What to Expect From an Open Heart Surgery Scar
After open heart surgery, a visible scar forms down the center of the chest where the sternum was accessed. This median sternotomy scar varies in length but generally runs from just below the collarbone to the upper abdomen. It is the most common approach for many heart surgeries.
In the first weeks, scars appear red, swollen, and slightly raised. Numbness or tingling around the incision is normal due to disrupted nerves and tissue healing. As time passes, the scar usually flattens, softens, and fades, though it may always be somewhat noticeable.
The Healing Process: Timeline & Key Changes
Week 1–2: Immediate Post-op
The skin is closed with sutures or staples, shielded by a sterile dressing. Some oozing or clear fluid is normal, but active bleeding or pus is not. The surrounding skin may be bruised. Gentle movement is important to boost circulation and support recovery.
Weeks 2–6: Early Scar Formation
Sutures or staples are usually removed by week 2. The scar may be itchy as nerve endings regenerate and the skin pulls together. It’s crucial to avoid picking or scratching. Most wounds are sealed by week 3.
Months 2–6+: Maturation Phase
The body remodels the scar: color fades from red or purple to a paler tone, height and firmness decrease. Over several months, scars become less sensitive but can remain visible as a fine line or thickened band. Full fading may take a year or more, especially in dark or keloid-prone skin.
7 Essential Care Tips for Your Scar
- Keep the scar clean and dry: Gently wash daily with mild soap and water; pat dry.
- Avoid direct sunlight: Cover with clothing or use high-SPF sunscreen to prevent discoloration.
- Don’t pick or scratch: Leave scabs and flakes—disturbing them increases infection and poor healing risk.
- Moisturize regularly: After healing, use fragrance-free creams to soften scar tissue and improve flexibility.
- Watch for infection signs: Redness, warmth, swelling, pus, or fever need urgent medical review.
- Follow activity guidance: Avoid heavy lifting until cleared by your surgical team.
- Massage when healed: Gentle massage (once approved) helps reduce scar hardness and discomfort.
Strict adherence to these care steps supports normal healing and lowers the chance of long-term cosmetic or health issues.
Potential Problems and When to Seek Help
While most open heart surgery scars heal as expected, complications can arise. Infection is the main risk early on: painful redness, pus, wound opening, or a high fever should prompt immediate doctor review. Delaying care can lead to deeper chest infections or even systemic illness.
Some people experience abnormal scarring—either a hypertrophic (raised, red, thickened) scar or a keloid (scar tissue growing beyond the original wound). These usually develop in the months after surgery, especially in genetically-prone individuals or those with darker skin.
Another challenge is scar dehiscence—when the wound reopens. This is rare and requires urgent management. Noticing new drainage, widening of the scar, or persistent pain? Seek prompt medical advice.
Scar Minimization: What Actually Works?
Most Evidence-Based Methods
- Silicone sheets or gels: These products, worn daily, have the strongest evidence for flattening and fading scars when used for several months.
- Massage therapy: Once your provider approves, regular gentle massage can break down scar tissue and soften texture.
- Sun protection: Regularly shielding the scar from sun prevents long-term darkening or hyperpigmentation.
Unproven or Less Effective Strategies
- Vitamin E lotions and herbal remedies: Research does not support these for improving surgical scars.
- Scar removal creams: Over-the-counter products rarely outperform basic moisturizers unless they contain silicone.
For problematic scars, dermatology options include steroid injections, laser treatments, and surgical revision, but these are only considered if non-invasive care fails—and only after full healing.
Frequently Asked Questions
What should an open heart surgery scar look like after one month?
It’s usually pink or red, somewhat raised but sealed with no drainage. Some itching or tightness is normal, but worsening redness or pus is not—contact your clinical team if concerned.
How long before I can shower after surgery?
Most patients shower 3–7 days after surgery; always follow your team’s guidelines about wound dressing and getting the scar wet. Baths and swimming are not recommended until the wound is fully closed.
Is it normal for the scar to feel numb or tingly?
Yes—nerves can take a long time to recover. Sensation often improves slowly over several months, but some reduced feeling may be permanent.
Can I use over-the-counter scar creams?
Simple moisturizers or silicone gels are usually safe after initial healing. Avoid harsh or fragranced products; always test on a small area first and consult your provider if unsure.
How do I know if my scar is infected?
Key signs are increasing pain, swelling, warmth, pus, or fever. If any of these develop, seek medical advice quickly to prevent more serious complications.

Social & Psychological Factors: Coping with a Visible Scar
A prominent open heart surgery scar can affect confidence, body image, and even relationships. It’s normal to feel self-conscious, especially in the early months. Many patients report that time, acceptance, and open discussion with loved ones or support groups help greatly.
Cultural or personal attitudes about scarring vary. Some view scars as signs of survival—it can help to remind yourself of the major challenge you overcame. If feelings of embarrassment or distress persist, ask your provider about mental health support or peer networks for surgical patients.
