What is the measurement in nanometers for the blood-specific photofacial filter used in Fitz 1-5?

The blood-specific photofacial filter used for Fitzpatrick skin types I to V typically operates around 615 nm. This wavelength is optimal for targeting hemoglobin in the blood, making it particularly effective for treating vascular lesions, such as spider veins and rosacea, which are often more pronounced in these skin types.

By using a filter that is specifically tuned to this wavelength, practitioners can achieve better results in reducing unwanted red pigmentation while minimizing potential damage to surrounding healthy tissue. The choice of 615 nm as the effective wavelength reflects a deep understanding of how light interacts with blood and its components, thus providing a tailored approach for skin rejuvenation in individuals with varying degrees of pigmentation.
