You’ve probably heard of the wonder-tech of red-light therapy. It is known for being able to heal and rejuvenate the skin and is a popular beauty treatment used by celebrities like Kim Kardashian, and Gwyneth Paltrow.
There are however many reasons to consider the less well known but equally beneficial — Yellow Light Therapy.
So, what exactly is yellow light therapy and what benefits should you hope to get from it?
Also known as amber light, yellow LED light therapy encompasses light with a wavelength of between 570nm and 620nm. It is known to have a shallow penetration level, making it milder than red LED light therapy. However, this penetration level also makes yellow light perfect for several skin issues.
Upon its penetration of the skin, yellow light activates several key mechanisms that change the skin’s biological pathways. Ultimately this change results in a better skin appearance.
When yellow light therapy penetrates the skin, it does so at a distance of between 0.5mm and 2mm. Immediately, the light is absorbed by the keratinocytes and melanocytes in the skin. It also comes in contact with the skin’s Langerhans and Merkel cells, which are critical to the skin’s ability to maintain its epidermidis.
The primary benefit of yellow light therapy is the stimulation of red blood cell creation. These red blood cells eventually help to improve the rejuvenation of skin cells and speed up healing for wounds and other scars.
Thanks to its shallow penetration level, yellow light can also help to alleviate several skin conditions - especially those that involve redness and uneven coloration.
Finally, yellow light can help to soothe your skin and reduce blemishes like dark spots, skin inflammation, and swelling.
With yellow LED light therapy, you may get the following benefits:
According to most sources, the most effective wavelength for yellow LED light is 590nm, such as that provided by LED Light Therapy Mask. This wavelength effectively interacts with the cells in the epidermis, thus triggering cell renewal. It also improves skin hydration and increases dermal blood flow. All in all, this wavelength can help improve your skin appearance and health.
Studies have also shown that combining LED wavelengths can be helpful. The process - which is known as polychromatic therapy - can help skin healing and even improve muscle recovery and pain relief.
Whether you're looking for a way to combat aging or have just decided that your skin isn't as healthy as it used to be, LED light therapy devices are a simple and affordable option to consider when picking out your next change.
