Microcurrent conductive gel: what it has to be, and what it does not

Conductive gel is the running cost nobody factors in and the first thing people try to skip. Skipping it does not reduce the treatment, it eliminates it.

Dry skin is a poor electrical conductor. Without a conductive medium between the probe and the skin, most of the current does not cross the barrier at all, and what does concentrates at the small contact points, which feels unpleasant.

The gel does two jobs: it provides a conductive path, and it provides slip so the probes glide instead of dragging. Both matter, and a medium that does one without the other is not a substitute.

• Water-based. Water carries the current. This is the non-negotiable property.
• Containing electrolytes, usually from the aloe or humectant base. Pure distilled water is actually a poor conductor; dissolved salts are what carry charge.
• Slippery enough to glide for the whole pass without dragging.
• Slow to dry. A gel that dries mid-pass stops working mid-pass, which is the most common practical complaint.
• Free of heavy oils and silicones. These are insulators. An oily product actively blocks conduction.

General rule: for a straightforward microcurrent device, a water-based conductive gel from any reputable source will work. For an app-driven system calibrated to its own gel, buying the brand's is the safer default.

• Facial oil or balm. Oil is an insulator. This is the single worst substitution and it produces no treatment at all.
• Thick moisturizer. Usually too occlusive and too oil-heavy, and it drags.
• Plain water. Conducts poorly, evaporates in seconds, no slip.
• Hyaluronic acid serum alone. Often fine conductively but dries far too fast to complete a pass.
• Ultrasound gel, sometimes suggested online. It conducts, but it is formulated for a different purpose and is not what any manufacturer specifies. If you use it, that is your call rather than ours.

1. More than you think, especially on the neck where it dries faster and the area is larger.
2. Work in sections. Gel one area, treat it, then gel the next. Covering the whole face at once means the first section has dried by the time you reach it.
3. Reapply mid-session rather than pushing a dry probe across skin.
4. Remove it completely afterwards if anything else follows in the routine - especially an LED mask, which should run on clean dry skin. The layering order.
5. Clean the device after every session. Dried conductive gel on contacts degrades conduction over time, and on seams it is just unhygienic. The FOREO BEAR 2 is the one device that solves this properly.

At five sessions a week for the first sixty days, the starter tube supplied with a device typically runs out within the intensive phase. Running out mid-protocol is one of the most common ways a sixty-day streak ends, and it is entirely avoidable by buying a second tube at the same time as the device.
