Density

How it works

Density, from Jeisys Medical, operates at 6.78 MHz and offers both monopolar and bipolar radiofrequency modes. In monopolar mode current travels through the body to a return pad and heats deeper tissue. In bipolar mode current passes between two electrodes on the handpiece and heats a shallower layer. Having both modes lets the operator build a plan that pairs broader depth with more superficial tightening, according to the area treated.

Good to know

• The catalog lists monopolar and bipolar RF at 6.78 MHz.
• Monopolar and bipolar modes act at different depths, which is its main contrast with single-mode units.
• It is considered for general laxity and contour in the lower face and neck.
• Mild redness is possible and results vary by person.

Where Density sits among similar devices

The dual-mode design is the feature that sets Density apart in an RF comparison. A single-mode device commits to one depth profile; this one lets the operator combine a deeper pass with a shallower one in a single visit. Whether that adds anything meaningful depends on how much of the concern is deep looseness versus surface slackness.

For readers weighing RF against ultrasound, the distinction remains that RF warms a continuous area while ultrasound concentrates energy in points. Against microneedle RF, Density does not penetrate the skin, so it is less suited to acne scars. A doctor can help decide which energy source suits the concern.
