Most Mohs surgery wounds heal enough for daily activities within two to four weeks, but the full healing process continues beneath the surface for up to two years. The exact timeline depends on where on your body the surgery was performed, how large the wound is, and how it was closed.
The First 48 Hours
The first two days after surgery are when you’re most likely to experience bleeding or swelling. The risk of a hematoma, a pocket of blood forming under the wound, peaks during this window. Signs to watch for include increasing pain, warmth, and a growing lump under or near the closure site. If your surgery was near the eye or on the neck, any expanding swelling needs immediate medical attention because of the critical structures in those areas.
Pain is typically most noticeable during these first few days. Alternating acetaminophen and ibuprofen every three hours (so you’re taking one or the other every three hours, cycling between the two) for the first three to four days is a common approach for managing discomfort. Most people find they can taper off pain relief after that initial stretch.
Weeks One Through Four
Your activity level matters during recovery. Plan to avoid strenuous exercise and heavy lifting for at least a week after surgery, though your surgeon may extend that timeline depending on the wound’s size and location. Bending over, straining, or raising your blood pressure with intense activity can reopen the wound or trigger bleeding.
If you have stitches, they’re typically removed within one to two weeks for facial wounds. Stitches on the scalp, trunk, or limbs often stay in a bit longer. Even after stitches come out, the wound is still fragile. The skin has closed, but the underlying tissue is actively rebuilding collagen and is far from full strength.
During this phase, keeping the wound moist with plain petrolatum (like Vaseline) is the current standard of care. Topical antibiotic ointments on sutured wounds don’t reduce infection rates and can actually cause contact dermatitis, so petroleum jelly is the safer choice for most people.
How Closure Method Affects Healing
The way your surgeon closes the wound has a significant impact on both healing time and the final cosmetic result.
- Primary closure (stitching the edges together) is the simplest option when the wound is small enough. It heals fastest and typically leaves the smallest scar.
- Local skin flaps involve moving nearby tissue to cover the wound. Because the donor skin matches the surrounding area in color and texture, flaps often produce the best cosmetic outcome. The tradeoff is a longer incision line and slightly more recovery time.
- Skin grafts use skin taken from another part of your body. They’re useful for areas like the nasal tip or lower eyelid where flaps aren’t always practical. Grafts tend to heal with a noticeable difference in texture and color compared to the surrounding skin, and patients most often report dissatisfaction with that mismatch.
- Secondary intention (letting the wound heal on its own without stitches) is sometimes the best option for certain locations or wound shapes. These wounds take longer to close because the body fills in the gap gradually from the bottom up. Healing can take several weeks to months depending on wound size.
Scar Changes Over Months
What surprises many people is how much the scar continues to change long after the wound looks “healed.” In the first few weeks, even after stitches are out, the scar is typically red, swollen, and feels rubbery or firm to the touch. This is normal. Your body is flooding the area with new collagen to rebuild strength.
By one month, the scar is usually much less noticeable. By six months, it’s often quite subtle. But the remodeling process keeps going well beyond that. Scars continue to soften, flatten, and fade for up to two years. During this entire period, the tissue is reorganizing its internal structure. So if your scar looks pink or slightly raised at the three-month mark, that’s not the final result.
Signs of Infection
Infection is one of the more common complications after Mohs surgery. Watch for increasing redness that spreads beyond the wound edges, warmth, swelling that gets worse instead of better, pus or cloudy drainage, and fever. Mild infections are typically treated with oral antibiotics. More severe infections with visible dead tissue may require additional wound cleaning. If you notice any of these signs, especially drainage with an odor, contact your surgeon’s office rather than waiting for your follow-up appointment.
What a Realistic Recovery Looks Like
Most people return to work and light daily activities within a few days to a week. The wound itself closes within two to four weeks for sutured repairs, longer for wounds healing by secondary intention. But “healed” is relative. The surface may look intact while the deeper layers are still weeks away from regaining meaningful strength. Protecting the area from sun exposure during the entire scar maturation period (up to two years) helps prevent the scar from darkening permanently.
The biggest variable in your recovery is wound size and location. A small primary closure on the forehead heals differently than a large flap repair on the nose. Your surgeon can give you a more specific timeline based on your particular wound, but the general arc is the same: functional healing in weeks, cosmetic improvement over months, and final scar maturation over one to two years.
