What Is It: Lightwave LED treatment

Reviewed by Marta April 1, 2008 15 Comments

Today I visited my esthetician, Ildi Pekar, for my usual microdermabrasion and microcurrent session. Only this time, I followed it up with a 30-minute treatment for wrinkles and hyperpigmentation using LED light therapy. It was a great experience: completely safe and comfortable with immediate visible results. I'll come back to the results after explaining how it works.

LED is light emitting diode with a low-level power output that uses red light (visible) and infra-red light (invisible). LED is much gentler than intense pulse light (IPL) or laser resurfacing. It works by stimulating the body's tissues to convert the light energy into cellular energy. It boosts collagen production and scavenger cells that remove excess pigmentation or scar tissue.

In Europe, LED has been used for about 50 years to treat muscular pain, scars and wounds. It came to be used in the US relatively recently in the 1980s.

The machine Ildi uses is called Lightwave. It seems to be very flexible, with multiple settings depending on whether the therapy is, for example, for wrinkles or age spots. I had simultaneous treatments on my face, decollete and hands. The red light is extremely bright (you wear goggles) and lasts for four minutes, followed by the infra-red light, which is just blackness. This is repeated four times. It feels slightly, agreeably warm.

The effects are interesting. The first thing I did was look in the mirror. I looked as if I'd been on a spa vacation - all luminous and rested. I then noticed that I was extremely thirsty; lymphatic drainage is increased by the treatment. About an hour later, it occurred to me that my mood was noticeably improved; one of the other (good) side-effects is that the endorphins are stimulated.

Two and half hours after the treatment, I still look rested and my skin feels incredibly firm. My freckles are notably darker (I've been told that IPL makes dark spots darker before they disappear, so this may be a similar process) and I am a bit pink at the neck. It will be interesting to see what I look like in a couple of days and, of course, after the full six to eight treatments recommended.

UPDATE: In October 2008, German researchers identified how the visible light works — by changing the molecular structure of a glue-like layer of water on elastin, the protein that provides elasticity in skin, blood vessels, heart and other body structures. The light strips away those water molecules that are involved in the immobilization of elastin, gradually restoring its elastic function and thus reducing facial wrinkles. "We are justified in believing that our approach can be easily converted to deep body rejuvenation programs," the researchers state.

    Hi Carolyn, I'm a bit confused about NuLase. They call it "soft laser light". I don't know what that is, but its not LED. Their website is very vague about the technology.

    Hi Marta,

    Do you know anything about NuLase? I purchased this a few years ago but I gave up on it because it didn't seem to be doing anything. There is a small red light at the end of the wand that I think they claim is an infrared light.
    Thank you.

    Hi Martha,

    If anyone is looking for a great place to get light therapy, please feel free to have them visit our locator page at All our providers do an excellent job at administering light therapy.

    I have also been a certified trainer for LIGHTWAVE for the past 6 years and can tell you that there is definitely a big difference between LED delivery systems. In order for light therapy to work it must be powerful enough and have a long enough exposure time or dose to deliver photon energy into the body especially since LED is scattered light particles. It also needs to be the correct wavelengths so the cells absorb the photon energy instead of reflecting it or allowing it to pass right through. The delivery system can make all the difference between no results and great results. LED light therapy works wonderfully if administered correctly.
    It is a great technology!

    LED is not a photofacial. The photofacial is usually IPL. This is explained in this post:
