Redox Gold vs. RENU 28: Which ASEA Gel Should You Use?

If you've looked at ASEA's topical range, you've probably hit the same question everyone does: Redox Gold and RENU 28 are both clear redox gels in similar tubes—so what's the actual difference?

The short version: they share the same underlying redox signaling technology, but they were built for two completely different jobs. RENU 28 is a skin product. Redox Gold is a comfort and recovery product. One extra ingredient is what separates them.

Here's the full comparison.

The Quick Answer

If you only remember one thing: gold is the dividing line. Redox Gold adds molecular gold to the redox formula, and that's what makes it a soothing and recovery product rather than a skincare one.

Same Technology, Different Formulas

Both products are built on ASEA's redox signaling molecules—the same cellular messengers your body produces naturally to support balance and communication. If that concept is new to you, How Redox Signaling Molecules Work in Redox Gold explains it properly.

Where they diverge is the ingredient list.

Redox Gold contains:

• Water
• Sodium magnesium fluorosilicate
• Sodium phosphate
• Sodium chloride
• Gold

RENU 28 contains:

• Water (Aqua)
• Sodium magnesium fluorosilicate
• Sodium phosphate
• Sodium chloride

That's it. The lists are otherwise identical—Redox Gold is the one with elemental gold added as a catalyst. Both are fragrance-free, alcohol-free, and free of dyes and additives.

What Each One Is Actually For

RENU 28: A Skin Product

RENU 28 Revitalizing Redox Gel is designed to renew and invigorate skin at the cellular level—improving how skin looks and feels on both the face and body. It's positioned as step two of ASEA's RENUAdvanced skin care routine, applied morning and evening after cleansing.

In a 28-day study, RENU 28 was shown to:

• Reduce eye wrinkle depth by 21%
• Improve wrinkles overall by 23%
• Improve facial skin texture by 22%
• Increase skin smoothness by 23%
• Increase skin elasticity by 20%
• Increase skin moisture by 11%

It has also earned Dermatest's 5-star clinically tested seal, their highest commendation for safety and efficacy.

Notice what's not on that list: nothing about muscles, joints, or a cooling sensation. That's not what RENU 28 was built to do.

Redox Gold: A Comfort and Recovery Product

Redox Gold Massage + Soothing Gel takes the same redox base and adds molecular gold to create a fast-acting gel for soothing support and recovery. It's aimed squarely at tired, overworked muscles and joints—use it before and after physical exertion.

Its evidence base looks correspondingly different. Redox Gold is clinically tested and dermatologist approved, developed in partnership with independent research universities, and thermographic imaging studies have measured an actual temperature decrease in the area where it was applied. Many users report noticing something within about 15 minutes of application.

The research is covered in more depth in Redox Gold Clinical Studies: What the Research Says.

Can You Use Redox Gold and RENU 28 Together?

Yes. ASEA itself frames these as two gels with two distinct roles, and there's no conflict between them—they're solving different problems in different places.

A sensible way to run both:

• RENU 28 as part of your morning and evening skin routine, on face and body
• Redox Gold on targeted areas around activity, or whenever you want comfort support

The only practical note: if you're applying both to the same patch of skin, let the first absorb fully before adding the second. Neither is doing the other any favors sitting in a layer on the surface.

Which One Should You Buy First?

It depends entirely on what you're actually trying to address.

Choose Redox Gold if:

• You train, run, lift, hike, or play sport
• You spend long days at a desk and feel it in your neck and shoulders
• You're on your feet all shift
• You want a cooling, soothing sensation in a specific area
• Muscle and joint comfort is the goal

Choose RENU 28 if:

• Your interest is in skin appearance, texture, and smoothness
• You want a daily face-and-body routine
• You're building out the RENUAdvanced regimen

Choose both if you want the skin benefits and the targeted comfort support—they're complementary, not overlapping.

A Note on Cost

Both products are sold in the same 3 fl oz / 90 ml size, and both are available at retail or at a lower subscription price through auto-ship.

If you're going to use either one consistently, the subscription route is meaningfully cheaper and earns Redox Rewards points on top. Current Redox Gold pricing by country is laid out in ASEA Redox Gold Price Comparison: Retail vs. Wholesale Costs.

Final Thoughts

Redox Gold and RENU 28 aren't competitors—they're siblings with different jobs.

RENU 28 is your skin gel: daily, face and body, focused on appearance and texture. Redox Gold is your comfort gel: targeted, gold-infused, focused on tired muscles and joints, with a cooling sensation you can actually feel.

If muscle and joint comfort is what brought you here, Redox Gold is the one you want. Not sure it fits your situation? Who Should Use Redox Gold? Best Use Cases walks through it person by person, and Where to Buy Redox Gold & How to Get the Best Deal covers your purchasing options.
