The latest offering from CACI International is the CACI Ultimate, a three-in-one system incorporating microcurrent, LED light therapy and crystal-free, orbital microdermabrasion.

First, the microcurrent toning phase uses patented electrical 'waveforms' at ultra-low frequencies to stimulate facial muscles for an instant firming effect.

Secondly, in a non-invasive alternative to dermal fillers, a 'wrinkle comb' phase combines specific wavelengths of light with high-frequency microcurrent stimulation to cause slight oedema and tissue inflammation; this activates the body's sodium-potassium pump, encouraging the release of sodium ions, collagen proteins and hyaluronic glycoaminoglycans (GAGS) to plump out lines and wrinkles and trigger tissue repair.

Thirdly, the microdermabrasion phase uses disposable abrasive tips for exfoliation without the maintenance and downtime issues often associated with crystal-based systems.

The treatment finishes with a silicon-based 'hydromask'.

The CACI Ultimate includes a colour touch-screen with 45 preset treatment programmes.
