“After autumn, my temples cave in, my cheeks flatten, and my nasolabial folds are so deep they catch foundation – my weight hasn’t changed, but my face looks like it’s ‘shrunk’.” This is a common anxiety for many women over 30 during seasonal changes. Hyaluronic acid fillers provide immediate results, but they are often metabolised within about six months. Repeated touch‑ups are not only costly but can also create an “artificial” look due to cross‑linker residues. The Korean Ellansé Collagen Regenerative Contouring System uses polycaprolactone (PCL) microspheres as its core. Instead of relying on physical filling, it continuously stimulates autologous collagen neogenesis, allowing hollow areas to “grow” their own full tissue – results are naturally progressive and last far longer than traditional fillers.
The primary action of hyaluronic acid is “physical filling” – it smoothes out depressions by occupying space in the injected area. This effect depends entirely on the external material. Once the HA is metabolised (typically 6‑12 months), the filling effect disappears. Moreover, residual cross‑linkers and osmotic changes during absorption can cause local skin laxity, making the original hollows appear even deeper. More critically, HA only addresses “volume” but does not improve the skin’s own “texture” or “support.”
Facial hollowing is essentially a loss of collagen and soft‑tissue atrophy. If the skin’s own “collagen factory” remains inactive, repeated filling is merely “robbing Peter to pay Paul.” The PCL component in Ellansé directly acts on the “factory” itself – instead of “delivering bricks” to the skin, it makes the skin “produce its own bricks.”
Ellansé is the world’s only “regenerative” filler to have received triple certification from the US FDA, EU CE, and China NMPA. It is often called the “Youth Inject.” Its core components are polycaprolactone (PCL) microspheres and a carboxymethylcellulose (CMC) gel carrier. Immediately after injection, the CMC gel provides instant filling (about 70% of the immediate improvement), while the PCL microspheres continuously release signals over the following 6‑12 months, stimulating fibroblasts to produce large amounts of type I and type III collagen and elastin.
Unlike traditional HA fillers, Ellansé does not rely on cross‑linkers to create “pseudo‑volume.” Instead, it induces autologous tissue proliferation, forming a dense “bio‑regenerative scaffold.” The final result integrates seamlessly with the patient’s own tissue – soft to the touch, natural in expression, with no “foreign‑body sensation” or “visible edges,” and the effect lasts 1.5‑2 years.
The CMC gel instantly fills hollows post‑injection, providing immediate visible improvement (about 70% of the effect). Meanwhile, the PCL microspheres continuously signal for 6‑12 months, inducing fibroblast proliferation and neocollagenesis that gradually “takes over” the support from the CMC. The final outcome is “1+1>2” – the immediate CMC effect combined with the long‑term PCL regeneration means the peak effect truly arrives at 3‑6 months and lasts far longer than HA alone.
New collagen not only restores volume but also forms a dense “collagen scaffold” in the dermis, significantly increasing skin thickness and elasticity. For skin thinned by photoageing or natural ageing (e.g., temples, cheeks, jawline), this “structural” improvement is especially evident – the skin becomes firm, resilient, and regains the youthful bounce that no longer “crumples” with a pinch.
Because the PCL stimulates autologous tissue regeneration, the new collagen integrates seamlessly with the original tissue – there is no “interface” or “boundary.” Therefore, during dynamic facial expressions (smiling, laughing, frowning), the treated areas move and deform naturally, without “prosthetic‑like” feel or “migration.” The touch is soft, indistinguishable from surrounding skin, with no “artificial marks” whether at rest or in motion.
The effects of Ellansé are “progressive” – they don’t immediately “prop up” an area after injection but gradually “grow” a natural contour as collagen deposits over time. This “slow and steady” characteristic ensures that the final result is highly harmonious with the existing facial bone structure and soft‑tissue proportions. There is no abrupt “local fullness with harsh transition” – whether for temples, cheeks, nasolabial folds, or jawline, the improvement is subtle and seamless.
Natural feel: The result is “grown” rather than “filled” – no jelly‑like sensation of HA, the touch is identical to your own tissue, and dynamic expressions are fluid and natural.
Harmonious integration: The proportions and transitions with the rest of the face are seamless – no “overfilled area next to hollow surroundings,” the overall contour is smooth and unified.
Personalised precision: Based on each individual’s degree of hollowness, skin thickness, and collagen regeneration capacity, the PCL microsphere concentration and injection depth are customised – a true “one‑person, one‑plan” approach, with results tailored to each need.
Long‑lasting durability: Once formed, autologous collagen can maintain results for 1.5‑2 years, and the decline is gradual – no frequent “re‑do” visits, turning anti‑ageing into a “single investment, long‑term benefit.”
| Dimension | Traditional HA Fillers | Ellansé (PCL) |
|---|---|---|
| Mechanism | Physical filling (cross‑linker support) | Immediate filling + stimulation of autologous collagen |
| Duration | 6‑12 months (fully metabolised) | 1.5‑2 years (sustained by autologous collagen) |
| Immediate effect | Visible immediately | Visible immediately (CMC gel) |
| Skin improvement | Volume only, no texture change | Thickness, elasticity, and radiance all improve |
| Dynamic performance | Possible migration, visible edges | Seamless integration, no migration risk |
| Number of sessions | Requires yearly repeat injections | Usually 1‑2 sessions, effects accumulate |
| Touch | May feel hard or “gel‑like” | Soft, consistent with autologous tissue |
Those with active infections, autoimmune diseases, pregnancy, or known allergy to PCL components should be evaluated by a doctor first.
💰 Cost Reference
In Korea, Ellansé is priced by dosage and area. A single syringe (1.0ml, containing PCL microspheres + CMC gel) for a basic treatment (single area, e.g., nasolabial fold) costs approximately 4,000,000 – 6,000,000 KRW. For moderate‑to‑severe facial hollowing (2‑3 syringes, temples + cheeks + jawline) the cost is about 8,000,000 – 14,000,000 KRW. Some premium clinics offer “staged” protocols (1‑2 sessions), with total costs around 12,000,000 – 22,000,000 KRW. The above includes injection fees, anaesthetic cream, and post‑care, but excludes oral supplements or additional repair products.
🕒 Recovery Timeline
Day of injection: Mild local redness and needle marks – cold compresses can help. Avoid extreme facial expressions, high‑temperature environments, and alcohol for 24 hours. Gentle cleansing is fine.
Days 1‑3: Redness subsides, needle marks close. The CMC gel begins to fill the hollows, and initial results appear. Mild swelling is normal.
Weeks 1‑2: Swelling fully resolves, the CMC effect stabilises – about 70% of the final result is visible. At this point, PCL microspheres start signalling, and collagen neogenesis begins.
Months 1‑3: New collagen gradually deposits – the treated areas become fuller, softer, and skin quality begins to improve (radiance, elasticity). The effect becomes progressively more evident week by week.
Months 3‑6: Results peak – the collagen network is dense, facial contours are full and firm, and skin tone is bright. A follow‑up evaluation can determine if a second session is needed for enhancement.
Months 6‑24: Effects remain stable; collagen slowly metabolises, but the overall state is still significantly better than pre‑treatment. A maintenance session is recommended at 18‑24 months to sustain the youthful appearance.
Facial hollows are the result of time “unravelling” the inside of your skin – taking not just volume, but the very texture and resilience of the skin itself. The wisdom of Ellansé lies in not rushing to “prop up” hollows with external force, but using PCL microspheres to awaken the skin’s own ability to produce collagen. When the newly formed collagen weaves a dense mesh in the dermis, you’ll understand – true sophisticated anti‑ageing is not “filled” in, but “grown” out.
