Rejuran is not a mandatory addition after RF microneedling such as Potenza. First define the goal to assess with RF alone, then check whether the separate change sought by adding PN justifies the extra cost and injection burden. Application onto the skin, delivery using a specific device tip and a separate manual injection after RF are different plans. At a SEOLREIM consultation, also request a quote without the added item and ask whether the equipment, product and method in the study match the proposed treatment.
If the reason for adding treatment is not explained, you can reassess after treatment alone
There are three options. RF alone focuses on the original skin-texture or selected-scar goal; adding PN requires separate confirmation of the expected incremental benefit and evidence; staged treatment postpones the next decision until recovery and response are assessed. A prospective split-face study published on 2026-9-28 (PMID 42808113) compared measures at 6 weeks in 25 women after Sylfirm-X FN-RF, with PN 2mL injected on one side and saline 2mL on the other. It reported advantages on the PN side in pore and wrinkle scores and hydration-related measures, but no significant differences in elasticity or dermal thickness. This was not a Potenza or topical-application trial, and the control side also received saline injections, so it differs from a strict RF-alone group without injections. The result does not establish the necessity of additional treatment for everyone, long-term durability or value for money.
| Decision factor | Questions to ask before adding treatment | Situations in which to defer the addition and reassess |
|---|---|---|
| Main goal | Which concern will be assessed with RF alone, and what is the additional goal of PN? | The two explanations overlap only in vague claims about regeneration or collagen |
| Actual method | Is this topical application after RF, delivery through a specific tip or a separate manual injection? | The amount applied topically is described as the injected amount, or the method is unclear |
| Match between the evidence and the plan | Do the study’s device, product, treatment area and control group match my plan? | A Sylfirm-X injection study is presented as direct proof for topical application with Potenza |
| Product and amount | What are the exact product name, intended use, and amount applied topically or actually injected? | Only the name Rejuran or the final cc amount is given |
| Additional burden | What are the separate requirements for pain control, bruising, papules and follow-up, and the additional costs? | A guarantee that recovery will not be prolonged or that risks will disappear |
| The next decision | If I choose RF alone, what are the aftercare and assessment date, and under what conditions should PN be considered later? | The only reason given is that the package must be completed before departure |
Definitions and how the treatments work
RF microneedling uses needles and radiofrequency heat, whereas PN injection places a separate product into tissue. The presence of needles does not mean the entire product is injected through their lumens. The manufacturer’s description of Potenza Fusion Tip delivery also concerns the design of a specific tip; it does not establish the delivery capability of every RF mode or tip, or clinical superiority of a particular Rejuran combination. Distinguish the exact products, ingredients and intended uses of Rejuran-family injectables from topical boosters and cosmetics; PN and PDRN are not interchangeable simply because of their names. Check Korean approved information and the relevant instructions for use separately.
Potential benefits and limitations
There is also evidence for topical application, but products and outcomes must be distinguished. A 2022 randomized split-face study compared topical REVS NCFS 140HPn combination PN serum with saline after Sylfirm; 29 of 30 participants completed it. After three treatments, some eye-area wrinkle measures improved faster, but the between-group difference in maximum wrinkle depth was not significant. This was not a direct comparison with topical Rejuran or manual injections. The two small studies cannot be combined to rank topical application against injection. Determine suitability for RF alone and necessary basic aftercare separately from whether PN is added; deep tethered scars, active inflammation or volume deficiency may require other assessment.
Who can seek a consultation and how suitability is assessed
Adults with an existing treatment goal appropriate for RF microneedling who have been offered an additional procedure may seek consultation. Report previous devices, areas, dates and injected products; past nodules, pigmentation or keloids; infection, herpes or dermatitis; allergies, medications and bleeding risks; pregnancy, breastfeeding and electronic or metal implants. Sensitive skin or possible redness after RF does not make PN an essential recovery treatment. If the skin is unstable, have treatment timing assessed before choosing an addition.
