「做完超聲刀能維持多久?」、「麗珠蘭到底要多長時間打一次?」、「為什麼有些人效果維持得久,有些人一兩個月就反彈?」——這些是赴韓就診前最常見的疑問。本文以釜山弗洛麗雅皮膚科院真實案例數據為基礎,系統整理超聲刀、麗珠蘭、玻尿酸、Juvelook與Inmode五大項目的術後效果時間線,幫助你用合理的預期規劃赴韓就診的頻率與週期。
Effect timeline of HIFU: Results begin to appear 1 month after the procedure, reach their peak after 6 months, and a follow-up examination is required between 12 and 18 months.
The effects of HIFU (Shurink / Ultherapy) do not become apparent immediately after the procedure; rather, they gradually increase as Collagen is regenerated.
- Immediately after the procedure: Approximately 10-15% of the immediate tightening effect is due to the thermal contraction of collagen fibers.
- 1–4 weeks after the procedure: The contours begin to tighten slightly, and the jawline becomes increasingly defined.
- 1–3 months after the procedure: The peak period for collagen regeneration, resulting in significant Lifting effects on the contours
- 6 months after the procedure: The results reach their peak and remain stable thereafter.
- 12–18 months after the procedure: The effects gradually diminish; it is recommended to undergo a follow-up examination or additional treatment.
Director floria recommends that patients return to the clinic for a follow-up examination 6 months after their first HIFU treatment. The director will assess the recovery progress and determine whether additional treatment is necessary. For customers who wish to maintain stable results, it is recommended to undergo regular HIFU maintenance treatments every 12 to 18 months.

Time line of Rejuran’s effects: Results become visible 3 to 5 days after the procedure, and the effect lasts for 1.5 to 3 months per application.
Rejuran belongs to the category of regenerative glow treatments. Unlike ordinary moisturizing glow treatments that offer immediate results, Rejuran requires the PDRN components to accumulate in the dermis before noticeable improvements can be observed.
- iRejuran 1cc (regeneration, fine wrinkle improvement): The glow of the skin is enhanced 3-5 days after treatment; the effect lasts for approximately 1.5-2 months per application. It is recommended to receive one treatment every 1.5-2 months, with three treatments constituting a full course.
- Rejuran Blue Box: Elasticity improves significantly 1 week after the procedure, and the effect lasts for approximately 2 to 2.5 months per application.
- Rejuran HB: Deep tightening effects can be observed 2 weeks after treatment, and the effect lasts for approximately 2.5 to 3 months per application.
- Rejuran PN: Offers the strongest deep-repairing effects, with the effects lasting for approximately 3 months or longer per application.
- Rejuran HB: Contains anesthetic ingredients, resulting in a shorter recovery period after the procedure, and the effects last for the same duration as the corresponding regular versions.
Many customers have reported that “there is no visible change in the first few days after receiving Rejuran treatment, but after two weeks, they suddenly notice that their skin has improved.” This is a normal effect of the PDRN component at the dermal layer, and it does not indicate that the product is ineffective.
Juvelook Collagen: It does not take effect immediately, but its effects last longer than those of fillers.
Unlike Filler, Juvelook produces its effects in a gradual manner.
- 1–2 weeks after the procedure: Slight filling effect (about 10–20%), with visible improvements in contour immediately after the injection.
- 1–3 months after the procedure: The effects of collagen regeneration gradually become apparent, with reduced wrinkle depth and increased facial firmness.
- 6 months after the procedure: The effect of Collagen regeneration reaches its peak, and the results remain stable.
- 12–18 months after the procedure: The effects gradually diminish, and additional treatments are usually required.
The greatest advantage of Juvelook is its “long-lasting effect” – compared to Rejuran’s 1.5 to 3 months, a single treatment with Juvelook can provide results that last for 12 to 18 months, and the effects of collagen regeneration will continue to accumulate with each subsequent treatment.
Duration of Filler effect: The molecular size determines the rate of degradation; a follow-up examination is required after 1 to 2 years.
The duration of effect of Filler injections is closely related to the molecular size, cross-linking process, and the layer in which the Filler is injected.
- Small molecule Filler (for superficial use): Products such as Bao Rou Teng can last for approximately 6 to 12 months and are suitable for use on the lips and for treating superficial fine lines.
- Medium-molecular Filler: Such as Restylane, it lasts for approximately 12 to 18 months and is suitable for Tear trough correction and Nasolabial Fold Correction.
- High-molecular-weight Filler (for deep layers): Products such as Juvederm last for approximately 12 to 24 months and are suitable for the Apple Zone, the base of the nose, and the chin.
Director floria recommends that customers return to the clinic for a follow-up examination 12 months after the filling procedure. The director will conduct a physical assessment to evaluate the degradation of the filler and then decide whether additional injections are necessary.
Maintaining the effects of Inmode: Postoperative care determines the speed of rebound.
The effectiveness of Inmode’s facial lipolysis treatment depends on the extent to which the number of fat cells is reduced.
- Single treatment: Improvement in contours can be observed 2 to 4 weeks after the procedure.
- Complete treatment course (3-5 sessions): The number of fat cells decreases, resulting in more stable outcomes that last for approximately 1-2 years.
- Postoperative weight management: Inmode reduces the number of fat cells, rather than temporarily decreasing their volume. If weight increases significantly after the procedure, the remaining fat cells may expand, affecting the results of the treatment.
Floria’s post-operative management system: follow-up examinations at 2 months and 6 months, plus supplementary treatment programs
Floria is not a standard, routine clinic where treatment is completed in one go; instead, it provides systematic post-treatment care:
- Return to the hospital 2 weeks after the procedure: The hospital director will assess the recovery progress and ensure that there are no signs of infection or allergic reactions.
- 1 month after the procedure: The hospital director will recommend whether to start any supplementary treatments (such as high-frequency therapy) based on the patient’s recovery progress.
- 2 months after the procedure: Additional time points for treatments such as Rejuran and other hyaluronic acid-based treatments
- 6 months after the procedure: Evaluation of the peak effects of treatments such as HIFU and Juvelook
- 12 months after the procedure: Annual follow-up examination to determine whether maintenance treatment is necessary.
The advantage of this post-treatment management system is that the patient’s treatment records are continuously monitored by the same director, allowing for more precise adjustments to the treatment plan and preventing the disruption in information flow that often occurs when different doctors are involved in each visit.
Tips for maintaining results and saving money: How can you maintain the best results with the minimum number of treatments?
The most common concern among customers who go to South Korea for medical treatments is that “they have to undergo the entire procedure again every time, which is not cost-effective.” Floria’s strategic maintenance programs can help reduce long-term costs.
- The Rejuran treatment program is designed as follows: Three consecutive treatments constitute a basic course, after which the interval can be extended to once every 3–4 months – this approach is more cost-effective than starting each treatment from scratch.
- Alternating use of HIFU and Thermage: HIFU is used to maintain the fascia layer, while Thermage is used to preserve the dermis layer. The two methods are alternated every six months to ensure continuous skin firmness throughout the year.
- Juvelook annual treatment plan: Apply Juvelook 1-2 times a year to maintain Collagen levels and reduce the frequency of Rejuran injections.
- Postoperative daily care: Use the skincare and sun protection products recommended by the clinic to extend the duration of the effects.
Choosing to undergo cosmetic procedures at floria in Busan means not only selecting top-notch equipment and technology, but also opting for a systematic post-treatment management process. Only by scheduling treatments at regular intervals, rather than undergoing them whenever one feels the need, can one truly achieve long-term maximum results in anti-aging treatment.
