August 08, 2023 (IANSlife) LED light therapy, also known as phototherapy or low-level light therapy (LLLT), is a non-invasive medical procedure that utilizes specific light wavelengths to stimulate cellular function and support the healing process. By exposing the skin to different colors of LED light, various therapeutic effects can be achieved.
The main colors used in LED light therapy are red, blue, yellow, and near-infrared (NIR), each offering distinct benefits:
LED light therapy is generally regarded as safe and painless, without involving any UV radiation, making it suitable for all skin types. It is commonly used in dermatology clinics, medical spas, and home-based devices. The duration of treatment sessions varies but is typically short, ranging from a few minutes to half an hour, depending on the specific condition being addressed and the LED device used.
Potential benefits of LED light therapy include:
While portable LED light therapy devices in the form of masks, panels, and wands are now available, the LED Light Therapy machines found in a doctor's clinic may be considered more efficient for several reasons. Clinics' devices often have a higher number of bulbs, covering a larger surface area with more sophisticated technology. Moreover, LED Light Therapy is not a skincare tool to be used casually; different colors address specific concerns, and a professional diagnosis is best for determining the appropriate treatment.
