Fractional CO2 laser Combined with TCA for the Treatment of Keloid Scars

Abstract

Scarring is a complex phenomenon , Following an injury to the skin, whether voluntary or post-surgical, the healing process begins. This is a long physiological process designed to restore the integrity of the skin covering [1]. In certain circumstances, ad integrum restitution cannot be achieved, leading to pathological scarring. Risk factors can be local, depending on the topography of the lesion, or general, depending on age or genetic predisposition. We distinguish two types of pathological scars: hypertrophic and keloid [2]. Indeed, it has been confirmed that the latter are the cause of serious psychological problems, as they are not only aesthetically embarrassing, but also lead to an alteration in patients' quality of life and self-esteem [3]. The therapeutic arsenal is broad, and includes corticosteroids in intra-lesional and topical injections, pressotherapy, surgery, radiotherapy, cryotherapy, 5-fluorouracil (5-FU) and lasers [4]
