Pleural scarring

Last edited: 4/17/2026

Overview

Atrophic acne scars result from the destruction of skin tissue during inflammatory acne lesions, leading to depressions in the skin that can be categorized into icepick, boxcar, and rolling types. These scars significantly impact patients' quality of life and self-esteem 2930.

Diagnosis

  • Clinical Assessment: Identification of scar morphology (icepick, boxcar, rolling) 29.
  • Grading Systems: Use of standardized scales like the Goodman grading system for severity assessment 29.
  • Histopathology: Biopsy may be considered for atypical or complex scarring patterns 55.
  • Management

  • First-Line Treatments:
  • - Microneedling: Effective for mild to moderate scarring 5661. - Fractional CO2 Laser: Demonstrates efficacy in improving scar texture and depth 102351.
  • Adjunctive Treatments:
  • - Platelet-Rich Plasma (PRP): Combined with microneedling or laser treatments to enhance collagen production 672656. - Autologous Fat Grafting: Utilized for its filling properties in deeper scars 4. - Topical Agents: Use of insulin or hyaluronic acid in conjunction with microneedling 324.

    Special Populations

  • Pregnancy: Limited data; caution with ablative laser treatments due to potential systemic absorption [Expert opinion].
  • Pediatrics: Microneedling and non-ablative laser treatments are generally considered safe but require careful monitoring [Expert opinion].
  • Elderly: Focus on minimally invasive techniques like microneedling and fractional lasers due to reduced healing capacity [Expert opinion].
  • Comorbidities: Patients with compromised skin healing (e.g., diabetes) may benefit more from non-ablative methods to minimize risk [Expert opinion].
  • Key Recommendations

  • Use Microneedling as a First-Line Treatment for mild to moderate atrophic acne scars due to its efficacy and safety profile (Evidence: Moderate 5661).
  • Combine Fractional CO2 Laser Therapy with adjunctive treatments like PRP to enhance scar remodeling and improve outcomes (Evidence: Moderate 62651).
  • Consider Autologous Fat Grafting for deeper scars where volume restoration is crucial (Evidence: Expert opinion).
  • Select Non-Ablative Treatments for elderly patients and those with compromised skin healing to minimize complications (Evidence: Expert opinion).
  • Exercise Caution with Ablative Treatments in pregnant patients due to potential systemic effects (Evidence: Expert opinion).
