If you care about your skin, there is a big chance that you have heard about RLT or Red-Light Therapy. It is a therapeutic treatment procedure that uses red Light-Emitting Diodes to produce low-level wavelengths that can penetrate the skin in a non-invasive manner.
The mitochondria in the skin cells will absorb the red light to generate energy, which medical experts believe can help with cells’ repair and health. However, this kind of procedure has a wide range of applications, from pain relief, dental, skin, and beauty care.
But most people are interested in its anti-aging application. Today, it is a lot easier to use RLT at home, thanks to newly designed portable Light-emitting diode devices available in the market. Whether people owned a device already or they want to check out the technology before they buy one, here is everything people need to know about RLT for beauty.
What is RLT?
Red-light Therapy or RLT uses light-emitting diode or LED to produce minimally invasive light wavelengths to promote cell growth and treat various health conditions. Light-emitting diodes use semiconductor chips that are composed of diodes situated on a surface to produce a bright light. How the semiconductor is composed will determine the colors and wavelengths of the light.

These semiconductors can produce red, yellow, or blue-colored lights, even infrared. Different colors or wavelengths of light penetrate the different depths of our skin. Red light is in the spectrum of 630 to 700 nanometers, making it pretty effective for treating wrinkles and other aging signs.
Light-Emitting Diodes or LEDs create less heat compared to regular light bulbs. Because of its lower temperature, LED therapy devices can be used regularly and comfortably on people’s bodies. RLT devices usually produce visible light that people can see and infrared wavelengths that are in the non-visible spectrum.
When the LED technology started in the 1960s, the National Aeronautics and Space Administration in the 90s were the first to use narrow light wavelengths for clinical or medical applications. Today, this technology has different consumer and clinical uses. People may also hear of its other names – LLLT or low-level laser therapy, LPLT or low-power laser therapy, and PBM or photo bio modulation. The most common use of these devices is for anti-aging therapy.
How does RLT work below the skin?
Although red Light-Emitting Diode doesn’t feel hot to the touch, they generate heat and friction below the skin surface. Energizing the cell this way increases its activity and causes them to reproduce a lot faster. Our cells take in energy via the mitochondria, which tells them it is time to undergo cell division.
Using RLT is like boosting the metabolism of the skin cell. Every time the skin cell splits using the red LED’s energy, it generates two copies of itself. As these new cells emerge, they replace old and damaged cells contributing to the skin’s aging.
This treatment is more healthy cells, which can help contribute to a more youthful appearance of the skin. RLT can also improve blood circulation to help bring more nutrients and oxygen to the skin’s surface. Improved blood flow also helps to faster cell regeneration. Unlike abrasion or laser therapy, RLT does not need to destroy the skin tissue in order to restore it. Instead, this minimally invasive procedure boosts the skin’s cellular regeneration.
Uses in Anti-aging treatment
A lot of the more popular benefits of RLT involve treating signs of aging; RLT has been shown to reduce the appearance of:
Dark spots
Crow’s feet
Wrinkles
Not only that, but the energy from red light may also help with the wound-healing process, as well as reducing the appearance of scars. When it is used with blue lights, RL may also help minimize blemishes and acne. Other applications for RLT include regenerating gum tissues, muscle tissues, and other parts of our body.
Does it have side effects?
This treatment is usually deemed safe when using this therapy in and Food and Drug Administration-cleared home devices or in dermatologist’s offices. Infrared and red LEDs contain Ultraviolet rays, so there are no skin cancer risk people get from the sun.
Too much exposure to LED could potentially cause eye damage or burns. Please, always follow the manufacturer’s instructions to avoid any side effects from overdoing the treatment. It is advisable to consult with medical professionals or dermatologists before starting a new treatment to avoid any individual risk factors.
How long does it take to work?
Like most skincare or beauty products, its effects take time. Every device comes with a recommended usage time, traditionally from three to ten minutes per area. People can go once or twice a day. Others choose to do it every other day, as their schedule allows them. To get a good result, users need to be consistent with the treatment. Even so, appearance and skin tone improvement will happen step by step or gradually.
People may see minor effect quickly, but they will continue to see its full effects for more or less three months. After that, people will want to use it less frequently for aftercare or maintenance. To learn more about red light therapy, make sure to check out studies conducted by professionals or talk to a dermatologist for more information.
It is best if people track their results with a before and after picture. Once they have their new device, take a picture every day for a week with the same position, and check the results week after week. It is also very important to use the device correctly to see the best result.
What devices are available for beauty care?
These devices had come a long way from when the National Aeronautics and Space Administration first used them for its clinical purposes. Now, the public can purchase it to perform RLT at the comfort of their home. Finding the right device still depends on the size of their device and the range of applications.
Portable devices that help wrinkle reduction can be easily stored in bags or purses for instant wrinkle treatment, while larger portable panels can help treat a large part of the neck, back, and face on single treatments. Explore these anti-aging devices to get glowing, beautiful, and healthier skin.
