A scar is the body’s natural response to deep tissue injury, where fibrous tissue replaces damaged skin to restore structural integrity. Plastic surgeons operate with the philosophy that a scar cannot be completely erased, but it can be significantly minimized and managed to be as inconspicuous as possible. This requires a multi-modal approach, combining careful surgical technique with diligent post-operative care and, often, subsequent revisions. The initial quality of the repair and the patient’s immediate aftercare set the stage for the final appearance.
Optimizing the Healing Phase
The initial weeks following an injury or surgery influence the final scar quality. Surgeons employ meticulous techniques, such as using fine sutures and placing incisions along the relaxed skin tension lines, to minimize forces pulling on the wound edges. Dissolvable sutures are frequently used in deeper layers to remove tension from the skin’s surface. This allows the superficial layer to heal flat and narrowly.
Once the wound has fully closed, typically around two to three weeks post-procedure, gentle scar massage should begin. Massage involves applying pressure across the scar line to manually break down the disorganized, dense collagen fibers that create a raised or rigid scar. Performing cross-friction massage for ten minutes twice a day helps to realign these fibers. This promotes a softer, flatter, and more pliable texture.
Sun protection is a vital long-term aftercare step. New scars are highly susceptible to ultraviolet (UV) radiation, which can trigger permanent pigment deposition, resulting in discoloration called hyperpigmentation. Surgeons recommend applying a broad-spectrum sunscreen with an SPF of 30 or higher daily for at least six to twelve months. Alternatively, the scar should be kept covered by clothing.
Non-Surgical Topical Applications
Topical treatments are used for scar management, with the gold standard being medical-grade silicone. Silicone is available as adhesive sheets or self-drying gels. It is primarily effective on elevated scars like hypertrophic and keloid scars, working through occlusion and hydration of the tissue.
By creating a semi-occlusive barrier, silicone reduces transepidermal water loss (TEWL) from the scar, which signals to the underlying cells to decrease excessive collagen production. This results in a flatter, softer, and less red scar over time. For maximum benefit, silicone products should be worn consistently for twelve to twenty-four hours a day over several months.
In contrast to silicone, Vitamin E oil is viewed with skepticism. Scientific studies show no consistent benefit of topical Vitamin E compared to a simple moisturizer. Moreover, many patients experience contact dermatitis, which can cause an itchy rash that worsens the appearance and delays healing.
In-Office Procedural Treatments
For scars that remain raised, discolored, or indented despite diligent home care, a plastic surgeon can recommend procedural treatments. Intralesional corticosteroid injections, typically using triamcinolone acetonide, are the first-line treatment for reducing the height and inflammation of hypertrophic scars and keloids. The steroid is injected directly into the tissue, reducing collagen synthesis and breaking down existing collagen bonds. This leads to a flatter and softer lesion.
Laser treatments offer targeted solutions. Vascular lasers, such as the Pulsed Dye Laser (PDL), target tiny blood vessels within immature or hyper-vascularized scars to reduce redness (erythema). Fractional lasers, including ablative (like CO2) and non-ablative types, are used for textural improvement.
Fractional lasers work by creating microscopic zones of injury in the skin, which stimulates the body’s own collagen remodeling process to smooth out surface irregularities. For depressed scars, such as those left by acne, dermal fillers are injected beneath the indentation to immediately restore volume. Hyaluronic acid fillers lift the sunken tissue to the level of the surrounding skin, minimizing shadows and creating a smoother contour.
Scar Revision Surgery
Scar revision surgery is reserved for scars that are wide, long, poorly aligned with natural skin folds, or those that cause functional impairment like contractures across a joint. The procedure involves excising the existing scar and meticulously closing the wound to create a less noticeable mark. The core concept is to reduce tension on the healing wound, which is the primary driver of poor scarring.
Techniques like Z-plasty or W-plasty are employed to change the orientation of a linear scar that runs perpendicular to the skin’s natural tension lines. Z-plasty involves transposing triangular flaps of skin to reorient the central portion of the scar into a less visible direction and lengthen a tight, contracted scar. W-plasty uses a series of small, interlocking triangles to break a straight line into a less conspicuous, irregular pattern that blends more seamlessly with skin creases.
