Pinhole for Burn & Surgical Scar
The signature treatment of Yonsei Star Dermatology. Using the UltraPulse Alpha laser, we create dense micro-channels that reach the tightly tangled, hardened collagen from the surface of the skin all the way down into the deep dermis, rearranging the tissue to induce layer-by-layer regeneration.

FAQ
Common questions patients ask about this treatment.
While some may feel a slight improvement after just one session, consistency is crucial for burn scar treatment. You will experience noticeable changes, such as the scar tissue softening and the color lightening, with repeated treatments.
A 100% cure that completely removes the burn scar is difficult, but our goal is significant improvement from the current state. With a sufficient number of treatments, you can achieve over 70-80% improvement in the scar's shape, texture, and color, leading to satisfactory results.
Yes, it can be improved. Laser treatment helps to soften and loosen hardened scar tissue. As you repeat the treatments, you will feel the skin become softer and the pulling sensation gradually decrease.
Yes, that can happen. Treating a scar is like remodeling an old house. In the process of breaking down and rearranging the hard scar tissue, it may temporarily look more indented or raised. This is a natural part of the process towards a better result.
No. The 'at least one month' interval is to give your skin enough time to recover. It doesn't mean the effect is better if it's exactly one month, so you can visit according to your schedule. (However, for keloid scars, sticking to the interval is recommended.)
