BonBoZ: Atrophic Acne Scar Treatment Begins with Understanding Scar Architecture

Phụ Nữ Việt Nam Online published an article on October 14, 2026, regarding BonBoz Clinic’s approach to atrophic scar treatment: Dr. Kim Kha, MSc, Specialist Level I identifies scar structures, evaluates the skin foundation, and clarifies improvement goals prior to considering any modalities. The core takeaway is that no single technology is suitable for every atrophic scar case.

Three scar structures that must be distinguished

The article distinguishes three common types: ice pick scars with narrow openings that extend deep; boxcar scars with well-defined edges; and rolling scars, which are often tethered by fibrous bands pulling the skin surface down. An individual may present with multiple scar types concurrently; therefore, merely assessing the overall surface unevenness is insufficient for developing a treatment plan. BonBoz further elaborates on this scenario in the article three types of atrophic scars on a single face.

Modality follows evaluation, not precedes it

Depending on the lesion characteristics, the physician may consider TCA CROSS for certain ice pick scars, subcision when fibrous tethering bands are present, or fractional CO2 laser and RF microneedling in appropriate cases. These are options that must be evaluated on an individualized basis, not a list of techniques to be self-applied at home.

Phụ Nữ Việt Nam Online also clearly emphasized that these techniques are invasive and must be performed by a physician at a licensed facility. Performing DIY TCA application or microneedling at home can lead to further tissue damage and pigmentary disorders.

A plan with structured reassessment steps

At BonBoz, the treatment plan is outlined in four steps: assessment, targeting the exact anatomical structure, regeneration, and recovery. The skin is reassessed after each phase, allowing the physician to adjust the approach as needed rather than relying on a predetermined, rigid protocol for everyone.

The realistic objective is to improve scar depth, surface smoothness, and skin quality within the physiological limitations of each individual condition—not a guarantee of complete scar eradication. The degree of improvement also depends on scar type, skin foundation, chosen modality, individual biological response, and post-treatment aftercare.

Those considering treatment can review the atrophic scar consultation protocol at BonBoz before submitting their case for evaluation.
