Potenza, Secret RF, or InMode: Which is right for my concerns?
- All three treatments are needle RF, but the difference in results wasn't due to 'output' but the needle method.
- Potenza excels at drug delivery, Secret at depth control, and InMode at broad targeting.
- The needle type is determined first based on my skin concerns (pores/scars/elasticity).
Information as of October 2026
Needle RF 3 Types: A Practical Comparison
- Needle Depth: 0.5-4mm
- Domestic Market Share: 70%
- Recovery Period: 3-7 days
Everyone talks about 'power difference,' but it's actually all about the needle method
When you search for comparisons between Potenza, Secret RF, and InMode, you'll most likely find power output figures first. However, what truly differentiates them is how the needles penetrate the skin. The doctor adjusts the power output anyway.
Potenza has drug injection ports at the tip of the needles (pumping method).
Secret allows for needle depth adjustment in 0.5mm increments, while InMode uses 25 needles simultaneously to cover a wide area quickly.
Potenza vs. Secret RF: Which is better for scars?
For concerns like acne scars with varying depths, Secret RF is advantageous. It can target shallow and deep scars differently within the same session by adjusting the needle depth in 0.5mm increments.
It has been most widely used for scar treatment since its FDA approval in 2008.
On the other hand, Potenza's key feature is the direct injection of drugs like growth factors and collagen boosters along with the needles. Without the drugs, the difference compared to Secret is not significant.
This adds drug costs, increasing the price by about 300,000 KRW per session.
Key Takeaway Potenza's drug injection is classified as 'Drug Delivery' by the FDA. The effectiveness varies depending on the drug used, so be sure to ask which drugs are used during your consultation.
O/X Quiz
Potenza, Secret RF, and InMode differ in effectiveness due to their varying power outputs.
Check the answer
X The power output for all three procedures is adjusted in real-time by the doctor. The real difference lies in how the needles penetrate the skin (drug injection, depth control, multi-targeting). Even with the same power output, the targeted layer and area vary completely depending on the needle method.
Why is InMode often recommended for 'pores and elasticity'?
InMode uses 25 needles simultaneously, covering a large area with a single shot. This makes it ideal for broad targets like the entire cheek or forehead.
For concerns like pores or overall elasticity where 'the whole area' is more of a focus than a specific spot, the treatment time is also short, around 15 minutes.
However, it's difficult to make fine adjustments to the needle depth. Therefore, it's more effective for improving surface texture rather than for indented scars with uneven depths.
If Secret is for 'spot targeting,' InMode can be considered for 'area targeting.'
| Procedure | Needle Method | Strengths | Average Cost |
|---|---|---|---|
| Potenza | Drug Injection Type | Scar + Drug Synergy | 400,000-600,000 KRW |
| Secret RF | Depth Control Type | Customized Treatment by Depth | 300,000-500,000 KRW |
| InMode | Multi-Needle Type | Wide Area Coverage | 250,000-450,000 KRW |
Costs may vary depending on the area, scope, drug type, and medical institution.
Organizing by My Concerns
For acne scars (varying depths), consider Secret RF; for pores and elasticity (wide area), consider InMode; and for scars with drug boosters, consider Potenza.
Dermatologists often recommend treatments in this order as a first choice.
However, even with the same device, the doctor's expertise is half the battle. Real-time adjustment of needle depth, power, and drug selection is crucial.
Choose a clinic that can provide a specific explanation of 'why this procedure for this concern' during your consultation.
- If the needle method doesn't match your concern type, you'll experience less than 30% perceived effect even after 3 sessions.
- Potenza without drugs shows minimal difference in results compared to Secret.
Needle RF Selection Criteria by Concern
Acne Scars (Varying Depths) [Secret RF]
- Needle depth adjustable in 0.5mm increments
- Targets shallow/deep scars in one session
- Effective for boxcar and rolling scars
Secret is advantageous if scar depths differ by more than 2mm
Enlarged Pores + Loss of Elasticity [InMode]
- 25 needles target simultaneously
- Covers wide areas like cheeks and forehead
- Treatment time around 15 minutes
If the goal is overall texture improvement rather than localized scars
When Scar Treatment + Drug Synergy is Desired [Potenza]
- Simultaneous needle and drug injection
- Choice of growth factors, collagen boosters, etc.
- Direct drug delivery to deep scars
Additional drug costs (100,000-200,000 KRW) apply
Choosing Based on Budget and Schedule
Budget under 300,000 KRW + Quick Recovery
Start with 1 session of InMode
Shortest treatment time and recovery period, allowing immediate return to daily activities.
Scar depths vary by area
3-session package of Secret RF
Customized treatment possible by adjusting needle depth in real-time.
Misconceptions
Myth Potenza has the highest power output, making it the most effective.
Truth The power output for all three procedures is adjusted by the doctor. Potenza's distinguishing feature is its drug injection capability, not its power output itself. When used without drugs, the results are not significantly different from Secret.
Before Your Needle RF Procedure, Be Sure to Check
- !!Needle RF is contraindicated for individuals with keloid tendencies or a history of gold thread lifting!! You must inform your doctor during the consultation.
- For 3 days immediately after the procedure, avoid bending your head down (washing face, yoga) as it can double or triple swelling.
- For drug injection types (Potenza), an allergy test for the drug components is mandatory.
Frequently Asked Questions
Do I need to try all three procedures to see results?
No. It's much better to repeat one procedure that suits your specific concern type 3-5 times than to do a little bit of all three. If the needle method doesn't match your concern, you'll experience minimal results even after 10 sessions.
Can I go to work the day after the procedure?
InMode is generally feasible, but with Secret and Potenza, swelling peaks around 48 hours. Avoid scheduling before important events by at least 3 days, and weekend treatments that allow for mask coverage are recommended.
What are the potential side effects?
Reported side effects include hyperpigmentation (if exposed to UV rays after treatment), temporary redness (3-5 days), and infection of needle marks (if aftercare is neglected). Sunscreen with SPF50+ is essential for 2 weeks post-procedure.
Lumi's Insight
With Needle RF, the priority is not 'which device' but 'whether the needle method suits my concerns'. Advertisements often emphasize power output, but in reality, how the needles penetrate determines the results. If you understand your skin concerns accurately before starting, you'll notice a significant difference even after the first session!
