What is the primary function of a chromophore in laser treatments?

The primary function of a chromophore in laser treatments is to absorb light energy. Chromophores are specific molecules or compounds within skin tissues that have the ability to absorb certain wavelengths of light emitted by lasers. This absorption leads to various effects depending on the type of chromophore and the treatment being performed.

For example, different chromophores can target melanin in hair follicles for hair removal or hemoglobin in blood vessels for vascular lesions. When the chromophore absorbs the light energy, it converts that energy into heat, leading to the destruction of the targeted tissue or the desired therapeutic effect. This principle is critical in laser therapies, as the effectiveness of the treatment largely depends on the interaction between the laser light and the chromophores present in the skin. Thus, the role of the chromophore is central to the success of laser treatments by ensuring that the laser energy is effectively utilized where it is most needed.
