Dermatoscopy utilizes a handheld device called a dermatoscope, which combines a magnifying lens with a light source. This tool allows for the examination of the skin at high magnification, often between 10x to 100x, depending on the device. The light source is typically polarized to reduce surface reflection, providing a clear view of subsurface structures. This capability is particularly valuable in toxicology, where subtle skin changes due to chemical exposure may be indicative of systemic toxicity.
