There are a number of differences between red light and near-infrared light. Firstly, while red light is visible to the human eye, near-infrared light is not. Secondly, the wavelengths of red light range from 630 to 700 nanometers, whereas near-infrared light extends notably longer, spanning from 800 to 2,500 nanometers. Importantly, red light primarily affects the skin's surface, whereas near-infrared light can penetrate approximately 30mm into the body.
Both red light and near-infrared light play crucial roles in enhancing cellular energy, reducing inflammation, stimulating collagen production, and improving blood circulation. However, red light is particularly effective for addressing skin conditions, mental health issues, promoting restful sleep, and enhancing mood. On the other hand, near-infrared light's deeper tissue penetration facilitates healing, cellular rejuvenation, and supports the health of bones, muscles, and organs.
The combination of red light and near-infrared light stimulates collagen and elastin synthesis, offering anti-aging benefits. Consequently, it's endorsed by experts as a potent remedy for sun-damaged skin. Moreover, this combination delivers safe and effective results in reducing fine lines, wrinkles, skin roughness, and increasing intradermal collagen density, leading to high patient satisfaction rates.
