The Mohs Wound Healing Timeline: A Guide for New Hampshire & Massachusetts Patients

You’ve been told you need Mohs surgery, or perhaps you’ve just had the procedure. Now, as you look at the bandage, a completely normal and very common question pops into your head: 

“What is this going to look like as it heals?”

It’s a question our patients ask all the time. Whether you're driving home to Dover or resting up in Peabody, understanding the healing process is the first step toward feeling confident and in control. The journey of a Mohs surgical wound closure on human skin over time isn’t a mystery—it’s a predictable biological process.

Let’s walk through that timeline together, so you know exactly what to expect.

Your Healing Journey: A Week-by-Week Look

Every patient and every wound is unique, but the stages of healing follow a general pattern. Your surgeon's specific aftercare instructions are your most important guide, but this timeline will give you a clear picture of what’s happening beneath the bandage.

The First 48 Hours: The Foundation Stage

This is the very beginning of the repair process. Your body’s first responders are on the scene.

• What you’ll see: The area will be covered by a pressure dressing to minimize bleeding and swelling. When you change it as instructed, you'll see a fresh wound, likely with sutures. Redness, mild swelling, and a bit of tenderness are all perfectly normal.
• What’s happening: Your body is focused on stopping any bleeding and forming a clot. This clot is the scaffold upon which all new tissue will be built.
• Your role: Rest. Avoid strenuous activity—this is not the time to tackle a big project in the yard or take a brisk walk around Willand Pond in Dover. Follow your wound care instructions to the letter.

Week 1: The Active Building Phase

Your body is now in full construction mode, a phase called proliferation.

• What you’ll see: You’ll notice the edges of the wound starting to pull together. A scab may form, which is nature’s own bandage. The area might look pinker and feel itchy—a sign of active healing!
• What’s happening: New blood vessels are forming to bring oxygen to the site, and cells are producing collagen to create new granulation tissue. This new, fragile tissue is what fills the wound.
• Your role: Keep the area clean and moisturized as directed. That dry winter air we often get in Londonderry can make skin feel tight, so proper care is crucial. If you have sutures, you’ll likely have them removed toward the end of this week.

Weeks 2-4: The Remodeling Begins

The initial "filling" work is done, and now the refinement process starts.

• What you’ll see: The scab will have likely fallen off on its own. The new skin underneath will be pink or reddish and might be slightly raised. It will feel delicate to the touch.
• What’s happening: The initial, weaker collagen is being replaced with stronger, more organized collagen. This is the start of scar maturation, a process that takes many months.
• Your role: Sun protection is now your #1 priority. This new skin has very little natural defense against UV radiation. Whether it’s a bright summer day on the Seacoast or a surprisingly sunny winter afternoon while running errands in Derry, you must protect the healing area. A broad-spectrum sunscreen of SPF 30+ is essential to prevent the scar from darkening and to ensure the best possible cosmetic result. The Skin Cancer Foundation offers great resources on why this is so critical.

Month 1 to Year 1 (and Beyond): The Final Result

Patience is key during this final, longest phase of healing.

• What you’ll see: Over the next 12 to 18 months, the scar will gradually soften, flatten, and fade in color from pink or red to a paler, less noticeable line.
• What’s happening: The collagen network continues to remodel and mature, becoming stronger and more flexible.
• Your role: Continue with diligent sun protection and follow any instructions for scar care, such as gentle massage, which can help improve the final appearance.
