Light emitting diode (LED) light therapy is growing in popularity in both aesthetician offices and at home. Using varying LED wavelengths, this skincare technique purportedly helps:
- treat acne
- reduce inflammation
- promote anti-aging effects
You may be a candidate for LED light therapy if you have these types of skincare concerns and haven’t gotten the results you want from over-the-counter (OTC) skin products. LED therapy is also safe for all skin colors, and it doesn’t cause any burning.
However, there are a few potential drawbacks. Here are several:
- LED therapy can be expensive.
- The results aren’t guaranteed.
- It’s also not safe if you take certain medications or have an active skin disorder.

Remember, many aestheticians recommend up to 10 sessions, so factor that total cost into your budget as you consider different practitioners and their price per visit.
Home devices cost anywhere from $25 to $250 or more. This may be a cheaper option overall because you get to keep the LED device and use it for future treatments. However, the results aren’t as dramatic.
In either case, LED light therapy is noninvasive. You don’t have to lose any money from taking time off work.
LED light therapy has an established history of skin uses. The U.S. Navy SEALs began using it in the 1990s to help heal wounds quickly and to help regenerate damaged muscle tissues.
Since then, the treatment has been researched for different situations in aesthetics. It’s mainly noted for increasing collagen and tissues. All of which can smooth out your skin and reduce the appearance of damage from:
- age spots
- acne
- wrinkles
There are different frequencies, or wavelengths, used with LED light treatment. These include red and blue light frequencies, which don’t contain ultraviolet rays and are readily absorbed into the skin.
Red light
Red, or infrared, lightis used for treating the epidermis, which is the outer layer of skin. When the light is applied to your skin, the epidermis absorbs it and then stimulates collagen proteins.
In theory, more collagen means that your skin will look smoother and fuller, which can reduce the appearance of fine lines and wrinkles. Red LED light is also thought to reduce inflammation while improving circulation, which can give you a healthier glow.
Blue light
Blue LED light therapy, on the other hand, targets the sebaceous glands, which are also called oil glands. They’re located beneath your hair follicles.
Sebaceous glands are necessary for lubricating your skin and hair so that it doesn’t dry out. However, these glands can become overactive, leading tooily skinand acne.
The theory is that blue LED light therapy can target these oil glands and make them less active. In turn, you may see fewer粉刺. Blue light can also kill acne-causing bacteria beneath the skin, which can help treat severe acne pimples, including cysts and nodules.
Oftentimes, blue LED light is used in conjunction with red LED light to:
- help treat acne
- decrease scarring
- promote anti-inflammatory effects
One
According toEstheticianEDU, each LED light therapy treatment lasts about 20 minutes. You’ll likely need up to 10 treatments total, depending on the results you’re looking to achieve.
Some providers have you lie down directly under the lights, while others use LED light-infused wands directly over your skin. The choice often depends on the office, as well as the treatment area.
Home procedures
If you can’t make it to a healthcare provider’s office, you can still try LED light therapy at home. At-home devices come in the form of masks or wands that you apply to your face for several minutes at a time. Follow the manufacturer’s instructions carefully.
While LED light therapy can technically be used on any part of the body, its most popular use is for the face. Skin damage tends to occur to your face because it’s exposed to the elements more than other body parts.
LED therapy can also be used on the neck and chest, which are other areas that tend to show signs of aging.
Overall, theAmerican Academy of Dermatologydeems this procedure safe. Since LEDs don’t contain UV rays, this is considered a safer form of light therapy that won’t cause long-term damage to your skin. The procedure is also noninvasive and has few risks.
Your provider may recommend LED light therapy if you have darker or sensitive skin. Unlike more invasive procedures such as laser therapy, LEDs don’t burn your skin. They also don’t cause any pain.
However, there may still be risks associated with LED light therapy.
If you currently use Accutane for acne, be advised that this powerful drug derived from vitamin A increases your skin’s sensitivity to light and may cause scarring in some instances.
Do not use LED light therapy if you’re using anything on your skin that makes you sensitive to sunlight.
You also might consider avoiding this treatment if you currently have an active rash. Talk with your doctor if you havepsoriasis. Red light therapy could help but only if you use it in conjunction with your regularly prescribed treatments.

In-office LED light therapy requires up to 10 sessions or more, each spaced out about a week apart. You may start to see minor results after your first session. Results will be more dramatic and noticeable once you’ve finished all of your treatments.
Even after you’ve achieved the recommended number of sessions, your results aren’t permanent.
As your skin cells turn over, you may lose some collagen and start to see signs of aging again. You may also start to see acne breakouts. This is why it’s recommended that you go back for maintenance treatments every few months or as recommended by your provider.
Home LED light therapy treatments aren’t as dramatic because the light frequencies aren’t as high. You should follow the manufacturer’s instructions.
