Approach of Sae Sal Laser (Pinhole Therapy) for Hypertrophic Scars

Scars are difficult to improve with simple laser application alone.

Sae Sal Laser is a delicate procedure customized to the characteristics of each scar.

1. CO₂ and Er:YAG Lasers: Appropriate Selection for Each Area

For wide and firm scars, CO₂ laser can be used to provide effective stimulation.

For relatively thin or sensitive areas, Er:YAG laser allows for precise treatment.

The medical team directly determines the type of laser, considering the individual characteristics of the treatment area.

2. Adjusting Pinhole Spacing and Size

In most cases, the procedure is performed with a spacing of 1 to 2mm.

However, depending on the scar's appearance, the spacing can be widened to 3mm or more, or applied more densely.

The medical team directly evaluates the scar's location, shape, and thickness to adjust the appropriate spacing and depth.

3. Precise Design of Ablation Depth (Upper or Lower Dermis)

During the procedure, we determine how shallow or deep the laser should be applied.

Stimulation can be applied only to the upper layer of the dermis,

or, in some cases, the procedure can access the collagen layer of the lower dermis.

This treatment range is individually set based on the medical team's professional judgment.

Such precise adjustments are possible only with extensive experience and know-how.

4. Direct Procedure by the Medical Team, Not Automated Treatment

The medical team directly establishes the treatment plan through consultation.

We meticulously check the condition of the lesion,

carefully design the pinhole's position and spacing for each scar,

and delicately adjust the laser intensity according to the patient's individual skin condition.

We also continuously monitor the recovery process after the procedure,

and inform you about the need for additional procedures and appropriate intervals.

What is Sae Sal Laser (Pinhole Therapy) for Hypertrophic Scars?

Sae Sal Laser (Pinhole Therapy)

uses a CO₂ or Er:YAG laser to create microscopic channels spaced 1-3mm apart within hypertrophic scars that protrude above the skin. This breaks the connections of excessively proliferated collagen tissue,

and is a procedure that helps relax the tense structure of the scar, allowing its volume to naturally reduce.

This procedure is characterized by deeper penetration than general skin surface treatments. It is not merely a method of shaving off the surface, but rather accesses deep into the dermis, making it suitable for improving papular and hypertrophic scars.
