Restylane is a hyaluronic acid dermal filler, and for most international patients treated in Korea the correction holds for roughly 6 to 18 months before a maintenance top-up, depending on the specific product, the treated area, and how quickly your body metabolises the gel.
Restylane, a hyaluronic acid filler, typically lasts about 6 to 18 months in Korea before a top-up. Thinner products in mobile areas like the lips fade faster, while firmer gels placed deep for cheeks or nasolabial folds last longer. Your metabolism, the volume used, and the treated zone all shape longevity, so the clinic’s doctors set expectations at consultation.

Restylane is a family of hyaluronic acid (HA) dermal fillers made from stabilised, non-animal HA gel. Hyaluronic acid is a sugar molecule your skin already produces to bind water and give tissue volume and cushioning. When injected, Restylane restores lost volume, smooths folds, or refines contours, and because it is HA it can be dissolved with an enzyme if adjustment is ever needed. This adjustability is a key reason HA fillers are so widely used for international patients in Korea.
Restylane does not last forever because the body gradually breaks down the gel through normal enzymatic activity, a process called biodegradation. The filler slowly absorbs, water content shifts, and the corrected area softens back toward its baseline over months. This is expected and reversible, not a fault: it is why filler is considered a maintenance treatment rather than a one-time fix, and why occasional top-ups keep the result consistent.
How long a specific Restylane result holds depends on which product was used and where. The range varies because different Restylane gels have different particle sizes and cross-linking, and different facial zones move and metabolise at different rates. At Reberry Clinic, care is consultation-led: the clinic’s doctors match the right product to your area and goals, place a conservative amount, and explain the realistic longevity in English before you commit. We support patients across our operating Seoul locations (Gangnam, Myeongdong) and near Incheon Airport.
Hyaluronic acid filler longevity is governed mainly by the gel’s physical properties and by the biology of the site treated. Cross-linking is the most important factor: manufacturers chemically link HA chains so the gel resists the body’s hyaluronidase enzyme, and more heavily cross-linked, firmer gels degrade more slowly than soft, lightly linked ones. Particle size and gel firmness (measured as G-prime) also matter, which is why a structural product placed deep on the cheekbone can persist far longer than a soft product feathered into the lips. Placement depth counts too, because filler set deep against bone sits in a stable, low-movement plane, while filler in mobile areas such as the lips or around the mouth is squeezed by constant muscle motion and clears faster. Individual metabolism is the wildcard: patients with faster HA turnover, higher activity levels, or greater muscle movement in the treated zone tend to see filler resolve sooner, so two people given the same product can have different durations. Studies using ultrasound and imaging show HA can remain detectable in tissue for many months, sometimes longer than the visible cosmetic effect, which is why a doctor assesses the actual correction rather than assuming a fixed calendar date. Because so many variables interact, the honest answer to longevity is always a range, refined for you at consultation.

The doctor selects a Restylane gel suited to the zone, since firmer products for deep cheek support can outlast softer lip gels by 6 months or more.
Filler set deep, often against bone, sits in a low-movement plane and can persist longer than filler placed in mobile areas that clear within 6 to 9 months.
A measured amount, sometimes staged over more than 1 visit, avoids over-correction and lets the doctor build a natural result that ages down gradually.
The gel binds water and settles over 1 to 2 weeks, so the true result and its expected duration are assessed at a review rather than on day 1.
As the HA biodegrades over the following months, a smaller top-up refreshes the correction before it fully fades, keeping longevity consistent over years.

