Which type of light is often used in phototherapy?

LED light is commonly used in phototherapy due to its specific wavelengths and energy efficiency. In this type of therapy, different wavelengths of light can penetrate the skin at various depths, providing therapeutic effects. LED light therapy is utilized for conditions such as acne, inflammation, and various skin rejuvenation applications because it can stimulate cellular processes, improve collagen production, and enhance healing.

When considering other types of light, they do not match the specific therapeutic benefits provided by LED light. Incandescent light generates heat and lacks the specific wavelengths needed for effective phototherapy. Fluorescent light can emit a broad spectrum but is not tailored to provide the precision necessary for treating skin conditions. Sunlight, while beneficial for vitamin D synthesis, carries risks like UV damage and does not offer the controlled treatment that LED technology provides. Therefore, LED light stands out as the most suitable choice for phototherapy applications.
