What is the main function of blue light LED therapy?

The main function of blue light LED therapy is aimed at acne reduction. Blue light has specific properties that target the bacteria responsible for acne, known as Propionibacterium acnes. By penetrating the skin, blue light can effectively kill these bacteria, leading to a decrease in inflammation and the formation of acne lesions. This therapy is particularly appealing for individuals dealing with acne-prone skin because it offers a non-invasive, drug-free approach to treating breakouts.

In contrast, improving skin hydration, reducing hyperpigmentation, and stimulating collagen production are associated with different wavelengths of light or other skincare treatments. For example, red light is typically used to stimulate collagen production and improve skin firmness. Each type of light therapy has its unique benefits depending on the specific skin concern being addressed.
