What effect does laser energy have on melanin?

Laser energy specifically targets melanin, which is the pigment responsible for the color of skin, hair, and eyes. The technology employed in laser treatments, such as selective photothermolysis, uses specific wavelengths of light that are absorbed by melanin. When the laser energy is applied, it is absorbed by the melanin, causing it to heat up and break down. This breakdown leads to reduced pigmentation in areas of hyperpigmentation or unwanted hair, making laser treatments effective for conditions like melasma, age spots, and for hair removal.

Understanding this interaction is crucial in clinical practice as it informs both the approach to various skin types and conditions affected by melanin. Each treatment can be tailored based on the individual's skin characteristics, maximizing efficacy while minimizing damage to surrounding tissues.
