Skin Photorejuvenation

Abstract

The term `photorejuvenation' describes the simultaneous improvement of various epidermal changes related to aging. Sun exposure and smoking are the main factors that induce premature skin aging. Rhytides are due to a decrease in facial skin elasticity causing accentuation of lines and wrinkles. There are three main mechanisms of non-ablative technology involved in skin rejuvenation: Heating that leads to fibroblast activation, remodeling of collagen and increased synthesis of procollagen III Dermatologic regression, represented by displacement of photodamaged dermis and improvement of epidermal and dermal parameters Endothelial disruption, cytokine activation and collagen remodeling. Hemoglobin and melanin are the primary chromophores involved in skin rejuvenation. Type I photorejuvenation refers to vascular anomalies, pigmentary changes or pilosebaceous changes, while Type II is related to dermal and subcutaneous senescence. The main advantages of IPL skin rejuvenation are minimal downtime recovery, fast and easy to perform, minimal complications, minimal interference with lifestyle and long-term improvement.
