For patients seeking both visible tightening and a deep upgrade in skin density, combining XERF(dual-frequency RF, 600 shots) with Re2O(hADM ECM skinbooster, 5cc) can offer comprehensive skin rejuvenation. At Seye Clinic Gangnam, this strategic pairing is tailored for fast recovery and noticeable improvement â all with zero to minimal downtime.
A patient came to us last week, frustrated that standard fillers and basic RF couldn't address her skin's texture and sagging together. She wanted not just a firmer jawline, but visible smoothness and that dense, fine-pored lookâcommon requests, but rarely solved together by one device.
Let's clarify: XERF is a non-invasive monopolar RF device using dual frequencies (6.78MHz + 2MHz) to deliver controlled heat energy at both shallow and deep levels. This means it tightens the deeper collagen network while refining the more surface-level texture.
Re2O, on the other hand, is a skinbooster injection â more specifically, it's the world's first to use human acellular dermal matrix (hADM) ECM. Rather than just "stimulating" your own collagen, it actually replenishes lost collagen and elastin (about 89% pure collagen per dose) directly into the dermis, improving volume, pore visibility, and skin resilience.
Combined, these modalities offer a two-front approach:
Together, they target both the structural (firmness/lifting) and biological (density/texture) factors of aging skin, all without surgical intervention.

Many patients ask us: âWhy not just do one procedure? Is combining worth it?â To answer, we compare key characteristics below.
Feature | XERF RF (600 shots) | Re2O Skinbooster (5cc) | Combination Approach |
|---|---|---|---|
Mechanism | Dual-frequency RF (deep + superficial heating) | Direct ECM/collagen supplementation | Both: immediate tightening + ECM replenishment |
Main Benefit | Skin tightening & lifting | Dermal density, pore/texture, skin tone | Structure and skin quality synergized |
Pain | Mild (cooling system) | Mild-moderate (after numbing) | Mild to moderate, well tolerated |
Downtime | 0â1 day | 0 days | Nearly none; fast return to routine |
Session Standard (Seye) | 600 shots for full face | 5cc (1 vial) per session | Both performed at optimal dose |
Who Benefits | Laxity, sagging, loose jawline | Thin skin, visible pores, sallow tone | Laxity + low density; deep and surface issues |
We are often asked about the efficacy of more diluted ("larger-cc") skinboosters sold elsewhere. At Seye, we administer 5cc of Re2O at optimal clinical concentration â avoiding excessive dilution, which only makes the volume appear higher without increasing active ingredients.
Understandably, patients want to know: Is it worth it? Will it hurt? How long does it last, and will it fit my life schedule?
1. Pain: Both procedures are designed for mild discomfort only. XERFâs 3-level cooling system minimizes surface heat, and Re2O is done after topical numbing cream, making both widely tolerableâeven for those anxious about pain.
2. Downtime: Expect almost zero downtime with XERF (0â1 day) and none with Re2O (0 days). Most patients return to work or social plans right after, sometimes with slight redness that fades in hours.
3. Durability: While every skin type is unique, we consistently see that:

4. Cost: Our approach at Seye Clinic prioritizes efficacy, not âbigger cc numbers.â The combination service is tailored based on full-face area, density required, and your priorities.
In clinical experience, most patients find the visible lift and textural clarity from the combination a major step above single-modality treatments.
When considering skin rejuvenation in Korea, the choice is about more than device brand. In Seoulâs Gangnam districtâa hub for advanced skincareâSeye Clinic stands out as a Re2O Certified Key Clinic and a leader in RF integration.
As a designated Re2O Key Clinic, we strictly adhere to optimal-dosage protocols â meaning one full Re2O vial (5cc) per session with no unnecessary dilution. This distinction reflects not just clinical training, but also access to manufacturer-backed educational resources, ensuring every treatment meets original development standards.
Our doctors frequently teach combination protocols to international practitioners. A detail that surprises many: when Re2O is mixed at lower concentrations elsewhere, visible dermal âbounceâ is much less, even if more fluid is injected into the skin. At Seye, purity and effect always take priority over just increasing the visible injection volume.
The clinicâs locationâ1 minute from Gangnam Stationâoffers effortless access for local and overseas visitors. Our cool gray and white interiors give a sense of calm and professionalism, matching the precise, data-based approach we bring to every case.
From the first step, the process is tailored for maximum effect and comfort: 1. In-depth Consultation: Our doctor analyzes your facial structure, skin thickness, and specific concernsâexplaining the synergy of tightening (XERF) with dermal rebuilding (Re2O). 2. Numbing: Topical anesthetic ensures the procedure is gentle, especially for Re2O. 3. XERF Treatment: Using 600 shots for comprehensive full-face effect, energy settings are adjusted across shallow, mid, and deep layers for both lift and surface refinement. 4. Re2O Skinbooster: Precisely 5cc (1 vial) is prepared and injected at key dermal depths, focusing on areas of texture irregularity, pore enlargement, or thinning. 5. Aftercare: With almost no downtime, post-procedure redness resolves quicklyâmost patients look and feel fresh before leaving the clinic.
Whatâs different at Seye? We never over-dilute; every Re2O vial is used to its full strength, and XERF energy levels are customized closely to your tissue profile. Our status as both a Re2O Key Clinic and a frequent host for visiting practitioners keeps us at the frontline of evolving protocols.
Q: How muchXERF and Re2O is used in one combination session at Seye Clinic?
A: For the full-face combination, we use 600 shots of XERF for tightening and 5cc (one full vial) of Re2O for the skinbooster, ensuring both layers are fully treated per optimal clinical guidelines.
Q: How quickly can I return to normal activities after the combined treatment?
A: Most patients experience no significant downtimeâparticularly with Re2O, where you can return to daily life immediately. XERF may cause mild redness for up to a day, but this fades quickly and typically does not interfere with routine.
Q: Is the pain significant during XERF or Re2O?
A: Both are tolerable for most patients. XERF uses a special cooling system to keep pain minimal, and we apply a numbing cream before Re2O injection. Any discomfort is brief and well-managed in our hands.
Q: Does a bigger cc number in Re2O skinbooster mean better results?
A: Not necessarily. At Seye Clinic, 5cc is the optimal, high-concentration dose per manufacturerâs guidance. Injecting larger volumes by diluting with saline may look like "more," but it actually decreases the collagen concentration and effectiveness.
