Skin Care Showdown: Lux Renew vs. Truth Rejuvenate

Lux Renew vs. Truth Rejuvenate
Is a Solution for:
Sagging Skin, Wrinkles
March 12, 2015 Reviewed by Marta 15 Comments

One of the questions I am most frequently asked is what is the difference between microcurrent and ultrasonic. Or, more specifically, what is the difference between my Truth Rejuvenate (microcurrent) device and my Truth Vitality Lux Renew (ultrasound and LED) device. And what variations of these questions really boil down to is: Which device is right for me? So here is the definitive skin care device showdown to help you make that decision.

Microcurrent: How it Works in a Nutshell

Microcurrent works at the muscular level to help firm the face.

Ultrasound: How it Works in a Nutshell

Ultrasound works at the cellular level to produce collagen and elastin.

In other words, these are different anti-aging technologies that have a different mechanism of working.

Microcurrent: A Deeper Dive Into How it Works

Microcurrent mimics the body's own natural bio electrical field and sends tiny electrical currents to our muscles.There is no muscle contraction. The muscle is woken up, and the current reminds it where it used to be (before gravity wore it down) and muscle memory is reactivated. You can read more about microcurrent in my Truth About Microcurrent article.

Ultrasound: A Deeper Dive Into How it Works

As the ultrasound waves pass from the treatment head to the skin they cause a vibration of the surrounding tissues, particularly those that contain collagen. You will not feel this vibration. The rapid oscillation of tissue created by ultrasound energy promotes movement of fluid waves against cells, facilitating movement between the inner and outer cells and thereby increased fibroblastic activity and collagen formation. You can read more about ultrasound in my Ultrasonic: How it Works article.

Microcurrent: What it Can Do for You

Microcurrent can re-educate muscles and help your face (and neck) look firmer. It also increases blood and lymph circulation. Microcurrent is also said to enhance the penetration of the active ingredients of skin care formulations.

Ultrasound: What it Can Do for You

By boosting collagen and elastin, ultrasound builds firmer, more supple skin. It is one of the best things I have found for sagging skin. Ultrasound also helps products and their active ingredients penetrate the skin.

A Word About Red LED Light

The Truth Vitality Lux Renew also has LED light (red for tackling wrinkles and fine lines and blue for acne). Red LED light strips away those water molecules that are involved in the immobilization of elastin, gradually restoring its elastic function and thus reducing facial wrinkles. Read more about how LED light therapy works as an antiager for skin.

How to Choose the Right Technology for You

Hopefully, it is now clear that these technologies work in different ways — at either the muscular or cellular level. In effect, therefore, they are complimentary, helping us look younger with different mechanisms. It makes sense to alternate these technologies in your anti-aging regimen — assuming funds permit.

But what if you can only choose one? Here's a checklist that may help you decide.


— I don't mind the tingly sensation
— I am very time-pressed and can only handle one technology in short sessions
— I can see loss of volume in my face, such as in my cheek and around my mouth
— My major concern is sagging and loss of muscle tone and I want the firming effects of microcurrent

Ultrasound and LED:

— I like that I can't feel anything
— I want to take the time to improve my skin and want to make the most of two technologies in one device
— I am concerned about lack of definition, such as around my jawline, and marionette lines
— My major concern is fine lines and wrinkles and I want the benefit of red LED light
— My major concern is sagging skin and/or loss of supple skin and I want the elastin and collagen-boosting effects of ultrasound

    Hi Mai, neither of these devices use a thermal technology. In order for fat to "melt", the device needs to reach a temperature of 56°C. Neither this form or ultrasound or microcurrent get warm, let alone hot. To understand the differences between thermal and non-termal ultrasound, please this article:

    It is my concern too about subcontaneous fat being broken down by one or both devices. Could anyone has used the devices, please share your experience. Thanks

    Hi Patricia, it really varies depending on how much time I have. But typically during a week, I alternate between ultrasound and LED and then either add microcurrent once or twice a week, or if get busy, I'll swap out one of the ultrasound sessions for microcurrent.

    Hi Marta, can you please tell us your beauty routine regarding how often you use LED, Microcurrent and Ultrasound? That would be very helpful for me in figuring out how to incorporate ultrasound into my routine which is microcurrent and LED. Thank you, Patti

    Thanks, Marta. What serum do you use when you use the light on the lip lines? Do you use the light and the ultrasound on the same day or alternate days? Do you use a serum when you use the ultrasound? if so, which one? Thanks!

    Hi Claudia, yes you can. I use red light and ultrasound on lip lines. The two modes may not be used at the same time on this device.

    First, does the LED red light work on lines around the lips? Can theultrasound & light used at the same time? Thanks

    I just bought the Truth Rejuvenate and I am exited. The tingling is not bad I think . Thanks Martha for this informative article.

    Hi MMG and Cristina, I addressed this in my article on how ultrasonic works. Some medical grade machines such as Ulthera or Lipoxonix for cellulite penetrate deeply and reach temperatures above 56 Centigrade. My home devices are not thermal - they do not heat up the skin and do not break down fat. You can read more about this here:

    Hi Sheri, I'm not sure why he would dismiss ultrasound other than he doesn't have it on his device. Personally, I think it is very effective. Our before/afters and clinical results are testimony.

    Hi Alice, NuSkin is a different technology. It is galvanic. The closest would be microcurrent and the Rejuvenate, but it is a little different. Regarding feeling anything, this is very personal. Some people do detect a sensation and others don't. NuSkin used to tingle so they may have toned it down, or you are one of the people who aren't sensitive to the sensation.

    Hi Marta: Thanks for the information on the idea behind these two machines. Last night I went to someone's house promoting NU skin and had them do a demo with the Spa device - they use and explained to me as micro-current. Which device of yours resembles theirs more? I sort of like the results...but don't get why you don't feel anything. You get a sense that it's not working and you have to wonder if you are just seeing results from all the moisturizing lotions and conducting lotions on your skin...Can y9u help me out here? ?

    I would also appreciate if you can answer this question (regarding subcontaneous fat being broken down by one of the devices) because it is a huge concern I have and it is the only thing is holding me from buying these 2 products.

    Marta, I'd like to know if you would comment on what was told to me over the weekend at the International Aesthetics Expo by a provider of LightStim. He said that within a few years, barring any new modalities, the 4 most important will be microcurrent, brushes, LED and microdermabrasion. He said ultrasound will not be a factor. I have beeen using microcurrent and your ultrasound. I keep the LED on with the ultrasound but was told LightStim is stronger. I really like the ultrasound!

    What was the concern posted by community member regarding subcontaneous fat being broken down by one of the devices. I didn't see response posted addressing that concern. I'm fearful of losing facial fat...causing more saging
