Suture scars are traces that can form during any process of incising and re-stitching the skin. Those who have undergone suturing due to surgery or trauma often ask one main question: "It's already been a while, will treatment still help?" To answer directly, even if it's not immediately after suturing, and even if the mark has settled with a change in color, there is reported potential for improvement.
When the skin is severely torn by strong impact, or when incision is unavoidable due to surgery, the process always concludes with suturing. No matter how meticulously sutured, over time the area can widen and develop into raised forms like hypertrophic scars or keloids. Therefore, for suture scars, how you manage the "few months of recovery" is more important than "immediately after stitching."
Why Do Suture Scars Remain?
Suture scars are somewhat inevitable after surgery. However, their extent varies greatly depending on the area and post-operative care. Today, we will summarize various checkpoints, including methods to reduce scars after surgery, whether old marks can be treated, the timing of treatment, and post-care.
Generally, stitches are removed 1-2 weeks after surgery. The primary medical treatment process concludes at this point, but the skin's own regeneration continues for several months, sometimes up to a year, thereafter. The key point is that this regeneration process does not always lead to good results.
Red Scars, a Signal from Blood Vessels
If blood vessels that induce regeneration proliferate excessively, red-tinged scars can form. In the clinic, we often see patients most concerned about "red, prominent marks," which are approached by reducing and constricting the increased blood vessels. We begin the first stage of treatment with Vbeam Prima, which selectively acts on blood vessels.
It is reported to be more advantageous to start early. However, suture scar laser treatment can only be performed after stitches are removed, making it virtually impossible to start immediately after surgery. Nevertheless, even marks that have been present for some time still have potential for improvement, so there's no need to be overly anxious.
Red scars are often a problem of blood vessels, not pigment. Rather than attempting whitening or regeneration indiscriminately, reducing redness first is considered fundamental to scar management.

The Real Cause of Scar Enlargement: Tension
'Tension' is cited as a reason why scars tend to form easily on the face or body. Tension refers to the pulling force on the skin. The face generally has weaker tension, resulting in fewer scars, while the arms, legs, and torso experience strong tension, which can worsen scars.
Immediately after surgery, your condition is weaker than usual. If you don't rest sufficiently and engage in strenuous exercise, the skin is greatly affected by tension, increasing the likelihood of prominent suture scars. Please consider giving your skin time to recover as an essential part of the treatment process.
To prevent scars from worsening immediately after suturing, check the following:
- Avoid movements or postures that pull the sutured area until stitches are removed.
- Postpone strenuous exercise and excessive activity during the early recovery period.
- Protect the area with ointment or hydrocolloid bandages recommended by medical staff.
- Be mindful of UV protection, as sunlight can exacerbate changes in scar color.
- If redness or elevation worsens, seek medical consultation instead of self-diagnosing.
Is Treatment Possible for Old, Discolored Scars?
Many scars initially appear red but gradually turn white, solidifying into a noticeable form. Even if the color has changed, treatment effects are reported, so there's no need to give up prematurely. However, it is generally more advantageous for management to start as early as possible.
After the first stage of treatment to reduce redness, different types of suture scar lasers follow. Lasers that aid skin regeneration, such as Ultrapulse Encore or StarLux, are used to match the color with the surrounding healthy skin and naturally refine the mark.

Suture Scar Laser Treatment by Stage
Not just one type of laser is used for treatment. Lasers with different mechanisms are applied in stages according to the scar's condition.
| Stage | Problem Addressed | Approach |
|---|---|---|
| Stage 1 | Redness, increased blood vessels | Redness reduction with vascular-selective laser |
| Stage 2 | Differences in color and texture | Tone refinement with regenerative laser to match surrounding skin |
| Post-care | Regeneration, protection | Concurrent home care with ointment and hydrocolloid bandages |
If consistently treated with methods appropriate for the condition, even if complete erasure of the trace is difficult, results show natural refinement to a point where it is less noticeable. If raised scars are also present, understanding Characteristics of Keloid Scars can help in determining the treatment direction.
Post-Care That Determines Results
An advantage of this method is that it can refine traces with reduced burden, even if it takes some time. Adding home care that uses ointments or hydrocolloid bandages to aid skin regeneration and protect the wound from external stimuli can enhance the completeness of the treatment.
If you are considering related treatments, where you receive them is also an important point. Please remember that you can expect satisfactory results by choosing a dermatology clinic with the experience and know-how to accurately assess your condition and perform necessary procedures in stages. In cases where surgical scars are prominent, Surgical Scar Revision to refine the incision again, or Triamcinolone Scar Injection used for raised scars, may also be considered.
