Where the Myth Comes From
When people hear "light therapy," they often associate it with UV lamps or tanning beds, worrying that it might darken or damage their skin. In fact, this is a common misunderstanding.
Scientific Explanation
Different spectrum used in light therapy: Common therapeutic wavelengths include red light (630–660nm) and near-infrared light (810–850nm), which contain no ultraviolet (UV) rays.
Tanning comes from UV rays: Ultraviolet light stimulates melanin production in the skin, leading to tanning. Since light therapy does not use UV light, it does not cause tanning.
Main benefits of light therapy: It stimulates cellular repair and metabolism, promotes collagen production, enhances blood circulation, and helps reduce inflammation.
Clearing Up Common Concerns
Light therapy will not darken your skin; instead, it improves skin health and radiance.
Unlike sun exposure, light therapy is non-invasive and free from risks like sunburn or photoaging.
It is suitable for daily skincare, muscle recovery, and wellness management.
Light therapy ≠ sunbathing. It does not cause tanning but instead improves skin and body health through scientifically proven mechanisms. By understanding how it works, you can use it with confidence.
