What is the purpose of using LED lights in skin treatments?

Using LED lights in skin treatments serves the primary purpose of stimulating cellular activity. This process occurs because different wavelengths of light emitted by LEDs penetrate the skin at varying depths, promoting various biological responses. For instance, red light is known to enhance circulation, boost collagen production, and accelerate healing by stimulating fibroblasts, which are essential for skin repair and regeneration.

This stimulation encourages the skin cells to function optimally, leading to improved texture, tone, and overall appearance of the skin. Additionally, LED therapy can help reduce inflammation and target issues such as acne and signs of aging, further substantiating its role in enhancing cellular activity.

While heating the skin can also affect certain skin treatments, it is not the main function of LED light therapy. Vaporizing impurities is more associated with steam or other cleansing techniques, and moisturizing the skin is typically achieved through topical products rather than light therapy. Therefore, the correct answer highlights the unique and effective mechanism through which LED lights facilitate skin rejuvenation and health.
