Which type of light rays are used in a salon to heat and relax the skin?

Infrared rays are used in salons to heat and relax the skin because they penetrate deeper into the tissues compared to other types of light. This deep penetration allows for soothing warmth, which helps to increase blood circulation and promotes relaxation of the muscles. Not only does this lead to a feeling of comfort, but it can also enhance the effectiveness of various treatments by preparing the skin, increasing its elasticity, and facilitating better absorption of topical products.

In contrast, ultraviolet rays are mainly associated with skin tanning and damage, while X-rays are used primarily in medical contexts for imaging and not for skin treatments. Visible light, while essential in various applications, does not provide the specific heating effect beneficial for relaxation and skin treatment that infrared rays do. Thus, infrared rays are the ideal choice for promoting relaxation and warmth in a salon setting.
