Scar Formation & Treatment

Scar Formation & Treatment examines the biologic sequence of wound healing and the factors that determine whether tissue repair results in subtle remodeling or exaggerated fibrosis. Scarring is not merely a cosmetic outcome; it reflects a complex interplay between inflammation, collagen synthesis, mechanical tension, and genetic predisposition. As a significant procedural and regenerative focus at every global Dermatology Conference, this session explores prevention strategies, early intervention, and advanced therapeutic options for optimizing scar outcomes. Closely aligned with abnormal scar management, this field integrates surgical precision, molecular insight, and aesthetic planning.

The session begins by reviewing the phases of wound healing—hemostasis, inflammation, proliferation, and remodeling. Balanced collagen deposition restores tensile strength, yet dysregulated signaling may produce hypertrophic scars or keloids. Transforming growth factor-beta activity and fibroblast overproduction play central roles in excessive fibrosis.

Clinical differentiation between atrophic scars, hypertrophic scars, and keloids guides treatment selection. Acne scars, surgical scars, burn-related fibrosis, and traumatic injuries each present unique structural challenges. Participants will explore how tension lines, wound depth, and infection risk influence final scar appearance.

Preventive strategies emphasize proper surgical technique, tension-reducing closure, and early use of silicone gel or pressure therapy. Intralesional corticosteroids and combination chemotherapeutic injections help reduce hypertrophic thickening. Energy-based treatments, including fractional lasers and radiofrequency microneedling, stimulate collagen remodeling in atrophic scars.

Emerging regenerative therapies such as platelet-rich plasma and growth factor modulation offer promising avenues for improving scar texture and elasticity. Early intervention is highlighted as a key determinant of successful scar modulation.

Psychological impact should not be underestimated, particularly for facial or visible scars. Patient counseling and realistic expectation alignment enhance treatment satisfaction.

By integrating wound biology with innovative technology, this session equips dermatologists with comprehensive strategies for preventing excessive fibrosis and refining scar appearance across diverse clinical scenarios.
