How Do I Take Care of My Scar?
Key Reassurances
- Most Mohs surgery scars heal very well and continue to improve for up to a year.
- Simple daily habits — sun protection, silicone, and massage — make a real difference.
- Your surgeon chose the best closure method to give you the best possible scar.
- It is completely normal for a scar to look its worst at 2–3 months before it starts to fade.
Scar Healing Timeline
Your scar will change a lot over the coming months. This is normal. Knowing what to expect can help you feel less worried.
Practical Tips
- Scars look worse before they look better — the 2–3 month mark is often the most concerning, but improvement follows
- Final results take up to a year, and sometimes longer
| Time After Surgery | What You May See |
|---|---|
| Week 1–2 | Red, slightly raised, possibly swollen. The area may feel firm or tender. |
| Month 1–3 | Peak redness. The scar may look darker or more noticeable than it will later. This is the most active healing phase. |
| Month 3–6 | Redness begins to fade. The scar starts to flatten and soften. Color shifts toward pink or light purple. |
| Month 6–12 | Mature scar. Color continues to fade toward your natural skin tone. The scar becomes softer and flatter. |
Sun Protection
Sun protection is the single most important thing you can do for your healing scar. New scar tissue is very sensitive to ultraviolet (UV) light. UV exposure can cause your scar to darken permanently — a change that is very difficult to reverse.
Practical Tips
- Apply SPF 30 or higher sunscreen to the scar every day, even on cloudy days
- Reapply every 2 hours if you are outdoors
- A physical barrier (hat, bandage, clothing) works even better than sunscreen
- Keep this up for at least 6–12 months after surgery
- Mineral sunscreens (zinc oxide, titanium dioxide) are gentle on healing skin
Silicone Products
Silicone sheets and silicone gel are the best-studied products for scar improvement. They work by keeping the scar hydrated and reducing excess collagen buildup. Studies show they can reduce raised or thickened scarring by about 50%.
Practical Tips
- Start silicone products 2–4 weeks after your stitches are removed, once the wound is fully closed
- Silicone sheets (like ScarAway) are worn over the scar for 12+ hours per day
- Silicone gel (like Kelo-Cote or Mederma Advanced) is applied in a thin layer and dries to a clear film
- Use consistently for at least 2–3 months for best results
- Both sheets and gel are available without a prescription
Scar Massage
Gentle massage helps break down the collagen cross-links that form during healing. This can soften and flatten your scar over time. It also helps reduce tightness.
Practical Tips
- Start 2–4 weeks after stitches are removed, once the skin is fully closed
- Use gentle, circular motions with your fingertip directly on the scar
- Massage for 2–3 minutes, 2–3 times per day
- You can use a moisturizer, petroleum jelly, or silicone gel during massage
- The scar may feel firm or lumpy at first — this is normal and will improve
- If massage causes pain, wait a few more days before trying again
What to Avoid
Some commonly recommended products and habits can actually make your scar worse or slow healing.
Practical Tips
- Vitamin E oil — despite its reputation, studies show no benefit for scars, and it can cause a skin rash (contact dermatitis) in some people
- Hydrogen peroxide — damages healthy new tissue and slows healing
- Picking at scabs or crusts — increases the risk of infection and a wider scar
- Tanning or unprotected sun exposure — causes permanent darkening of the scar
- Harsh scrubbing or exfoliating over the scar during the first few months
When to See Your Surgeon
Most scars heal without problems. However, contact your surgeon if you notice any of the following:
Practical Tips
- A scar that keeps growing beyond the original wound edges (this may be a keloid)
- A scar that is widening or pulling apart
- A raised, itchy, or painful scar that is not improving after 3 months
- Tightness or pulling that limits your movement (scar contracture)
- Signs of infection: increasing redness, warmth, swelling, pus, or fever
