When it comes to C-section scar care, the guidance of dermatologists and surgeons is invaluable. The incidence of abnormal scarring, i.e., keloid or hypertrophic scar formation after caesarean section is reported to be approximately 41%. Abnormal or excessive scar formation can lead to functional limitations, pruritus, pain and cosmetic issues. Understanding what medical professionals recommend can help you achieve the best possible healing outcomes.
Silicone-based products such as sheets and gels are recommended as the gold standard, first-line, non-invasive option for both the prevention and treatment of scars. Other general scar preventative measures include avoiding sun exposure, compression therapy, taping and the use of moisturisers.
In addition to optimal surgical management, this includes measures to reduce skin tension, and to provide taping, hydration and ultraviolet (UV) protection of the early scar tissue. Silicone sheeting or gel is universally considered as the first-line prophylactic and treatment option for hypertrophic scars and keloids.
Research consistently supports this approach. Of the 16 trials investigating silicone gel sheets, numerous high-quality RCTs found that silicone gel sheets and silicone gels significantly improved scar outcomes.
Adhesive tape support and silicone gel sheeting maintain hydration and occlusion, with silicone gel preferred for its ease of use. Intralesional corticosteroid injections, mainly triamcinolone acetonide, effectively treat keloids and hypertrophic scars, though side effects are common.
Silicone has been used for more than 30 years in the treatment of cutaneous scars. Another physical mode of action provided by silicone gel sheeting is transferring tension from the lateral edges of the wound bed to the silicone gel sheet. The gentle reduction in tension which can be provided by an adhesive silicone gel sheeting provides the ideal environment for normal scar development and can significantly reduce the rate of abnormal and keloid scarring.
Conservative treatment procedures such as scar massage and compression therapy using compression dressings or scar plasters containing silicone are gold standard therapies to obtain flat, soft, and aesthetically acceptable scars. Furthermore, for functional rehabilitation, physiotherapy and occupational therapy remain integral treatment pillars.
Scar management encompasses various conventional treatments, each with its specific mechanisms and outcomes. Massage therapy, despite limited scientific evidence, is commonly used to alleviate scar-related pain and improve mood. Pressure garments, another standard therapy, reduce collagen synthesis through mechanical compression but have low patient adherence due to discomfort. Adhesive tape support and silicone gel sheeting maintain hydration and occlusion, with silicone gel preferred for its ease of use.
For the treatment of existing hypertrophic scars, silicone, pulsed-dye laser, CO2 laser, corticosteroids, 5-fluorouracil, bleomycin, and scar massage have high efficacy, whereas onion extract and fat grafting seem to have low efficacy.
One of the most significant advances in scar management over the past 10 years has been the broader application of laser therapy, resulting in a shift in status from an emerging technology to the forefront of treatment. Accumulated clinical evidence also supports a greater role for 5-fluourouracil in the treatment of hypertrophic scars and keloids, particularly in combination with intralesional corticosteroids.
Laser therapy depicts a safe and effective first-line therapy in the management of traumatic scars and contractures.
Steroid injections have been used for years for keloids and hypertrophic scars. Typically triamcinolone is used. The steroid is diluted to a concentration of 2.5mg/mL. Approximately 0.1 mL is injected per 5 to 8 mm of a linear scar. Patients are instructed to massage the area for 24 hours after injection. Injections occur every 4 weeks.
Management of incisional scar is intimately connected to stages of wound healing. The management of an elective surgery patient begins with a thorough informed consent process in which the patient is made aware of personal and clinical circumstances that cannot be modified, such as age, ethnicity, and previous history of hypertrophic scars. In scar prevention, the single most important modifiable factor is wound tension during the proliferative and remodeling phases.
The management of a surgical incision does not end when the sutures are removed. Surgical scar care should be continued for one year.
It is of vital importance to keep the wound clean by washing the incision and performing routine dressing changes. Well-approximated surgical incisions epithelialize within 1 to 2 days, thus washing a wound may be safely started 48 hours postoperatively and should be done daily thereafter.
An ideal scar is flat, thin, and color matched to the surrounding skin. Incision planning, skin closure, and postoperative care are vital to create an inconspicuous scar.
If an undesirable scar is still evident, revision surgery can be performed to create an aesthetically pleasing appearance. As scar maturation is a 12- to 18-month process, more conservative treatment modalities should be instituted first before discussion of scar revision. An initial nonsurgical approach to scar management may provide the desired results that would nullify the need for revision surgery.
Therefore, scar revision usually will be performed after 6 to 12 months upon formation.
Early intervention is a key to control hyperplastic response. Hypertrophic scars that do not improve by 6 months are keloids and should be managed aggressively with intralesional steroid injections and alternate modalities.
Invasive treatment options include intralesional injections of corticosteroids and/or 5-fluorouracil, cryotherapy, radiotherapy, laser therapy and surgical excision.
Prevention of scars is critical as it is much easier to prevent formation than to rely on management once the scars have formed. The first step in scar prevention is meticulous attention to presurgical details, operative procedures and postoperative wound care.

Dermatologists and surgeons agree that effective C-section scar care requires a multi-faceted approach. Starting with silicone-based products as the gold standard, combined with proper wound hygiene, massage therapy, and sun protection, you can significantly improve your scar's appearance. Remember that scar maturation takes 12-18 months, so patience and consistency are essential.
If conservative treatments don't produce satisfactory results, professional interventions like laser therapy or steroid injections offer additional options. Always consult with your healthcare provider to create a personalized scar care plan that addresses your unique healing needs.
