The Nu Skin RenuSpa iO is a $419 device with a $74 gel attached to it, so it is worth using properly. This guide covers what Nu Skin actually specifies, what we would add from experience, and — importantly — one error this page used to carry that could have cost you money.
Correction First: Which Gel
The RenuSpa iO uses Nu Skin Conductive Gel. An earlier version of this page repeatedly named the Enhancer Skin Conditioning Gel instead. That was wrong. The Enhancer gel is sold as a hydrating gel in its own right and is not the conductive gel for this device.
If you bought the wrong one on our advice, tell us and we will sort it out — the 90-day guarantee covers opened product, and this one is on us. Our conductive gel guide sets out which gel goes with what.
What Nu Skin Claims for the Device
"Visibly contour, tone, and firm skin through skin stimulation with Nu Skin RenuSpa iO, our award-winning skin stimulation device. Using patent-pending Adaptive Microcurrent Technology that comfortably adjusts to your skin in real time, this device offers a smooth and comfortable massage helping your body feel refreshed and relaxed."
Also printed: "Visibly depuffs, contours, tones, and sculpts and reduces the appearance of dimples through skin stimulation" and "Skin stimulation helps visibly firm and tighten for a more youthful appearance."
That is the complete claim set. No mechanism, no timeline, no comparison with a salon treatment. This page previously carried stroke speeds in inches per second, stroke-overlap percentages, named lymph nodes and session durations in minutes. None of it could be sourced, and all of it has been removed.
Frequency
Nu Skin recommends three to five treatments per week. That is the one number on this page that comes from the manufacturer, and it is the number to build your routine around.
The practical version: pick your days in advance rather than deciding each evening. Four fixed evenings beats "whenever I remember", which in our experience means twice in the first fortnight and never again.
The Conductive Gel — the Step People Skip
Microcurrent devices need a conductive medium between the device and the skin. Skipping or skimping on the gel is the most common reason a device feels like it is doing nothing.
- Apply generously. The skin should look visibly wet, not lightly moistened.
- Reapply if it dries or absorbs partway through a session.
- Work in sections on the body, so the gel has not dried before you reach the last area.
- Do not substitute water, lotion or a random gel. Use Nu Skin Conductive Gel, which is what the device is sold to be used with.
Budget for it as a running cost rather than a one-off. That is the part people underestimate when comparing the device against a course of salon treatments.
Technique
We are not going to give you stroke speeds in inches per second, because nobody has published them. What is fair to say, and what any device of this kind rewards:
- Slow and deliberate rather than brisk. If it feels like you are hurrying, you are.
- Light, continuous contact. Pressing harder is not doing more.
- Upward and outward on the face and neck. Never dragging downward on the neck.
- Overlap your passes so you are not leaving strips untreated.
- Cover the area evenly rather than concentrating on the one spot that bothers you most. That is the instinct, and it is the wrong one.
What the Adaptive Technology Means in Practice
Nu Skin's own line is that the patent-pending Adaptive Microcurrent Technology "comfortably adjusts to your skin in real time". The practical upshot is that you have one fewer thing to think about: concentrate on coverage and pace rather than on settings.
Where It Fits in a Routine
Cleanse first, then treat. If you also use the ageLOC LumiSpa iO, that is two minutes of cleansing and then the RenuSpa session on the evenings you are doing both.
Alongside it, the supplements people most often pair with a device routine, each with Nu Skin's own claim rather than ours:
- LifePak Nano — "a comprehensive nutritional anti-aging program formulated with advanced levels of key nutrients and nanotechnology to help nourish and protect cells, tissues, and organs throughout the body."
- Beauty Focus Collagen+ — "a clinically proven collagen supplement formulated with bioactive collagen peptides, lutein, and phytoceramides to support skin radiance, hydration, texture, and overall appearance."
- ageLOC Youth — "formulated to help revitalize your body's natural aging defense mechanisms and promote your youth span."
Nu Skin makes no claim that these improve what the device does. They are separate purchases with separate claims, and we are not going to imply a combined effect nobody has published.
The Five Mistakes We See
1. Not enough gel
The most common by a distance. If the skin is not visibly wet, use more.
2. The wrong gel
See the correction at the top of this page. Conductive Gel, not the Enhancer gel.
3. Rushing
A hurried session is a wasted one. If you only have five minutes, do a smaller area properly rather than the whole body badly.
4. Inconsistent frequency
Five sessions one week and one the next is not the three-to-five-a-week Nu Skin recommends. Consistency beats intensity.
5. Using it on broken or irritated skin
Not on active breakouts, open skin, sunburn or inflamed areas. Wait until it has healed.
How to Judge Whether It Is Working
Nu Skin publishes no timeline for this device, so there is no week to look forward to. What we would do instead:
- Photograph before your first session — same room, same light, same time of day, no filter.
- Repeat monthly, not weekly. The changes claimed here are visual and gradual.
- Change nothing else at the same time.
- Decide inside 90 days, which is how long you have to send it back, opened and used, for a full refund. That 90 days is NuBodyRx's own; Nu Skin's published US refund window is 30 days from the purchase date.
Frequently Asked Questions
Which gel does the RenuSpa iO use?
Nu Skin Conductive Gel. Not the Enhancer Skin Conditioning Gel, which is a hydrating gel sold in its own right.
How often should I use it?
Nu Skin recommends three to five times a week.
How long does a session take?
Nu Skin does not publish a session length and we have removed the durations that used to sit here. Follow the instructions supplied with your device, and treat the area properly rather than to a clock.
Can I substitute another gel?
We would not. Conductivity is the whole point of the gel step, and the device is sold to be used with Nu Skin's.
