Light therapy devices, such as lamps and infrared devices, use very low-level light wavelengths to treat a range of minor and persistent skin complications like slow healing wounds, scars and acne, among various other issues. Back in the 90s, scientists utilised red light therapy to grow plants in space. They realised that constantly emitting red lights from diodes (LEDs) helped speed up the photosynthesis process in plant cells.

Light therapy - how does it work?

According to some scientists, red light generates a biochemical effect in the body's cells which energises the mitochondria. Mitochondria are the main source of energy that your cells need to keep functioning optimally.

How can you use light therapy?

Ever since the first red light experiments to grow plants in space, there have been a myriad of clinical studies to investigate and conclude whether or not red light therapy has adequate medicinal properties and benefits.

Although a plethora of clinical studies and research boast promising potential and results in some cases, the medical advantages of light therapy are still a bit of agrey area. However, some studies show that light therapy can be good in several ways, including:

  • Tissue repair and wound healing
  • Helps with hair growth (for people that are suffering with androgenic alopecia)
  • Helps decrease symptoms of carpal tunnel syndrome (can be used as a short-term medical intervention)
  • You can use it to treat persistent wounds such as diabetic foot ulcers
  • Helps suppress psoriasis lesions
  • Helps reduce scars
  • Helps reduce acne breakouts
  • Relieves and minimises inflammation and pain

Choosing light therapy devices

You can sift through a variety of different FDA approved light therapy devices here that are simple to use at home. From Himalayan pink salt lamps to cold laser devices and infrared ray devices, you can find a wide collection on eBay at a good price. You can even complement your light therapy device with smart speakers for some calming music.
