Effective Laser Treatment for Self-Harm Scars - [Yonsei Star Dermatology Sinchon]

Scars left by self-harm are more than just skin marks; they often become reminders that force one to confront past struggles daily. The number of people visiting our clinic each year for self-harm scars has been increasing, and the most common question we hear in the consultation room is almost always the same: "Can these marks really lighten with laser treatment, and how many sessions will I need?"

To answer directly, self-harm scars are reported to lighten with laser treatment. However, the degree of improvement varies depending on the depth of the scar and individual differences, and patience over a sufficient period greatly influences the outcome.

One of the most frequently asked questions is, "How many sessions will it take to see improvement?" The answer largely depends on the criteria used. If the goal is simply to be better than the current state, even 3 to 5 laser treatments can show a gradual fading of the scars.

However, if the standard is "a satisfactory level," the story changes. While the definition of satisfaction varies from person to person, in this case, at least 10 or more treatments are often required. Even with self-harm scars, linear scars, like surgical scars, tend to have a relatively consistent treatment response.

Before starting treatment, defining "how much improvement will be satisfactory" can bring greater peace of mind. For self-harm scar treatment, the standard of satisfaction can be broadly divided into three categories:

• First, the complete disappearance of the marks.
• Second, fading to the point where they are barely visible at a glance.
• Third, even if slightly visible, appearing as scars caused by something other than self-harm.

Among these, the first, complete disappearance, is often realistically difficult. While dozens of treatments can lead to near-invisibility, aiming for that as the sole goal can be a significant burden. Therefore, realistic goals are the second or third, which, despite individual differences, can generally be achieved with about 10 to 20 treatments. We may also consider combining Surgical Scar Revision or Laser + Revision Combination.

There is an important point to be aware of when treating self-harm scars, including those on the wrist, with lasers. There may be a period during the treatment process when the scars appear even more prominent. This is because reactions such as laser marks, temporary color changes, or skin depressions can occur.

These changes generally resolve naturally after about 6 months to 1 year. Knowing this in advance can help you proceed with treatment without wavering in the middle.

Just as important as the number of treatments is the overall duration. Assuming 10 treatments at one-month intervals, the treatment itself takes approximately 1 year. Additionally, it takes another year for the temporary prominence that appeared after the last treatment to subside, requiring a total of about 2 years for the effects to be maximized.

Therefore, if you are considering treatment before important life events such as employment or marriage, starting at least 3 years in advance is recommended to achieve results with more leeway.

Self-harm scars may appear similar on the surface, but the depth of damage varies. If the skin has sustained relatively minor damage, the scars are shallow, and treatment tends to be effective.

Conversely, if deep damage has affected muscles or ligaments, or if there are too many scars due to repeated self-harm, treatment may be slow and less effective. If the scar has hardened and risen like a keloid scar, the approach changes, so the treatment direction is determined after examining the scar's condition during the consultation.

Post-treatment care is not particularly difficult. Applying moisturizers or regenerative creams is often sufficient.

More important than care, however, is a patient mindset. Since treatment takes a long time, impatience can easily lead to giving up midway or increased stress. We recommend setting aside ample time from the beginning and proceeding with a relaxed attitude.

Here are some things to check before starting treatment:

• Aim to make the scars appear natural, not for complete removal.
• Plan for at least 10 or more sessions and a period of over 1 year in advance.
• Accept that scars may temporarily appear more prominent during treatment.
• Understand that results can vary depending on the depth and number of scars.
• If you have important events, consider starting at least 3 years prior.

Consistent and long-term treatment is paramount for self-harm scars. If you are curious about your scar condition and treatment plan, we encourage you to consult without obligation through Self-Harm Scar Treatment Consultation.
