Lux Renew vs. Truth Rejuvenate

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
