PDT System LED Beauty Machine

Photodynamic therapy (PDT) is a medical treatment that utilizes a combination of a photosensitizing agent, light, and oxygen to selectively destroy abnormal cells or microorganisms. Here's a breakdown of the principles behind a PDT system:

Photosensitizing Agent Administration: The first step in PDT involves administering a photosensitizing agent to the patient. This agent can be either administered orally, topically, or intravenously, depending on the condition being treated and the specific protocol used.

Accumulation in Target Cells: The photosensitizing agent preferentially accumulates in target cells or tissues, such as cancer cells or bacteria, due to their increased metabolic activity or specific receptors.

Activation by Light: After a sufficient amount of time has passed to allow for the photosensitizing agent to accumulate in the target cells, the affected area is exposed to light of a specific wavelength. This light activates the photosensitizing age
