The problem with most home devices
Surface treatments fade. Dualsonic Optimum works where skin actually sags.
Most at-home tools warm the top layers and stop there. Loss of firmness starts deeper, in the dermis and the SMAS layer that clinics target with HIFU. Dualsonic Optimum reaches that layer, up to 4.5 mm, with focused ultrasound that leaves the surface untouched.

Patented dual-layer technology
Two depths, treated at the same time.

Dual-layer modes
Brow-up 1.5 and 2.0 mm, Face-up 2.5 and 3.0 mm, V-up 3.5 and 4.5 mm.

Professional-grade care at home

How to use
Four steps. Six minutes.
1
Gel and film.
Apply enough plain conductive ultrasound gel to the area and attach the cartridge film firmly so HIFU energy reaches the skin without obstruction.
2
Power on.
Press the power button briefly. The status display turns on.
3
Choose mode and level.
Press the mode button to pick Quick, V-up, Face-up, Eye-up, Brow-up or Neck-up, then set level 1 to 3.
4
Shot, then move to the next line.
Hold the head flat against the skin with no air gaps and press the shot/scan button. After each shot, move the device to the next line position and follow the protocol across the area, so no line is treated twice.
