Photorejuvenation is a skin treatment that uses lasers, intense pulsed light, or photodynamic therapy to treat skin conditions and remove effects of photoaging such as wrinkles, spots, and textures. The process induces controlled wounds to the skin. This prompts the skin to heal itself, by creating new cells.
Photodynamic therapy (PDT) is a form of phototherapy using nontoxic light-sensitive compounds (photosensitizers) that are exposed selectively to light at a controlled wavelength, laser intensity, and irradiation time, whereupon they generate toxic reactive oxygen species (ROS) that target malignant and other diseased cells.
To harness these wavelengths during therapy, devices “apply” red light in a non-invasive treatment that has anti-aging benefits, and helps with acne, pain management, even hair loss. Along ...
Dental infections tend to also respond better to photothermal therapy than photodynamic therapy, though both have a strong effect. [10] [11] [12] The efficacy of PDT for antimicrobial usage is limited by the properties of the membrane of the target cell such as the electrical gradient (membrane potential) and lipid composition.
