How do laser wavelengths differ between types of skin?

Different wavelengths of laser light interact with the skin in various ways, making their effects highly specific to different skin types and conditions. Each wavelength can be absorbed by different chromophores in the skin—such as melanin, hemoglobin, or water—leading to varying treatment outcomes. For instance, darker skin tones with more melanin may require specific wavelengths to ensure effective treatment while minimizing damage to surrounding tissues. This specificity allows practitioners to select appropriate laser settings to target particular issues like hair removal, pigmentation, or vascular lesions while considering the patient's skin type. The choice of wavelength is crucial for achieving optimal results and reducing the risk of side effects, especially in diverse patient populations.
