Light therapy uses specific wavelengths of light to treat various skin conditions, including acne, aging, and inflammation. This book explains the science behind LED therapy, photodynamic therapy, and low-level light therapy (LLLT). It covers indications, device types, treatment protocols, and combination strategies with skincare products or procedures. Patient selection, contraindications, and expected results are discussed in depth. Charts and case examples illustrate clinical efficacy, providing a foundational guide for integrating light-based therapies into aesthetic practice.
