The Best Conductive Gels for Microcurrent (and Ultrasound) Devices

Short answer: the best conductive gel for microcurrent is a fragrance-free, water-based gel you’ll actually keep using. Your device brand’s own gel (NuFACE Aqua Gel, ZIIP Electric Complex) is the safe default; a large professional tub such as 7E Wellness ReStore cuts the cost per ounce to a fraction. Generic conductive gels do the same job for microcurrent, according to Wirecutter. Prices below were checked on each brand’s US store on October 8, 2026.

Why microcurrent needs a conductive gel

Microcurrent devices pass a tiny electrical current between two contact points on your skin. A water-based gel gives that current an even path and stops the device from dragging. FOREO’s guide sums up what happens without one: discomfort, drag, a prickling “zap” and a less effective treatment. A good microcurrent gel is water-based with electrolytes or glycerin, glides without drying instantly, and rinses off cleanly. Oils, rich creams and thin toners are the things to avoid (FOREO).

Microcurrent gel price per ounce, compared

Checked October 8, 2026. Per-ounce figures are price ÷ size (100 ml ≈ 3.38 fl oz); “Not listed” means the brand’s product data didn’t give a size. Sale prices change often.

The pattern is clear: small brand bottles cost the most per ounce, and buying the largest size of the same gel usually halves the price. How long a bottle lasts depends on how thickly you apply it and how often you treat, which no brand publishes in a comparable way. Use the calculator below with your own numbers.

Best microcurrent gel for NuFACE

NuFACE Aqua Gel Activator

Sizes and prices

1.69 oz $35 · 3.3 oz $55 · 10 oz $80

Per ounce

$20.71 · $16.67 · $8.00

Made for

NuFACE TRINITY+, MINI+ and other NuFACE microcurrent devices (FIX uses its own serum activator)

NuFACE calls its gels “activators” and designs its devices around them, so this is the no-thinking option if you own a NuFACE. The economics depend almost entirely on size: the 10 oz bottle costs about $8 an ounce versus about $20.71 for the 1.69 oz. NuFACE also holds an FDA 510(k) for an electroconductive “NuFACE Gel Primer” (K161654, 2016); we couldn’t confirm whether today’s Aqua Gel is covered by it.

Best for ZIIP

ZIIP Electric Complex Gel

Price

$29.99; 2-pack $50.99; 3-pack $63.99 (size not listed in ZIIP’s product data)

Ingredients

Water, glycerin, propanediol and a short list of others; no added actives; free of oil, parabens, phthalates and fragrance, per ZIIP

ZIIP’s original gel is the plain option in a range that goes up to $89.99 for gels with added actives (Clear Gel with 1.8% salicylic acid is $59.99; Silver and Crystal are $79.99). For conductivity alone, Electric Complex is the one to buy; the 3-pack brings it to about $21 a bottle.

Using a FOREO BEAR? FOREO says its SUPERCHARGED Serum 2.0 is essential for BEAR and LUNA plus devices. It’s a conductive serum with added hyaluronic acids, squalane and ceramides rather than a plain gel, at $59 on FOREO’s site (checked October 9, 2026). FOREO’s product data doesn’t list the size, so it isn’t in our price-per-ounce table. See SUPERCHARGED Serum 2.0 at FOREOAffiliate link

NuFACE gel alternatives (and what not to use)

Wirecutter notes that generic conductive gels provide the same benefit as brand gels for microcurrent (Wirecutter). FOREO’s list of alternatives that work in a pinch:

• Pure aloe vera gel (water-based, no additives). Conducts, but dries faster than a dedicated gel.
• Ultrasound gel. Highly conductive and affordable, with no added skincare benefits.
• A hydrating gel moisturizer such as Neutrogena Hydro Boost Gel, which FOREO names as a budget option.
• Glycerin and water, if you want a DIY option.

Avoid facial oils (they block conductivity), creams and occlusive moisturizers, and watery toners or essences that don’t give enough slip (FOREO). FOREO’s top pick in its own guide is its SUPERCHARGED Serum 2.0 ($59 on FOREO’s site). For pairing serums and actives with every device type, see gels and serums to use with microcurrent, LED and ultrasound.

FDA-cleared conductive gels

Electroconductive media have their own FDA product code, GYB (“media, electroconductive”), a Class II category under 21 CFR 882.1275. Two beauty-device gels hold 510(k) clearances under it: NuFACE Gel Primer (K161654) and Jmoon Conductive Gel (K243749). Most other conductive gels are sold as cosmetics. Clearance tells you the gel was reviewed as a conductive medium; it doesn’t make it better at helping your skin.

Gels for ultrasound and RF devices

Ultrasound and RF devices also need a gel, for different reasons. Ultrasound can’t travel through air, so the gel couples the head to the skin. RF devices typically use a gel for glide and even contact.

• Ultrasound facial devices: glow.m sells its devices with its Moisture Booster Gel ($18.99 for 100 g), and THOME recommends its Boost Ampoules ($22.90 each; see our THOME The Glow review).
• RF devices: CurrentBody sells an RF Conductive Gel ($39.99 for 100 ml) for its Skin RF device.

Quadthera says any water-based conductive gel, including ultrasound gel or aloe gel, works with its devices, so you aren’t tied to its FORHERTZ 3D Booster Mask Gel ($26, or $79 for five). That makes ultrasound one of the cheaper device types to run. If you’re weighing up an ultrasound device, start with our Quadthera Titan review or the best at-home ultrasonic facial devices.

How to apply conductive gel

1. Cleanse your face and pat it dry.
2. Apply a generous, even layer to the area you’re treating first, rather than the whole face at once, so it doesn’t dry out.
3. Glide the device as your manual directs, keeping both contact points on the skin.
4. Re-apply as soon as you feel drag or tingling.
5. Afterward, rinse off or massage in the leftover gel, depending on the formula, then moisturize.
