A burn scar refers to a condition where the skin damaged by a burn recovers, but fibrous tissues like collagen are haphazardly arranged, resulting in a color and texture different from normal skin. To answer the most common question, "Can old burn scars be treated?", the fact that a scar is old is not a decisive factor preventing treatment.
Is it really difficult to treat old burn scars?
The reason why treating old burn scars feels challenging is not due to the passage of time. In the past, there were very few specialized burn treatment hospitals, so emergency care immediately after a burn was often not adequately performed, leading to many scars. Also, since many scar lesions were large and deep, treatment was often considered impossible.
Now, the situation is different. With the development of modern medical technology, even old and severe burn scars have become subjects for burn scar treatment. If you receive treatment from dermatological medical staff with extensive experience in burn scar treatment, using methods proven effective through numerous clinical cases, you can expect the possibility of improvement.
How do burn scars form?
Depending on the degree of the burn, skin structures such as the epidermis, dermis, hair follicles, and sweat glands are damaged. Afterward, the skin undergoes a recovery process, regenerating with fibrous tissues like collagen.
At this time, if fibrous tissues are created in a disorderly and excessive manner, the skin color, texture, and degree of clumping do not return to the smooth state of normal skin, and a scar remains. In other words, a burn scar is a matter of how tissues are rearranged during the recovery process, and re-inducing this rearrangement is the core direction of treatment.
From surgical methods to laser treatment
In the past, surgical methods such as skin grafting or tissue expansion were mainly used to reduce burn scars. However, satisfaction was often not high as the improved appearance could be unnatural.
| Approach | Method | Characteristics |
|---|---|---|
| Surgical Method | Skin grafting, tissue expansion | Used to compensate for large defects, but results may not be natural |
| Laser Treatment | StarLux, Ultrapulse Encore + Pinhole Technique | Expects improvement in color and texture by inducing skin cell regeneration |
Currently, laser treatment for burn scars is widely performed. When StarLux, Ultrapulse Encore lasers are used appropriately with the Pinhole Technique, cases of improvement in old and severe burn scars are reported.
How does the Pinhole Technique work?
The Pinhole Technique is a method that Yonsei Star Dermatology Sinchon reported to various dermatological societies in the early 2000s and has since established itself as one of the burn scar treatment methods.
The core principle of the Pinhole Technique is to create microscopic holes in the burn scar area with a high-output scar laser, gently loosening the thickly built dermal tissue and inducing the rearrangement of clumped collagen cells.
As laser energy that induces powerful skin regeneration is delivered, it helps the haphazardly clumped collagen to realign. Depending on the depth and extent of the scar, methods with adjusted intensity, such as Mild Pinhole or Pinhole Alpha, are chosen.
When symptoms are not severe, StarLux laser and Triamcinolone Scar Injection may be combined. If the scar thickness is prominent or contracture is severe, Surgical Scar Revision may be considered together.
The pattern of burn scars varies from person to person, so which treatment to apply and in what order is determined through consultation. In the examination room, even for burns on the same area, the depth and degree of contracture are all different, so treatment plans usually vary accordingly.

The most important thing in treatment
Consistency is the most important common factor for expecting results in scar treatment, including burn scars. While the desire to see noticeable changes in just 2-3 sessions is completely understandable, most scar treatments are processes that require multiple sessions over a longer period than expected.
Since the recovery speed varies depending on the individual's scar severity and skin condition, continuing treatment at regular intervals determines the outcome.
Here are some points to keep in mind before starting treatment:
- The laser and intensity applied will vary depending on the depth and extent of the scar.
- It is planned as a process over several sessions, not a one-time treatment.
- Recovery speed may vary individually, so intervals are adjusted based on progress.
- It may be combined with other treatments such as scar injections rather than laser alone.
- During treatment, it is good to also take care of daily management, such as UV protection and moisturizing.
Even with old and severe burn scars, if you consult sufficiently with the medical staff and continue treatment according to the plan, you can expect an improved outcome.

Concluding remarks
Burn scars are a matter of how tissues are rearranged during the recovery process, and laser treatments, including the Pinhole Technique, approach this by re-inducing that rearrangement. There is no need to give up on treatment prematurely just because a scar is old.
To accurately determine the condition of your burn scar and which treatment is suitable, it is most accurate to confirm through direct consultation.
