What is the term for the target that absorbs laser energy?

The correct term for the substance or component that absorbs laser energy is "chromophore." Chromophores are specific molecules or structures that have the ability to absorb particular wavelengths of light. In the context of laser treatments, the chromophores can be found in various skin components, such as melanin in hair and skin, hemoglobin in blood vessels, and water in tissues. When a laser is applied, the chromophore absorbs the energy, which can then lead to effects such as heat generation, coagulation, or tissue disruption, depending on the treatment and goals of the procedure.

Understanding the role of chromophores is critical in esthetic practices, as it enables practitioners to select the appropriate laser wavelength and settings for targeting specific skin conditions or structures. In contrast, the other terms mentioned, such as photoreceptor, thermophore, and transducer, refer to different concepts that do not specifically define the target that absorbs laser energy in the context of esthetic procedures.