Procedure, recovery and scheduling
Before booking, request RF-alone and RF-plus-PN plans for the same area. Separating product, tip, whether energy is used, delivery method, actual amount, anesthesia, taxes, aftercare and medical fees clarifies what the additional charge covers. During consultation, set the assessment timing for the original goal and the conditions for discussing additions again, rather than following a fixed interval found online. Pinpoint bleeding, erythema, swelling, grid marks and microcrusts can occur; separate injections may add wheals, bruising and tenderness. Report photography and departure dates, and confirm instructions for washing, makeup, moisturizing, sun exposure and exercise, plus how to obtain care if problems arise. Erythema, swelling, microcrusts or injection marks can persist for several days or longer, so complete recovery during a short stay cannot be guaranteed.
Side effects, contraindications and symptoms requiring medical attention
Burns, scarring, infection, pigment changes, unwanted fat loss and nerve injury have been reported with RF microneedling. The US FDA’s 2025 safety communication addresses reports involving particular uses; it does not establish the complication rate of all Potenza procedures or a ban in Korea. Adding PN cannot be assumed to prevent these thermal injuries. Also ask about infection, hypersensitivity, persistent swelling, papules and nodules from separate injections. Worsening pain, blisters, skin color changes, altered sensation, spreading redness, pus, fever or visual disturbances require immediate assessment. Do not imitate needling procedures at home or apply products of your own choosing to open skin.
Compare treatment alone, topical application and separate injection as distinct choices
| Category | Role and goals | What to check |
|---|---|---|
| RF microneedling alone | The original goal established on examination and basic recovery care | Decide whether to add treatment after assessing the device, tip, treatment extent and response |
| Topical PN or delivery through a specific tip after RF | Adjunct goals for the exact topical product and protocol | Do not equate the amount used on the skin with the amount delivered into tissue |
| Separate PN injection after RF | Additional goals suited to the injectable product and treatment area | Check the actual method, such as manual injection or cannula, and added pain, risks and costs |
Questions and answers for a medical consultation
These questions for a consultation before visiting SEOLREIM are based on the literature. They are not a clinician interview or an individual prescription. This new article is awaiting confirmation of a separate review by a medical professional.
Q. Can I have Potenza without Rejuran?
A. If RF itself is suitable and no clear additional goal has been established, discuss treatment alone followed by reassessment. Choosing not to add PN is different from omitting necessary basic aftercare.
Q. Does the new study prove topical Rejuran after Potenza?
A. No. It compared separate injections after another RF device. It did not directly compare topical application with Potenza against manual injections or prove that everyone needs the addition.
Q. Are manual injections always more effective than topical application?
A. The studies reviewed used different products, areas and protocols. Different delivery routes alone cannot establish an outcome ranking; additional goals and burdens must be considered together.
Consultation with the SEOLREIM clinic director and signature programs
SEOLREIM Clinic describes its principles of consultation and treatment directly by the physician, genuine products, correct quantities and attentive care. Discuss Shining/Royal Rejuran and Silky Pore, which were confirmed on the official menu, in relation to your concerns; do not infer a specific PN product or mixture, RF device or tip configuration from the names alone. Ownership and availability of Potenza, Sylfirm-X and specific delivery tips require confirmation. Ask the physician whether a separate injection is needed for the current goal and how the alternative without an addition would be assessed.
Booking, languages, location and guidance for international visitors
When comparing RF/Rejuran combinations at Gangnam dermatology clinics, check the benefits and burdens added to the standalone plan rather than relying on a Seoul clinic’s package name. Overseas clients preparing to visit a clinic near Gangnam Station or elsewhere in Korea may find it helpful to send SEOLREIM the proposed device, product and delivery-method information together. The official international patient guide describes consultation support from on-site English- and Chinese-speaking staff and interpretation in 14 languages with advance booking; advance reservations are required before visiting. SEOLREIM Clinic is on floor 11 of Gangnam8258 Building, 376 Gangnam-daero, Seoul, approximately 1 minute from Exit 3 of Gangnam Station. Use the KakaoTalk, Naver booking and telephone channels below for Korean-language consultations and bookings, and the International consultation link for visits from overseas. Provide the treatment of interest, skin concerns, dates in Korea, preferred language and whether interpretation is needed. Confirm the actual scope of language support, costs, booking confirmation and cancellation terms before visiting. Depending on the examination, same-day treatment may be unavailable or follow-up after returning home may be needed; also discuss how to report adverse reactions and the actual scope of aftercare.
