Cesarean section keloid: prevention, treatment, and care

A cesarean section keloid is one of the most frequent scar complications of obstetric surgery. The good news: with early care in the first 60 days, most can be prevented — and even a pre-existing keloid has multiple treatment options.

Why does cesarean section favor keloid formation?

Three combined factors explain this:

• Constant tension in the suprapubic region — movements, abdominal weight, and the uterus's return generate mechanical stress that stimulates excess collagen.
• Genetic predisposition — personal or family history of keloids greatly increases the risk.
• Hormonal factors of pregnancy and breastfeeding influence wound healing.

Who is at higher risk?

• Personal history of keloids (in any area)
• Close family history
• Darker skin (phototypes IV, V, VI)
• Younger women (under 30 years old)
• Cesarean section with complications: infection, dehiscence, hematoma
• Patients with multiple cesarean sections in the same location

How to prevent in the first 60 days

The most critical period for prevention is between 4 and 8 weeks after surgery, when fibrosis is forming.

1. Silicone sheets or gels starting from the 4th week, continuous use for at least 3 months. Proven action to reduce thickness, redness, and itching.
2. Scar massage 2x a day, in circular movements, after the 30th day.
3. Sun protection SPF 50+ for 12 months — sun worsens scars on any skin type.
4. Abdominal binder as per obstetric guidance to reduce tension along the incision line.
5. Continuous hydration of the scar.

Early signs of keloid

• Scar that continues to elevate after the 2nd month
• Persistent and intense itching
• Progressive hardening and redness
• Growth beyond the edges of the original incision

If any of these signs appear, it is ideal to seek evaluation within 2 weeks — the earlier treatment begins, the better the result.

Treatments for pre-existing keloids

First line: silicone + corticosteroid

Standard combination: continuous silicone sheet or gel + monthly triamcinolone injection for 3 to 6 sessions. Reduces volume, itching, and redness in most cases.

Laser

Vascular laser (PDL) reduces redness. Fractional ablative laser improves texture and allows for drug delivery (potentiates corticosteroid infiltration).

Cryotherapy

Controlled freezing for smaller keloids; can be combined with infiltration.

Surgery

Indicated for large or refractory keloids. NEVER isolated — recurrence in up to 80% of cases. Always associated with corticosteroid infiltration peri- and post-operatively, continuous silicone, and, in selected cases, adjuvant low-dose radiotherapy.

When to seek specialized evaluation

• Cesarean scar continues to grow after 2 months
• Persistent itching or pain
• Elevated, hard, reddish scar
• Significant aesthetic discomfort
• History of keloids and planning for a new cesarean section

Frequently asked questions

Why do keloids appear after a cesarean section?

The suprapubic region is a zone of constant tension (movements, pregnancy, abdominal weight), which favors hypertrophic scars and keloids. Genetic predisposition, darker skin, young age, and wound infection increase the risk.

How to know if it's a keloid or a hypertrophic scar?

A hypertrophic scar is elevated but remains within the limits of the incision. A keloid extends beyond the edges, grows beyond the trauma, usually itches and hurts, and tends to recur after surgery if not treated in a combined manner.

When should treatment begin?

Ideally between 4 and 8 weeks after the cesarean section, as soon as the wound is closed. Start prophylactic silicone sheets or gel at this time, especially if there is a personal or family history of keloids.

What is the best treatment for a cesarean section keloid?

Combination is the rule: continuous topical silicone + monthly corticosteroid (triamcinolone) infiltration for 3-6 sessions. For large keloids, laser, cryotherapy, or surgery + radiotherapy are associated for refractory cases.

Can I have abdominoplasty to remove the keloid?

Yes, but isolated surgical removal without additional protection has a high recurrence rate (up to 80%). The ideal is to plan the surgery along with peri- and post-operative corticosteroid infiltration, continuous silicone, and, in some cases, adjuvant radiotherapy.
