Juvelook Before and After in Korea: PDLLA Results, Price & Honest Guide

2026-08-109 min read

When patients ask me about the Juvelook before and after they've seen online, the first thing I tell them is that this treatment is a slow-burn — and that's exactly why it looks so natural. Juvelook (and its close cousin Ultracol) work by prompting your own skin to make fresh collagen, so the change creeps in over weeks rather than appearing the moment you leave the room.
I'm Dr. Hyunji Kim, director at Delphic Clinic in Gangnam. I've treated hundreds of local and international patients with this PDLLA skin booster, and in this post I'll walk you through what it really does, the difference between Juvelook and Ultracol, who it genuinely suits, who I steer elsewhere, what it costs in Korea, and what a realistic Juvelook before and after actually looks like.
What it actually is — in plain language
Juvelook and Ultracol are injectable collagen boosters made from PDLLA (poly-D,L-lactic acid) microspheres suspended in a gel. When placed into the skin, they act as a gentle 'signal' that tells your body to produce new collagen around them. Over the following weeks, that new collagen is what firms, smooths and thickens the skin. Juvelook also includes a hyaluronic acid component that gives a little immediate hydration and glow, while Ultracol is often my choice for delicate areas like the under-eye.

Here's the honest part: this is NOT a filler and NOT a facelift. It won't sculpt a jawline overnight or replace big volume loss. If you want dramatic lifting, we'd talk about other tools. What Juvelook does beautifully is improve the quality of your skin — the fine crepey texture, dull tone, and early looseness that make skin look tired.
Juvelook vs Ultracol — what's the difference?
This is one of the most common questions I hear, so let me be specific. Both are PDLLA collagen boosters, so the core mechanism — stimulating your own collagen — is the same. The practical differences come down to composition and where I use them:
- Juvelook contains a hyaluronic acid (HA) component, which gives a little immediate hydration and glow on top of the collagen-building effect. It's my go-to all-rounder for overall face firmness, texture and that 'lit-from-within' quality.
- Ultracol is a PDLLA booster I often reach for in delicate zones — especially the under-eye — where a lighter, precise placement suits thin, crepey skin and I want to avoid any lumpiness.
- In many patients I combine both across different areas in the same plan. The choice isn't 'better vs worse' — it's matching the product to the skin in front of me.
Who it's really for
In my clinic, the people who get the happiest Juvelook before and after results tend to share a few things:
- People in their late 20s to 50s noticing dull, thin or crepey skin texture
- Anyone wanting overall firmness and glow without looking 'done' or over-filled
- Those with fine under-eye crepiness who are good candidates for Ultracol specifically
- Patients who prefer a natural, gradual improvement over an instant change
- Busy or travelling patients who need minimal downtime and can't take time off
And who I steer elsewhere: if you have significant sagging or deep volume loss, a collagen booster alone won't satisfy you — you'd likely want lifting devices or volume filler instead. If you're pregnant or breastfeeding, have an active skin infection in the area, or a history of keloid or certain autoimmune conditions, I'll usually recommend waiting or choosing a different route. Honesty upfront saves disappointment later.
How it compares — an honest comparison
Patients often ask me about Juvelook vs Ultracol vs Rejuran vs filler. They overlap but do genuinely different jobs — here's how I explain it:
In short: Juvelook and Ultracol are about rebuilding skin quality from within, and they layer nicely with other treatments rather than competing with them.
Before and after: what's realistic
Let me set honest expectations. Right after your session, you might look slightly puffy or see tiny needle marks — that's not your result. The real Juvelook before and after emerges over 2-3 months as new collagen forms. Patients typically describe skin that looks firmer, smoother and more 'lit from within,' with softened fine texture. It's the kind of change your friends notice as 'you look well-rested' rather than 'what did you have done?' A full course of 2-3 sessions gives the most convincing result, and it builds — not fades — in the weeks after each visit.
A rough timeline of what to expect: in the first week you settle from any minor redness or bumps; by weeks 2-4 skin already feels a touch smoother and more hydrated (especially with Juvelook's HA); the more meaningful firmness and texture change arrives around weeks 6-12 as collagen matures. That's why I plan sessions about 4 weeks apart and judge your true result a couple of months after your last visit — not the day you leave.

