LED Light Therapy What Is It, And Does It Work? | Woburn, MA & Dover, NH | Age Less Weigh Less

Technology and skincare routines continue to intersect. Before, you would have to try out surgical procedures to experience the wonders of technology on your skin. But these days, you can do your skincare routine with technology without resorting to surgical procedures, and an example of this is LED light therapy

LED light therapy is the new trendy aesthetic treatment in the block, promising the allure of fixing a long list of skin blemishes, including acne scars, fine lines, wrinkles, and inflammation. While it does claim and promise many things, the therapy does, in fact, live up to its claims. You can simply try this new treatment by reaching out to a medspa or an aesthetic clinic. 

But what is the treatment exactly, and how does it work? We will explore these questions and get to the bottom of them. We want you to be as informed as possible to know if you need the treatment or not. 

What Is LED Light Therapy?

LED light therapy is a proven non-invasive treatment that uses diverse light wavelengths of infrared light to help address various skin blemishes such as acne, wrinkles, fine lines, and acne scars. The treatment wasn’t intended for aesthetic purposes but for scientific applications. NASA initially developed this technology for plant growth experiments in shuttle missions. 

Later on, NASA scientists discovered that LED light has potential applications for wound treatment. Now, LED light therapy is a commonplace treatment offered by many aestheticians to rejuvenate the skin and reduce signs of aging. Even to this day, research on this topic continues and grows, opening more potential applications in the future. 

Without a doubt, light affects your skin in one way or another. Especially true for light energy in high-energy forms such as lasers and IPL treatments. Even the light from the skin affects your skin molecules, altering the biological activity within your skin. 

Benefits Anyone

Regardless of your skin color, type, and ethnicity, you can use the treatment to enhance your skin. The treatment literally involves shining a light wavelength on you, so there’s no harm done to your skin. If you aren’t sure about it, check some reviews and before and after photos of some patients. They can tell you the whole story of their experience. 

However, if you are experiencing certain skin conditions, you should consult with a doctor first. They can tell you if you are applying for the treatment or not. 

Quick And Easy

LED light therapy is a quick in-and-out aesthetic procedure. It’s non-invasive and safe, with the bonus of being able to treat several skin blemishes at once. The treatment will only take around 20 minutes or so, and after that, you can go on to your merry way without any downtime. 

While the procedure is easy, seeing the results from the therapy will take patience. The biological process in your skin won’t happen overnight. But once you’ve undergone all the sessions and some time passes, you will see that your skin drastically changes for the better. 

How Does It Work? 

LED light therapy uses light wavelengths to clear blemishes and reveal an even, radiant, and natural-looking skin complexion. As the name suggests, it uses light-emitting diodes to emit these wavelengths. The wavelengths in the visible light spectrum can penetrate the skin at various depths, stimulating biological activity in the skin. 

Different wavelengths are a crucial part of the procedure, and they are the ones responsible for rejuvenating the skin. This means that changing the light wavelengths can produce different outcomes on your skin. However, these light wavelengths are not ultraviolet lights, so rest assured that they are not cancerous. 

Different Light Wavelengths

Many light wavelengths are applicable for your skin therapy, but the most popular ones are red and blue wavelengths. Other options exist, such as yellow and green. While they are not well-studied, they are often used in skin therapies. Here is how each one of these treatments works:

Red Light

Studies have shown that a specific red light wavelength can stimulate collagen production, reduce inflammation, and increase blood circulation. So naturally, this wavelength is used for treating fine lines and wrinkles. This wavelength also helps you achieve a more even skin tone and an overall brighter complexion. 

Thanks to its healing and rejuvenating properties, the red wavelength is often used as an add-on therapy for other procedures such as lasers, chemical peels, or microneedling. The therapy decreases recovery downtime by accelerating the skin’s healing properties. Also, red light wavelength lessens the risks of side effects such as redness, bruising, and swelling. 

Red light therapy also helps ease inflammation like psoriasis and rosacea. 

Blue Light

On the other hand, blue light therapy penetrates your sebaceous glands, also called oil glands. These glands are located just beneath your hair follicles. They are necessary to protect your skin, lubricating the hair and the skin so it doesn’t dry out. 

However, these glands tend to be overactive and become a suitable environment hotbed for different bacterias. These bacteria then react, causing acne breakouts all over your skin. Fortunately, blue light can penetrate this skin layer and affect it. 

Blue light wavelength targets these oil glands and makes them lesser active. On top of that, the blue light also actively kills the acne-causing bacteria, treating severe acne breakouts, including nodules and cysts. 

Yellow Light

As stated earlier, there aren’t many studies regarding yellow light. While there are no concrete studies, some have observed yellow light as effective in reducing redness and healing time. This is thanks to its ability to penetrate deeper into the skin, even more so than red and blue light. 

Research has also demonstrated that yellow light can supplement red light in treating fine lines and wrinkles. 

Green Light

Likewise, isn’t also in-depth studies about the green light. However, a few have observed its ability to reduce aging signs by stimulating collagen growth underneath the skin.
