CACI, Computer Aided Cosmetology Instrument, uses sub-sensory microcurrent to re-educate facial muscles and improve skin at a cellular level. The term 'non-surgical facelift' is overused in aesthetics. In this case, it genuinely earns it.
The problem CACI solves
Facial ageing is not simply a skin problem. The skin changes, it thins, loses collagen and accumulates pigmentation, but the underlying musculature changes too. Muscles that have elongated over decades contribute to nasal labial deepening, jowl formation, brow descent and the general softening of facial contours. Most aesthetic treatments address the skin. CACI addresses both.
How microcurrent works
The electrical current used in CACI is described as 'sub-sensory', meaning it operates below the threshold of sensory nerve perception. You do not feel a significant sensation during treatment; yet the current is sufficient to stimulate motor nerves, causing muscle contraction and re-education.
The specific waveform used by CACI mirrors the body's own bio-electrical field, the same low-level electrical activity that governs cellular communication and muscle function. This is not high-voltage electrical stimulation; it is the application of the body's own signalling mechanism with precision targeting.
Two mechanisms. One treatment.
1. Muscular re-education
The CACI technician uses two probes to work specific facial muscles using a technique called 'muscle shortening' and 'muscle lengthening'. Muscles that have elongated over time (the zygomaticus major, the platysma, the orbicularis oculi) are shortened and repositioned. Muscles that have contracted into set patterns are stretched and re-educated. The result is a visible restructuring of the facial contours, lifted brows, defined jawline, reduced jowling and softened nasal labial folds.
2. Cellular stimulation
At the cellular level, CACI has been shown to increase ATP (adenosine triphosphate) production by up to 500%. ATP is the energy currency of every cell in the body, it drives protein synthesis, cellular repair and metabolic function. In the fibroblasts of the skin, increased ATP production means significantly enhanced collagen and elastin synthesis. Over a course of treatments, skin texture, tone, hydration and firmness show measurable improvement that compounds session by session.
"After six sessions I had people asking if I'd had work done. I hadn't. That's precisely the point. The results are real and look completely natural."
The CACI Eye Revive application
The periorbital area, the delicate skin around the eyes, presents specific challenges in aesthetics. The skin here is among the thinnest on the face (as little as 0.5mm), making it both highly visible in ageing and highly sensitive to treatment. CACI Eye Revive uses specialist micro-heads designed for the periorbital anatomy, addressing fine lines, crow's feet, under-eye hollowing and upper lid heaviness with precision that larger applicators cannot achieve.
Why a course matters
A single CACI session produces a visible but temporary improvement, a post-treatment lift that fades as the muscles return to their habitual tone. The muscular re-education in CACI is cumulative: each session builds on the last, establishing new muscle memory and progressively improving the structural result. A course of 10 sessions, ideally twice weekly for five weeks, is the clinical recommendation for significant, lasting change. Monthly maintenance sessions are recommended thereafter.
Best paired with: Facial Electro Acupuncture (FEA) addresses the same muscular and skin quality concerns via different mechanisms, the combination produces results that neither treatment achieves alone. RF skin tightening adds a thermal collagen-remodelling component that further supports the CACI result.
Who is CACI for?
CACI is appropriate for anyone experiencing the early to moderate signs of facial ageing, and anyone who wants to prevent them. It is particularly valued by clients who want visible improvement without injectables; by those who have had injectable treatments and want to maintain and extend their results naturally; and by anyone for whom downtime is not an option.
There are few contraindications, CACI is not suitable for clients with pacemakers, epilepsy, active skin infections, or metal implants in the treatment area. Pregnancy is also a contraindication. All other skin types and ages can be treated.
CACI at Aesthetics Medispa
CACI treatments at Aesthetics Medispa in Watford are performed by Colin Solomon, who has been practising CACI for over a decade. Every session includes a full facial assessment and is tailored to the client's current skin and muscular presentation, not a fixed sequence applied to every face identically. Courses are structured around your specific goals and starting point.
Treatments that work. Results you can see.
Every treatment at Aesthetics Medispa begins with a thorough consultation, understanding your skin, your health and your goals before anything is recommended.
