The restorative advantages of red light therapy were first observed in the late 1980s, with an intriguing turn of events that inadvertently highlighted its effectiveness. NASA scientists, while working with red and blue LEDs to replicate the photosynthesis process for potato cultivation, made a noteworthy discovery: they noticed that cuts and scrapes on their hands were healing at a notably faster rate. This serendipitous observation laid the foundation for what would later evolve into a widely embraced treatment.
Today, red light therapy has transitioned into a commonly practiced procedure, found in both medi spas and home environments. “LED, or light-emitting diode therapy, is frequently combined with other complementary treatments, such as microneedling, chemical peels, or laser procedures,” explains dermatologist Bowe. “It is a noninvasive option that should not produce heat during the treatment.”
What Are the Benefits of Red Light Therapy?
Well, regular engagement with red light therapy is known to significantly alleviate inflammation, boost collagen production, and increase collagen density. This results in enhanced skin texture and a reduction in wrinkles over time. Additionally, the therapy has been researched for its applications in treating conditions like pattern hair loss and alopecia, as well as for its potential to assist in body fat reduction.
The principle behind red light therapy is its ability to facilitate collagen synthesis within the dermal layer of the skin and to mitigate inflammation. The light penetrates the skin to encourage regeneration and repair of skin cells, thereby supporting our body’s natural collagen production and skin elasticity. These advantages extend to addressing various skin concerns, including scarring, fine lines, and acne, although the latter is more commonly treated with blue light therapy.
“In clinical settings, the benefits of red light therapy are vast, encompassing skin rejuvenation aspects such as fostering collagen production, reducing fine lines and wrinkles, and managing pigmentation issues,” states Laurence Newman, Founder and CEO of CurrentBody. Furthermore, the reduction of inflammation offers additional benefits beyond mere aesthetic enhancements: when directed at specific body areas, phototherapy (often referred to as light therapy) can help alleviate pain and discomfort, promoting healing even in deeper tissues.
How Often Should You Use Red Light Therapy?
The frequency and duration of red light exposure are contingent upon the specific characteristics of your red light therapy device. “Devices used in professional settings are considerably more powerful compared to those available for personal use. Among at-home devices, those that have received FDA clearance offer a safer and more effective experience than those that have not,” Bowe advises. “For at-home therapy, it is recommended to maintain a consistent routine—aim for daily sessions or at least three to four times a week—for a minimum of six weeks to allow the device to yield optimal results.” Notably, Bowe highlights that visible skin-firming effects may take up to three months of dedicated red light therapy practice.
How Quickly Will You See Results From Red Light Therapy?
While improvements in signs of photoaging and enhanced collagen production may require a few months to manifest, red light therapy has the remarkable ability to reduce inflammation in as little as a single 10-minute session—this is the duration typically recommended by dermatologists for effective treatment.
Is Red Light Therapy Safe?
Red light therapy is widely regarded as a safe and effective treatment option suitable for all skin types. However, it is essential to observe some basic precautions. The first and foremost step is to ensure protection for your eyes by keeping them closed during the therapy sessions.
