What range do UVA rays fall within in terms of wavelength?

UVA rays are classified as a type of ultraviolet radiation with wavelengths ranging from 320 to 400 nanometers (nm). This range is significant because UVA rays are known for their ability to penetrate the skin more deeply compared to UVB rays, which have shorter wavelengths. UVA rays are primarily associated with skin aging and can contribute to the development of skin cancers. Understanding the wavelength range is crucial for electrologists and skincare professionals, as it helps in selecting appropriate protective measures and treatments for clients' skin types when dealing with hair removal and other skin care services. The other wavelength ranges correspond to different types of UV radiation; specifically, UVB radiation falls within 280-320 nm, while UVC radiation is found in the 100-280 nm range, and visible light extends from 400-700 nm. Each of these ranges has distinct characteristics and biological effects, making it essential to accurately identify UVA rays.
