What Makes 448 kHz the Gold Standard in RET‑CET Diathermy
The Science Behind 448 kHz in TECAR Therapy
TECAR diathermy relies on radiofrequency energy to stimulate cellular activity and promote internal tissue heating. Among various frequencies, **448 kHz** has emerged as the gold standard in RET‑CET devices due to its unique ability to target both superficial and deep tissues with precision and safety. This specific frequency was chosen based on clinical evidence showing its ability to:
- Maximize cellular ion exchange without causing thermal damage
- Stimulate fibroblast and myocyte repair mechanisms
- Maintain consistent energy transfer across variable tissue resistance
| Frequency | Clinical Application | Limitations |
|---|---|---|
| 1–100 kHz | Nerve stimulation, pain modulation | Too shallow, weak thermal effect |
| 300–500 kHz | Cell stimulation + endogenous heating | Higher range ensures safety + depth |
| 448 kHz | Full-body RET‑CET diathermy therapy | None clinically reported |
Benefits of Using 448 kHz in Beauty & Physio Settings
From anti-aging facials to sports injury rehab, the 448 kHz frequency offers broad-spectrum benefits by supporting:
- Improved microcirculation and cellular oxygenation
- Skin firming via collagen and elastin stimulation
- Pain relief and edema reduction
- Faster muscle regeneration and tendon healing
Compared to traditional RF frequencies, 448 kHz achieves deeper, safer, and more stable heating profiles—making it suitable for:
- Facial lifting & rejuvenation
- Body sculpting & cellulite reduction
- Arthritis, tendinitis, and lower back pain relief
| Treatment | Why 448 kHz Works Well |
|---|---|
| Facial skin tightening | Targets dermis without harming epidermis |
| Lower back pain | Reaches deep fascia & muscle layers |
| Arm firming | Enhances lymph flow and collagen fibers |
Why 448 kHz Is the Gold Standard in RET‑CET Devices
448 kHz has been validated by leading TECAR manufacturers, including INDIBA, and is known for its:
- Safe, non-invasive penetration profile
- Stable energy transfer across skin types
- Ideal frequency to trigger cellular bio-stimulation
- Compatibility with RET (resistive) & CET (capacitive) handpieces
Whether you're running a physiotherapy clinic or a beauty spa, choosing a RET‑CET machine that uses 448 kHz ensures you're delivering effective, research-backed care.
| Standard | 448 kHz Qualification |
|---|---|
| Medical RF classification | Yes |
| Validated by clinical studies | Yes |
| Global use in RET-CET machines | Yes |