4. Back to your day
Some redness or tiny bumps are normal and settle quickly. Most patients head straight out — dinner, sightseeing, or the airport tomorrow are all fine.

5. Results build over weeks
Collagen forms gradually, so your skin keeps improving over 2-3 months. We plan your next session about 4 weeks apart for the best before and after.

How we do it at Delphic — and why it matters
This is a doctor-led treatment at Delphic — I plan and perform it myself, because injection depth, product placement and dosing per area genuinely change the outcome. We only use genuine, properly stored product, and I tailor how much we place (2cc vs 4cc, and Juvelook vs Ultracol) to your skin rather than a fixed template. For me, the goal is always subtle and natural — refreshed skin, not an obviously treated face.

How much does Juvelook cost in Korea?
Pricing depends on how much product you need and which areas we treat. As a guide, 2cc typically covers one area or an under-eye Ultracol treatment, while 4cc suits a full face or a larger plan. Here are our genuine, transparent prices:
| Juvelook/Ultracol Skin Booster 2cc (1 area / Under-eye area only Ultracol) | ₩250,000$180 |
| Juvelook/Ultracol Skin Booster 4cc (Full Face / Under-eye area only Ultracol) | ₩500,000$360 |

The treatment is one-day friendly with minimal downtime, and we're a direct, short walk from Sinnonhyeon Station Exit 3 in Gangnam. And to say it again clearly: you pay the same price as locals.

Frequently asked questions
What is a Juvelook before and after really like?
Right after your session you may look slightly puffy with tiny needle marks — that's not your result. The real Juvelook before and after emerges over 2-3 months as new collagen forms. Patients describe firmer, smoother, more 'lit-from-within' skin with softened fine texture. A full course of 2-3 sessions gives the most convincing change, and it keeps building — not fading — in the weeks after each visit.
What is the difference between Juvelook and Ultracol?
Both are PDLLA collagen boosters that stimulate your own collagen. Juvelook contains a hyaluronic acid component for a little immediate hydration and glow, so it's a great all-rounder for firmness and texture. Ultracol is my frequent choice for delicate areas like the under-eye, where a lighter, more precise placement suits the thin skin. We choose between them based on your skin and target area — not a fixed template.
How much does Juvelook cost in Korea?
At Delphic: 2cc (one area / under-eye Ultracol) is ₩250,000 and 4cc (full face / under-eye Ultracol) is ₩500,000. Same price for locals and visitors — no foreigner mark-up. Your exact plan and cost are confirmed at your free 1:1 consultation.
Does Juvelook hurt?
Most patients find it very manageable. We apply a strong numbing cream for about 20-30 minutes first, and Juvelook/Ultracol is injected with a fine needle or cannula. You'll feel small pinches and some pressure, but it's brief. Slight tenderness afterward is normal for a day or two.
How long does Juvelook last?
Because Juvelook and Ultracol stimulate your own collagen with PDLLA microspheres, results build over 2-3 months and typically last around 12-18 months after a full course. It's not permanent — collagen naturally turns over — so a top-up once a year keeps things looking their best.
How does Juvelook compare to Rejuran or filler?
Rejuran (PN/PDRN) is about calming and repairing skin quality; filler adds volume in a defined spot. Juvelook and Ultracol sit between them — a PDLLA collagen booster that improves overall skin firmness, texture and subtle bounce without looking 'filled.' Many patients combine them for a fuller result.
Is there downtime with Juvelook?
Very little. You may have tiny needle marks, some redness, and occasionally small bumps or bruising that settle within a few days. Most people return to normal activities the same day, which makes it very one-day-trip friendly.
How many Juvelook sessions do I need?
Most patients do 2-3 sessions spaced about 4 weeks apart for a meaningful before and after, then maintenance once or twice a year. Your skin condition and goals decide the exact plan — we confirm this at your free consultation.
Can I do Juvelook on a one-day trip to Seoul?
Yes. With minimal downtime, most visitors are comfortable heading to dinner, sightseeing or the airport the next day. We're a short, direct walk from Sinnonhyeon Station Exit 3, with on-site English and Chinese interpreters, so a single visit is easy to fit into a Seoul trip.
