1. What Makes 448 kHz Different: Endogenous Thermal Energy
Most RF devices heat skin from the surface down. The 448K Internal Fat Knife works the opposite way — it activates cells from within.
- Precision 448kHz frequency — delivers stable, precise energy tuned to maximize cell metabolic activity, with no scattering or energy loss.
- Endogenous (internal) heating — high-frequency resonance reaches deeper tissue layers with minimal loss, warming the target from the inside rather than burning the surface.
- Natural metabolic boost — the deep thermal response supports fat breakdown, improves local circulation and accelerates the body’s natural recovery, so results come from the body’s own mechanisms — safe to repeat session after session.
The result is a treatment that is deep enough to matter and gentle enough to be painless.

2. One System, Two Modes: CAP & RET
The 448K Internal Fat Knife is a dual-mode system. Two anatomically contoured handpieces, two distinct energy transfers, one complete body solution.
CAP Mode — Capacitive Energy (skin tightening)
- Stimulates collagen production for firmer, smoother skin
- Improves skin elasticity and firmness
- Refines texture for younger-looking skin
- Ideal for face, neck and skin-tone concerns
RET Mode — Resistive Energy (deep fat dissolving)
- Targets deep fat layers for effective fat reduction
- Helps reduce stubborn fat cells
- Sculpts body contours and promotes a slim, defined silhouette
- Ideal for abdomen, waist and thighs
Switch modes by changing handpiece — no extra module, no extra investment. Customizable intensity, treatment time and depth parameters let you tailor every protocol to the client’s body type and goal.
3. Deep Fat Targeting — Up to 30 mm, Including Visceral Fat
Where most non-invasive slimming devices stop at subcutaneous fat, the 448K Internal Fat Knife delivers energy to a treatment depth of up to 30 mm [to confirm: UI shows 30 mm]. This is what allows the system to address visceral fat — the deeper fat around internal organs that is linked to waist circumference and metabolic health — while tightening the overlying skin.
Typical treatment areas:
- Abdomen & waist — the #1 requested area
- Thighs
- Arms
- Face, jawline & neck — lifting and firming
- Flanks / love handles
What your clients see: measurable inch loss, smoother contours, firmer skin — not just temporary surface tightening.
4. A Treatment Clients Will Actually Complete: Painless, Zero Downtime
The #1 reason slimming treatments fail is client dropout. The 448K Internal Fat Knife removes the barriers:
- Non-invasive & safe — no needles, no surgery, no anesthesia
- Painless — clients describe a pleasant, deep warmth; most relax or fall asleep during treatment
- No downtime — return to work and daily life immediately after the session
- Comfortable session length — typical sessions around 30 minutes, easy to book into any schedule
