RET vs CET Radio Frequency: What’s the Real Difference?
💡 RET or CET — Which RF Technology Works Better for Skin Tightening & Body Sculpting?
Radio Frequency (RF) has become one of the most fundamental technologies in modern aesthetics.
But many clinic owners still ask:
“What is the real difference between RET and CET RF?”
“Which one should I choose for my clients?”
Although both are forms of RF energy, they work at different tissue depths and deliver distinct biological effects.
This guide breaks down everything clinics need to know.
🔥 CET (Capacitive Electric Transfer): Surface-Deep RF Tightening
CET RF uses capacitive electrodes to heat superficial and mid-dermal tissues.
This makes it excellent for skin quality improvement and tightening the surface layers.
✔ CET Works Best For:
-
Fine lines & early aging
-
Loose but mild skin laxity
-
Face, neck, and delicate areas
-
Clients who prefer very comfortable treatments
Client Experience:
✔ Warm sensation
✔ Zero discomfort
✔ Great for regular maintenance
Biological Effects:
-
Improves circulation
-
Stimulates fibroblasts
-
Smooths surface wrinkles
-
Boosts collagen density
⚡ RET (Resistive Electric Transfer): Deep-Tissue Thermal Activation
RET RF uses resistive electrodes that penetrate deeper layers including:
-
Fat tissue
-
Fascia
-
Muscles
This makes RET ideal for body sculpting, deep lifting, and stubborn fat pockets.
✔ RET Works Best For:
-
Double chin tightening
-
Jawline contouring
-
Abdomen and waist sculpting
-
Thick skin areas
-
Postpartum belly tightening
Client Experience:
✔ Strong warming
✔ Feels “deep and intense”
✔ Faster visible results
Biological Effects:
-
Deep collagen contraction
-
Increased metabolism
-
Improved fat mobilization
-
Muscle fascia tightening
🖤 RET vs CET: Clear Comparison Table
| Feature | CET RF | RET RF |
| Depth | 1–3 mm (superficial dermis) | 3–10 mm (deep tissue + fat + fascia) |
| Main Benefit | Skin tightening & texture improvement | Lifting, contouring, fat activation |
| Treatment Sensation | Warm & comfortable | Strong heat, deeper intensity |
| Best For | Face, neck, small areas | Body, jawline, stubborn fat zones |
| Result Speed | Gradual improvement | Faster visible lift & contour |
💡 Should Clinics Use RET or CET?
Choose CET if your clients need:
✔ Skin tightening
✔ Fine-line smoothing
✔ Mild rejuvenation
✔ Regular maintenance
Choose RET if your clients need:
✔ Deep lifting
✔ Subcutaneous fat activation
✔ Jawline contouring
✔ Body sculpting
🔥 The Best Strategy: Use RET + CET Together
This combination offers full-layer tightening:
-
CET: improves surface texture
-
RET: contracts deep collagen + lifts structure
Most high-end clinics use both technologies in one session for maximum tightening + sculpting synergy.
