When to Start Surgical Scar Removal? | [Yonsei Star Dermatology Sinchon]

Surgical scars are different from simple skin marks. Because they are deep wounds that penetrate the skin and muscle layers, they almost always leave a distinct trace, though the degree may vary. Therefore, many people first wonder, "When should I start treating this scar?" To put it simply, surgical scar treatment, like general scar treatment, can lead to better results when started early.

The stage before a scar fully forms is often called PreScar. Starting preventive treatment during this period, before the wound heals and hardens into a scar, is advantageous for minimizing the trace. Therefore, for surgical scars, we recommend planning treatment tailored to the individual's scar condition right after suture removal, approximately 1-2 weeks after surgery.

For red scars immediately after surgery, vascular laser (Vbeam Prima) treatment is used to suppress vascular proliferation and prevent excessive scar formation. This initial stage of calming the redness significantly influences the subsequent shape of the scar.

Even among scars, surgical scars are reported to be more difficult to treat than burn scars or general scars. The biggest reason is the depth of the scar.

Due to their depth, treatment periods can be long, and satisfaction may sometimes be lower. However, precisely because the damage is deep, there is also greater potential for improvement with appropriate treatment.

For thin, long surgical scars, the approach involves selecting a laser appropriate for the individual's skin condition and scar type to blur the boundary with normal skin. In such cases, it is essential to use a laser that can deliver heat to deep skin layers, and it is safer to receive treatment from a dermatologist specializing in scar treatment.

Surgical scars do not appear in just one form. The approach changes depending on their type.

• Red Scars: Vascular laser treatment to suppress vascular proliferation and calm redness.
• Keloid Scars: Cases where collagen is overproduced, causing the scar to swell beyond its original boundaries.
• Depressed Scars: Uneven or sunken areas due to adhesion at the suture site.
• Thin, Long Scars: Lasers to refine the edges, reducing the height difference with normal skin.

Keloid scars refer to cases where collagen is overproduced, causing the scar to swell beyond its boundaries and appear red. In such instances, a combined approach is used: Triamcinolone Scar Injection reduces abnormally accumulated collagen to shrink the hypertrophic scar, and vascular lasers simultaneously address the redness. This approach is reported to improve keloid scars that form after surgery.

In clinical practice, it is common to see a mix of red and depressed areas within a single person's scar. Therefore, rather than relying on a single device, treatment is often designed to address different aspects of the scar.

After surgery, skin adhesion at the sutured area can lead to uneven or depressed scars. These depressed scars are approached by lifting the sunken skin layer and refining the surface.

A representative method is Subcision. This involves cutting the fibrous bands pulling the skin down, allowing the depressed area to rise, followed by combined treatment with lasers to smooth out any remaining irregularities as much as possible. For deep depressions or stretched scars, Surgical Scar Revision may also be considered.

Surgery and laser treatments each have distinct advantages and disadvantages. One is not always the correct answer; the choice depends on the scar condition and individual constitution.

Laser treatment offers meaningful changes with relatively fewer side effects and is less burdensome as a non-surgical method. However, the need for multiple periodic treatments is considered a drawback.

Conversely, surgery can reduce the size of a scar in one go, but over time, the sutured area may reopen due to skin tension. If you are prone to scarring, the scar may recur or enlarge in the same spot, so it is advisable to consult thoroughly with medical staff before making a careful decision.

Before undergoing surgical scar treatment, it is helpful to know the following:

• It is difficult to completely erase a scar without a trace; the approach is to correct it so it is less noticeable.
• Results may vary individually depending on constitution and skin condition.
• Scar patterns change during treatment, so rather than sticking to one method, adjustments are made according to progress.
• Rather than trying to finish in a short period, consistently combining treatments appropriate for the scar type tends to be more stable.

Treatment methods vary for each person based on constitution, suture condition, and skin condition. Therefore, rather than pushing for a single treatment method known to be effective, consulting thoroughly with a dermatologist to design a personalized combined treatment leads to the best results.

If it is difficult to gauge what stage your scar is at and which method is right for you, we recommend confirming your condition first rather than making a judgment alone.
