Acne Scars
Acne scars are among the most common long-term consequences of severe inflammatory acne, and among the hardest on a person's self-confidence. They form when deep inflammation destroys the supporting tissue beneath the skin. Collagen bundles break apart and fibrous bands develop that tether the base of the scar to deeper tissue layers; in other cases, the opposite happens and excess fibrous tissue builds up into raised (hypertrophic) scars.
Creams and serums applied to the surface cannot fix acne scars, because a scar is a change in the anatomy of the dermis and subcutis. At Haute-Derma, we build scar treatment plans on scientific principles, combining subcision, fractional energy-based resurfacing and biological repair therapies to achieve a smooth, natural-looking skin surface.
How Acne Scars Form
Acne scars result from abnormal wound healing after an inflammatory lesion:
- Tissue destruction and collagen loss (atrophic scars): When a follicle ruptures deep in the skin during severe inflammation, the surrounding collagen and hyaluronic acid are broken down. Repair is incomplete, leaving gaps in the tissue, and contracting fibrous bands pull the skin surface downward.
- Excess fibrous tissue (hypertrophic scars): In some people, the body overreacts to inflammation and fibroblasts keep proliferating. The result is scar tissue raised above the skin surface that still stays within the borders of the original lesion.
Types of Acne Scars
| Scar Type | Clinical Appearance | Characteristic Tissue Change |
|---|---|---|
| Icepick scars | Narrow, deep and sharp-edged, V-shaped and reaching down into the deep dermis. | Deeply anchored fibrous tract; small opening but very deep base. |
| Boxcar scars | Wider, with steep, well-defined edges and a flat, U-shaped base. | Broad tissue loss in the superficial or mid dermis. |
| Rolling scars | Shallow, with sloping edges that give the skin a wavy, undulating look. | Tethered by oblique fibrous bands in the deep dermis. |
| Hypertrophic scars | Raised above the skin, pink or red, most often on the chin, chest and back. | Excess fibroblast activity and collagen production during healing. |
Assessment and Diagnosis at Haute-Derma
Before planning treatment, a Haute-Derma dermatologist carries out a detailed examination:
- Mapping scar depth and fibrous bands: Identifying which scar type predominates in each area of the face (icepick, boxcar or rolling) so the right technique can be chosen for each zone.
- Checking for active inflammation: Any new inflamed acne lesions are brought fully under control before invasive scar procedures begin.
- Personalized treatment plan: Combining several methods to release tethering bands and smooth an uneven surface at the same time.
Multilayer Acne Scar Treatment
At Haute-Derma, we treat acne scars with a combination strategy:
- Releasing tethering bands (subcision): A specialized needle is used to cut the fibrous bands beneath the scar base (especially effective for rolling and boxcar scars). This releases the downward pull and creates space for new tissue to form.
- Energy-based resurfacing (fractional laser and RF microneedling): Fractional CO2 laser or fractional radiofrequency creates controlled microscopic zones of thermal injury, prompting fibroblasts to produce new collagen and elastin that fill in the scars.
- TCA CROSS technique: Reserved for deep icepick scars, this uses a controlled chemical application to rebuild the scar base.
- Biological repair therapy (PDRN / PRP mesotherapy): Micro-injections of growth factors and nutrients speed up healing, calm the skin and strengthen the extracellular matrix.
