Which type of light rays are estheticians primarily concerned with?

Estheticians primarily focus on infrared rays, ultraviolet rays, and visible light because these types of light are fundamental to various skincare treatments and procedures.

Infrared rays are often used for their heating properties, which can help increase blood circulation and enhance product absorption during treatments. Ultraviolet rays are crucial in understanding the effects of sun exposure on skin, as they can lead to various skin conditions and aging; shielding the skin from harmful UV rays is a key aspect of esthetics. Visible light is significant not only for its use in various devices like LED therapy masks but also for understanding the natural impacts of light on skin health and appearance.

In contrast, other types of rays such as X-rays and gamma rays fall outside the scope of typical esthetic practices, as they are primarily used in medical settings. Radio waves and microwaves are more associated with telecommunications and cooking, respectively, rather than skincare applications. Laser beams and neon light also play roles in esthetics, yet they are specific technologies or effects rather than foundational types of light that estheticians must regularly evaluate and utilize in their practice.
