What is the wavelength range for cosmetic monochromatic light?

• A. 200 nm - 400 nm
• B. 400 nm - 800 nm
• C. 400 nm - 10,600 nm
• D. 10,600 nm - 20,000 nm

Answer: (C)

The correct wavelength range for cosmetic monochromatic light is 400 nm - 10,600 nm. This range encompasses a broad spectrum of light that includes visible light and extends into the near-infrared region. In cosmetics and esthetics, various light therapies utilize wavelengths within this range for different skin treatment goals. For example, visible light (approximately 400 nm to 700 nm) is commonly used for skin rejuvenation, while the near-infrared portion (700 nm to 1,000 nm) can penetrate deeper into the skin, providing benefits such as increased collagen production and improved circulation. The larger range up to 10,600 nm includes not only visible and near-infrared light but also wavelengths used in certain advanced treatments, such as laser therapies, which can target specific skin concerns effectively. This understanding of light's wavelength ranges is crucial for estheticians when selecting appropriate technologies and modalities for client treatments.
