What is Red Light Therapy?
Red light therapy, also known as photobiomodulation or low level light therapy (LLLT), is a treatment that utilizes red and near-infrared light to provide therapeutic benefits and improve various conditions.
How Does Red Light Therapy Work?
Red light therapy works by exposing the body to low levels of red and near-infrared light. These wavelengths of light have been found to provide numerous benefits at a cellular level by stimulating ATP (adenosine triphosphate) production and key signaling pathways.
When the light enters the skin and tissue, it interacts with cytochrome c oxidase in the cells' mitochondria. This helps increase ATP production, modulates reactive oxygen species, and activates transcription factors and signaling pathways that induce various physiological changes.
Benefits and Effects of Red Light Therapy
Some of the many researched benefits and effects of red light therapy include:
- Increased energy and reduction of fatigue
- Anti-aging effects on skin and cellular renewal
- Wound healing and tissue repair acceleration
- Joint and muscle pain relief
- Hair regrowth and prevention of balding
- Improved immunity and cellular health
- Neurological benefits and cognitive function improvement
- Enhanced testosterone and sexual health
Red Light Therapy for Skin and Anti-Aging
Red light therapy has become popular and widely used in aesthetic medicine for its many benefits in treating skin issues and promoting anti-aging effects. Some ways in which it improves skin health and appearance include:
Skin Rejuvenation and Anti-Aging
The light emitted from red light therapy penetrates deep into the skin where it stimulates collagen and elastin production. These are compounds that make the skin appear more supple, firm, and youthful. It also thickens the epidermis for smoother skin texture.
Reduction of Fine Lines, Wrinkles, and Blemishes
By increasing collagen production and cell turnover, red light therapy can significantly reduce the appearance of fine lines, wrinkles, enlarged pores, uneven skin tone, and blemishes caused by aging and sun damage over time.
Accelerating Healing of Damage and Injuries
The anti-inflammatory and tissue regenerative effects of red light therapy help heal damage caused from injuries, wounds, burns, scars, and even acne breakouts faster. This helps restore a smooth, healthy complexion.
Improving Skin Disorders
Red light therapy shows promise for improving certain skin disorders. So far, research indicates it can help with psoriasis and some mild to moderate cases of eczema and rosacea.
Red Light Therapy Devices: At-Home vs Professional Treatments
There are options for obtaining red light therapy both professionally in clinics and doing at home treatments with convenient devices.
Professional Red Light Therapy
Many aestheticians, dermatologists, chiropractors, and other specialists now offer red light therapy. Professional treatments allow for full body exposure or focused treatment of specific areas with specialized, high intensity medical devices.
While professional treatments can be very effective, especially when addressing severe issues, the sessions are relatively expensive ranging from $50-200 per treatment. And most people require 10-30 sessions or more.
At-Home Red Light Therapy Devices
At-home red light therapy devices have become very popular as an affordable and convenient way to obtain the benefits of red light therapy. Quality home devices feature medical-grade LED red light panels that allow for full body or focused facial treatments.
High end home devices provide clinical quality results when used consistently. They generally only cost $200-600 a single time fee. And many come with lifetime warranties, making them very cost effective long-term investments for improving skin and overall health.
Are There Any Risks With Red Light Therapy?
Red light therapy is non-invasive and generally considered very safe with minimal risk as long as proper protocols and intensities are utilized. That said, it helps to educate yourself on precautions and potential side effects.
UV and Heat Exposure
Most quality red light devices will only emit red and near-infrared light without harmful UV wavelengths. IR heat production from LEDs is also minimal. But heat and UV exposure risks should still be minimized by using trusted therapeutic grade devices.
Existing Health Conditions and Medications
Those with certain conditions like epilepsy and those taking medications that increase light sensitivity should check with their doctor before starting red light therapy.
Eye Damage
Red light therapy devices should never shine directly into the eyes, only into the skin. Protective eyewear should be worn as a precaution during facial treatments.
In Conclusion
Red light therapy is an emerging treatment option that shows immense promise and already has considerable scientific research supporting its many benefits. It is continuing to gain popularity and acceptance within mainstream medicine.
While more research is still needed, current evidence indicates red light therapy is a relatively affordable, convenient, and safe option for natural skin improvement and various health benefits when utilizing quality high intensity LED light devices.
FAQs
What is the difference between red light therapy and infrared therapy?
Red light therapy devices emit red light wavelengths from 630-660nm and near-infrared wavelengths from 810-850nm. Infrared therapy devices use longer infrared wavelengths from 900nm up to 1000nm. Red light therapy provides better tissue penetration for skin and cellular benefits while infrared may penetrate deeper to aid muscle and joint issues.
How often should you use a red light therapy device for best results?
Most research shows positive results with 5-10 minute sessions from a quality home device used about 3 times per week minimum. Benefits are dose dependent so optimal results come from consistent, frequent sessions either daily or every other day.
Is red light therapy safe during pregnancy?
Low level light therapy at therapeutic intensities is generally considered safe during pregnancy. But there have not been enough studies to determine absolute safety for a developing fetus. As with anything during pregnancy, discuss using red light therapy first with your doctor.
Does red light therapy help with joint pain and injuries?
Yes, a great deal of evidence shows red light effectively relieves musculoskeletal pain in joints and helps heal many different sports injuries and inflammatory conditions by modulating inflammation and speeding regeneration.
