LED Therapy Light: What is it and how does it work?
LED Therapy light is a popular skincare technique used by people all around the globe. But what is it? And should you try it?
Light-emitting diode (LED) therapy is a non-invasive way to treat your skin, as it uses light wavelengths which include red and blue light waves. Although originally developed by NASA, it has become a popular way for people to take care of their skin. The treatment can be administered by professional aestheticians as well as an at-home DIY treatment. In short, it is believed to be a regenerating therapy to prevent the signs of aging as well as treating acne.
Originally, the scientists at NASA used LED technology on experiments for plant growth on shuttle missions before it was discovered for its wound treatment ability. Typically, your aesthetician will evaluate the condition of your skin and use either blue or red light to treat your skin. The red frequency is generally used to prevent the signs of aging while blue light is considered best for treating acne.
What is LED Therapy Light?
The LED therapy uses non-thermal light-emitting diodes to kick start the body’s internal cell processes. Because all it does is trigger your cell’s natural processes, the LED therapy helps your body to heal itself. Excessive sun damage, inflammation, and aging are often treated using LED therapy.
How Much Does it Cost?
Although the cost can range, you can bank on between $25 and $85. The cost will be dependent on where you live (and where you go for the treatment) and the other accompanying therapies. Many people are choosing to do this therapy from home and purchase a home LED kit. This can save money in the long term and the home kits can range from $25 to $250, depending on the kit purchased.
Does it Work?
According to your local dermatologist, yes, LED light therapy can be an effective rejuvenating treatment for your skin. And there is research to back this up, too. Whether you want it for wound healing or to get back that glow, LED light therapy is a good way to go.
Did You Know?
Navy SEALs used LED light therapy to treat wounds, reducing the time it took for wounds to heal and the therapy helped a minimum of 40% of musculoskeletal injuries.
This review of several case studies indicates that LED therapy can be an effective treatment for an assortment of skin disorders, including psoriasis and acne. The American Academy of Dermatology states that the majority of people that try LED therapy for acne can expect improvements.
So, why the confusion? There seem to be many people wondering whether it works, despite the evidence. This could be because it is not a one-hit-wonder- there needs to be consistent application and follow-up sessions before you can see improvements. In many cases, the results are only evident several weeks following the final LED session.

What are The Different Colors of Led Light and What Do They Do?
If you want to understand a bit more about the different LED colors, here is a more detailed breakdown of the different LED light options. Use this guide to help you select which light to opt for. If you are still unsure, your esthetician should be able to provide you with guidance after an evaluation of your skin.
LED lights have seven distinct colors for therapy:
Red Light (650nm).
If you are looking to promote collagen production and stimulate blood flow, red could be the way to go. Because it is so stimulating, red light is often used to counter aging and sun damage. Rosacea and some types of acne can benefit from the red LED light.
Blue Light helps to target specific issues such as progressive acne, inflammation, and aging in particular. The blue light is often used to tighten tired skin to promote a more youthful appearance.
Green light is often used for people seeking anti-aging therapy. The green LED light is famous for reducing pigmentation and reviving loose skin and encourages supple skin.
Yellow light is often used to relieve inflammation, redness, irritation, and even rosacea. The yellow light is used to promote a smooth complexion. People using an at-home device often use yellow light as it is well known as a gentle color for beginners.
Purple LED light is used to promote relaxation and relieve stress. It is also beneficial for lymph metabolism.
Light blue (510nm).
Another calming color, light blue is a gentle LED light for people that have extreme sensitivities, particularly to sunburn and inflammation. Blue LED light therapy is a popular treatment for seasonal allergies.
White Light (470nm)
White light is a newer LED color and is best for people that suffer from a wide range of issues. If you are unsure which of the above categories you fit into, then White LED therapy may be the best choice. White Light is effective for acne, inflammation, wrinkles, rosacea, healing wounds, and could even breathe new life into damaged cells. Research indicates white LED light can assist with regulating mood and sleep too. And that’s not all, white LED light could be a helpful stimulant for tissue metabolism- which in turn coaxes your skin to appear healthier at a more rapid rate.
How to Prepare for LED Therapy Light
The golden rule is to remove all makeup and impurities. This is for both an in-office machine as well as a home mask or wand. Use a cleanser that is gentle on the skin to avoid irritation. Remember to use your safety goggles to shield your eyes from the light.
What to Expect after the Therapy
Aftercare for your skin following the therapy is essential, however, you won’t need recovery time as the LED therapy is a non-invasive treatment. You can go about your day straight away after the session. While you might want to see results immediately, remember that is unlikely. There may be some minor results visible but it will take a few sessions until you see any visible results. Some people often experience their desired results only after the final session.
LED therapy is a non-invasive treatment and is considered safe for most skin types. While there are rare cases of side effects, some people report inflammation or skin redness following therapy. If you are taking any oral medication, especially if it is for acne, you may want to have a chat with your doctor as these medications can increase your skin’s sensitivity.
As for a safety precaution- please remember to use safety goggles or an eye mask to protect your eyes.
How to Use Led Light Therapy at Home
LED light therapy devices are simple and easy to use at home
Do Home Devices Work?
Home devices are great for maintaining results and giving your skin a healthy boost. However, they are not as effective as the treatments you will receive from an in-office professional. Home devices are recommended for mild cases, or for simple rejuvenation and healthy skin.
Follow this step by step guide for using LED Light Therapy at home:
1.Read the Instructions
We’re not joking, it is essential to follow the manufacturer’s guidelines throughout the session.
2. Cleanse your skin
Remove any make-up and give your face a good cleanse, removing any impurities that may inhibit the LED therapy. There are several specifically formulated creams to apply before the therapy. These are optional but they could enhance the overall effects.
3. Select the LED light color
Use the LED Light color guide to help you select the color for your therapy.
4. Set Treatment Time and Intensity
Set the desired amount of time and intensity on the device. The typical session lasts between 20 and 30 minutes.
5. Set up your Mask
If you are using a mask instead of a handheld device, then get comfortable and make sure you have cotton wool or a eye mask to protect your eyes. Using a LED mask is one of the most relaxing ways to use at-home LED therapy. All you have to do is prep your skin, lay back, and enjoy the relaxing session.
6. Facial Wand Prep
If you are using a facial wand, you should always use protective eyewear to ensure you are protecting your eyes. Holding the wand, move it in a slow-motion across your face. Begin by the mouth’s corner and slowly move it towards your eyes. Move back down to your chin and slowly move it towards your ear lobes and back to the corner of your mouth. Read the manufacturer’s instructions for their recommendation on the correct distance.
At-Home vs. In-Office LED Light Therapy
While both have their advantages, there are a few defining points that could be the deciding factor on whether you choose to do at-home or in-office therapy.
If you have severe issues that you would like to treat, then booking your sessions through in-office treatments is the best way to go. But even then, buying an at-home LED therapy mask will be beneficial. LED therapy is most beneficial when followed up with continuous sessions. The at-home LED devices are easy to use and are always available for you to use whenever suits you best.
What’s more, using an at-home device can bolster your in-office treatments too. You can give your skin incremental benefits and maintain the results of the in-office therapy sessions.
At the end of the day, the at-home devices are an excellent investment for your skincare routine as well as your overall sense of wellness.
