Either way, if something feels wrong, call the office. Early treatment with antibiotics is straightforward. Waiting until the scheduled removal appointment when you have a spreading infection is the wrong move.
Beyond infection, watch for a stitch that pops loose before your removal date. Small wounds under low tension can tolerate a lost suture without trouble, but if you notice the wound edges pulling apart, cover the area with adhesive strips and call the office to ask whether you need to come in early.
Caring for the Wound After Stitches Come Out
Once stitches are removed, the wound is not done healing. The scar will continue to remodel for months. In the first weeks after removal, the scar is often pink or red and may feel firm or slightly raised. This is normal collagen remodeling and does not mean something went wrong. Over the following three to twelve months, most scars fade, soften, and flatten substantially if given proper care.
The most important thing you can do for your scar is protect it from the sun. Ultraviolet exposure on a fresh scar can cause permanent darkening that no amount of later treatment will fully reverse. Use a broad-spectrum sunscreen with SPF 30 or higher, or cover the area with a hat or clothing, for at least six months after surgery. This single step matters more than any cream or treatment.
Beyond sun protection, the evidence supports noninvasive scar management for most Mohs repair sites. Silicone sheeting or silicone gel, applied once the wound surface has fully closed, can reduce scar thickness and redness over time. Gentle massage of the scar starting a few weeks after stitch removal helps break up collagen bundles and keep the tissue supple. Most wounds from Mohs surgery settle well with these conservative measures, and revisional surgery or laser treatment is rarely necessary.5Thieme / PubMed Central.

Patient Preferences and the Follow-Up Visit
An interesting wrinkle in the stitch-removal conversation is that patients themselves have strong opinions about whether they want absorbable or removable stitches, and those preferences correlate with practical factors. A study surveying Mohs surgery patients about their follow-up and suture preferences found that driving distance to the surgeon’s office was a significant factor in what patients preferred. People who had to travel farther were more likely to favor absorbable sutures that would not require a return visit. Patients who had previously undergone a skin excision also showed different preferences compared to first-timers, presumably because experience shaped their expectations about the removal process.6PubMed Central. Patient-stated post-operative follow-up and suture preferences after Mohs Micrographic Surgery
This matters because the follow-up visit is not just about pulling thread out of skin. It is also the point at which your surgeon checks for signs of cancer recurrence at the margins, evaluates wound healing, and catches any early complications. If absorbable sutures mean you skip that visit entirely, you may also skip an important wound check. Some surgeons address this by scheduling a brief follow-up even when absorbable sutures are used, while others rely on patient self-monitoring and a phone call if anything seems off. If your surgeon offers you a choice of suture type, it is worth thinking about whether you will reliably follow up on your own or whether a scheduled removal appointment gives you a built-in reason to have the wound professionally evaluated.
When Timing Gets Complicated
Certain health conditions and medications can shift your stitch-removal timeline. Blood thinners like warfarin, aspirin, and the newer oral anticoagulants do not change wound healing speed directly, but they increase the risk of post-operative bleeding. If a hematoma develops under the repair, your surgeon may want to see you sooner to evaluate it, even before the scheduled removal date. Conversely, the stitches themselves may stay in for the standard duration because the wound still needs structural support regardless of any bleeding complication.
Immunosuppressive medications, diabetes, and peripheral vascular disease all slow wound healing. If you take medications that suppress your immune system, or if you have poorly controlled blood sugar, your surgeon may keep stitches in for a day or two longer than the standard timeline for your body site. This is a judgment call based on how the wound looks at the follow-up visit, not a rigid formula. The goal is always the same: remove stitches late enough that the wound holds together but early enough to avoid permanent stitch marks.
Smokers heal more slowly than nonsmokers, particularly for flaps and grafts where blood supply to the repair is already compromised. If you smoke, your surgeon may extend the stitch timeline and will almost certainly recommend quitting or at least abstaining around the time of surgery. The effect of smoking on wound complications is one of the most consistent findings in surgical research, and it applies to Mohs repairs just as much as to larger operations.
Age, surprisingly, is less of a factor than most people assume. While older skin is thinner and may bruise more easily, the actual rate of wound healing in healthy older adults is only modestly slower than in younger people, particularly on the well-vascularized face. A seventy-year-old getting stitches out of a nasal repair at day seven is not unusual at all.
