448kHz RF Machine Description
448KHz RF Machine — Dual-Frequency Deep Care for Face and Body
The LANGWEN 448KHz RF machine (model DY.RF201A) works at two frequencies — 448kHz and 20kHz — to deliver comfortable deep-warming treatments for body firming, warming massage courses and facial care. One machine covers both beauty and wellness service menus, which makes it an easy add-on for salons that want a premium treatment without a premium price tag.
It comes as a complete system: 1 RES (resistive) handle, 1 CAP (capacitive) handle, 4 RES probes, 4 CAP probes and a fascia scraper — so face, arms, abdomen, thighs and back all have a matched head size. The smart touchscreen includes multi-language presets, and the compact 8.1 kg body fits any treatment room.
Why Two Frequencies?
Most single-frequency RF machines force you to choose between comfort and depth. This dual-frequency design separates the two jobs:
- 448kHz — the professional deep-care frequency. The frequency used by high-end European body-care devices, chosen for its balance of treatment depth and client comfort. In manufacturer testing it raised deep blood flow by 79% during a session.
- 20kHz — the supportive second frequency. A lower frequency reserved for targeted work on denser tissue areas, giving operators more control over how each treatment feels.
CET (capacitive) mode works on softer surface tissue and is the go-to for facial care; RET (resistive) mode reaches denser tissue and suits body sessions. Switching heads takes seconds, so one appointment can move from face to body without changing machines.

448kHz RF Machine Applications
Application Areas
One 448khz rf machine covers several paid services, which is why salons and studios treat it as a core room investment rather than a single-purpose device:
- Body firming and contouring — deep RF heating firms loose skin and smooths the appearance of stubborn areas such as abdomen, thighs and arms. The most requested RET service in body-sculpting studios.
- Facial lifting and skin care — CET handles with smaller probes suit facial work: softening fine lines, lifting the jawline area and improving overall skin appearance with comfortable warmth.
- Post-liposuction care programs — clinics use gentle RF sessions to help smooth tissue appearance during recovery programs, typically packaged as course-based follow-ups.
- Lymphatic drainage sessions — slow, warming passes support circulation and drainage routines, a natural add-on before or after body treatments.
- Sports recovery and physio-style support — RET deep-tissue work is used in recovery and comfort programs for muscle tension, popular with sports and wellness studios. Pair it with our 448KHz tecar therapy machine for a full recovery service menu.
- Cellulite reduction packages — combined with manual work, RF sessions fit multi-session cellulite programs that keep clients coming back. Many studios add a RF cryolipolysis fat freezing machine to complete the body program menu.
Because every service above runs on the same 448kHz RF machine, most salons package them as 6–10 session courses — higher ticket value and repeat visits from one device.

FAQ
What is the difference between CET and RET handles?
CET (capacitive) handles use an insulated head and suit softer, surface-level tissue — typical for facial care. RET (resistive) handles use a conductive metal head and suit denser tissue, so they are the choice for body sessions. This machine includes both, plus 4 probe sizes for each.
Why does 448kHz matter?
448kHz is the frequency associated with high-end European deep-care devices. It is valued for delivering comfortable warmth at depth — clients feel a pleasant heating sensation rather than harsh surface heat.
Does it include training or protocols?
we have online trainning and technolical support.
What warranty is included?
12 months for the main device and 3 months for accessories. Damage from improper use is not covered
