What is the wavelength that is considered best for skin types 4-6?

• A. 800 NM
• B. 1064 NM
• C. 980 NM
• D. 300 NM

Answer: (B)

The wavelength of 1064 NM is considered optimal for treating skin types 4-6, which include individuals with darker skin tones. This is primarily due to the wavelength's deeper penetration capability into the dermis while minimizing absorption by the melanin in the epidermis. Longer wavelengths, such as 1064 NM, are less absorbed by the pigment in the skin, reducing the risk of hyperpigmentation or other adverse effects. This makes it suitable for therapies like laser hair removal or other aesthetic procedures on darker skin types. The choice of 1064 NM wavelength allows for effective targeting of deeper structures such as hair follicles without damaging the surface layers of the skin, which is crucial for maintaining the integrity and appearance of the skin in higher Fitzpatrick skin types. In contrast, shorter wavelengths might be absorbed more significantly by the melanin, increasing the risk of side effects and making them less suitable for individuals with darker skin tones.