The clinic’s doctors assess your goals and anatomy, recommend a suitable Restylane product, and explain in English the realistic longevity range for your specific area.
After about 15 to 20 minutes of numbing, the injection usually takes roughly 15 to 45 minutes depending on how many areas are treated.
The correction is immediate, though mild swelling in the first 1 to 3 days can briefly overstate the final volume.
The filler integrates over 1 to 2 weeks, and a review lets the doctor confirm the settled result before planning any refinement.
Depending on area and product, results commonly hold about 6 to 18 months; a smaller top-up before full fade keeps the correction consistent.
Restylane typically lasts about 6 to 18 months, depending on the specific product, the treated area, and your metabolism. Firmer gels placed deep for cheeks or folds last longer than soft gels in mobile areas like the lips. You can explore options on our injectable fillers page.
Restylane fades because the body gradually breaks down its hyaluronic acid gel through normal enzymatic activity, a process called biodegradation. The corrected area slowly softens back toward baseline over months. This is expected and reversible, which is why filler is a maintenance treatment rather than a one-time fix requiring periodic top-ups.
Deep, low-movement areas such as the cheekbones and mid-face generally hold filler longest, often approaching 12 to 18 months, because the gel sits in a stable plane. Mobile zones like the lips and around the mouth clear faster, sometimes within 6 to 9 months, because constant muscle motion speeds breakdown of the gel.
Yes, different Restylane products have different particle sizes, firmness, and cross-linking, which strongly affects duration. Firmer, more cross-linked gels resist enzymatic breakdown and persist longer, while softer gels for delicate areas fade sooner. Your doctor matches the product to your area, which you can discuss on our injectable fillers page.
You see an immediate change on the day of treatment, but the true result appears after the filler settles over 1 to 2 weeks as swelling resolves and the gel integrates. Early swelling can briefly exaggerate the correction, so a review at around 2 weeks confirms the settled outcome before any refinement is considered.
Most people schedule a top-up before the correction fully fades, often around the 9 to 12 month mark, so the result stays consistent rather than dropping to baseline. The exact timing depends on your area and metabolism. A smaller maintenance amount usually suffices once a good base result is established at the first treatment.
Yes, a major advantage of hyaluronic acid filler is that it can be dissolved with an enzyme called hyaluronidase if you are unhappy or over-corrected. This adjustability makes HA a flexible, lower-commitment option compared with permanent materials. You can learn more on our injectable fillers page.
Yes, individual metabolism is a real variable in filler longevity. Patients with faster hyaluronic acid turnover, higher activity levels, or greater muscle movement in the treated zone often see filler resolve sooner. This is why two people given the same product can have different durations, and why any longevity figure is a range rather than a fixed guarantee.
Discomfort is usually mild because a topical anaesthetic is applied for about 15 to 20 minutes and many Restylane products contain lidocaine for added comfort. You may feel brief pressure or a small pinch. The doctor works slowly and carefully, and most patients find the experience very manageable overall.
Downtime is typically minimal, and most people return to daily activities the same day. Mild swelling, tenderness, or a small bruise can appear and usually settles within a few days to about a week. Avoiding blood-thinning supplements beforehand and using gentle cold compresses can help reduce bruising.
Many patients achieve their result in 1 session, with a small top-up at a review if any area needs refining. Larger or staged corrections may be built over 2 visits to avoid over-filling. Once a base result is established, maintenance is usually a single, smaller session every several months as needed.
Yes, HA filler is often combined with collagen-stimulating or skin-quality treatments for a fuller rejuvenation. Volume from filler can pair with texture and firmness gains from a skin booster like Rejuran Healer. Your doctor sequences treatments so each supports the others and your overall result lasts well.
Common, temporary side effects include bruising, swelling, tenderness, and mild redness at injection points, usually settling within days. Less common issues like lumpiness or asymmetry are typically correctable. Rare but serious vascular events are why an experienced doctor and correct technique matter. Contraindications are reviewed before any treatment proceeds.
For the first 1 to 2 days, avoid intense heat, saunas, and strenuous exercise, and do not massage the area unless instructed. Stay hydrated, use gentle skincare and daily sunscreen, and follow your doctor’s guidance. A supportive skin care routine helps maintain overall skin quality around your result.
Reberry Clinic treats international patients at our operating Seoul locations in Gangnam and Myeongdong, and near Incheon Airport, all with English-language support. The doctor helps you choose the most convenient location for your consultation and follow-up. You can plan your visit around a first session and a short review.
For a first session, 2 to 3 days is comfortable, allowing a consultation, the injection, and a short buffer for any swelling to begin settling. Because a review at around 2 weeks is ideal, some patients time a refinement on a return visit. Our English-speaking team helps coordinate your schedule around your travel plans.
Yes, flying within a day or so is generally fine after HA filler, which is a minimally invasive injection. Cabin air is drying, so hydrate well and be aware that mild swelling or bruising may still be settling in transit. Avoid heavy heat exposure and follow the aftercare your doctor provides while you travel.
International patients can complete treatment in one visit and receive remote check-ins in English between trips, so any questions are answered promptly. Maintenance top-ups can be timed to future visits to Korea. Continuing a supportive injectable fillers plan keeps your result consistent over time.
