On a Fitzpatrick classification of V (5), which wavelength is suitable for use?

In the Fitzpatrick classification system, skin type V is characterized by darker skin tones that typically tan easily, but may not always respond well to certain laser treatments due to their melanin content. For individuals with skin type V, the 1064 nm wavelength is ideally suited for laser treatments. This is primarily due to its deeper penetration into the skin while minimizing the risk of epidermal damage, which is a critical consideration when working with darker skin types that have a higher chance of hyperpigmentation.

The 1064 nm wavelength is part of the Near Infrared range, making it effective for targeting hair follicles without dramatically affecting the surrounding skin. This depth of penetration allows for effective hair removal while reducing the risk of adverse effects associated with higher wavelengths that may affect the epidermis more directly.

In contrast, other wavelengths like 755 nm, 810 nm, and 532 nm might not be appropriate for Fitzpatrick V skin due to their potential for causing burns or pigmentation changes. The 755 nm and 810 nm wavelengths are typically more suited for lighter skin types, and 532 nm is even less suitable for darker skin due to its higher absorption by melanin, which could lead to skin damage. Thus, the use of 1064 nm for
