What wavelength is used by the Candela Gentle YAG for Fitzpatrick skin type 1-6?

The Candela Gentle YAG operates at a wavelength of 1064 nm, which is particularly effective for treating a wide range of skin types, including Fitzpatrick skin types 1 through 6. This longer wavelength penetrates deeper into the dermis, allowing it to effectively target structures such as hair follicles and vascular lesions in various skin types while minimizing the risk of damage to the epidermis.

The choice of 1064 nm is significant because this wavelength is highly absorbed by melanin and hemoglobin, making it versatile for applications in hair removal and vascular treatments across diverse skin tones. Additionally, the longer wavelength helps reduce the action of the laser on the superficial layers of the skin, which is crucial for achieving safe and effective treatments, especially in darker skin types that are more prone to post-inflammatory hyperpigmentation.

In contrast, the other wavelengths listed (515 nm, 640 nm, and 590 nm) correspond to different laser technologies that may have different applications or are generally not suitable for treating the full range of Fitzpatrick skin types effectively. For example, shorter wavelengths tend to be more absorbed by the epidermis, increasing the risk of side effects in darker skin types. Therefore, the choice of 1064 nm for the Candela Gentle
