Juvelook in Busan, Seomyeon
Korean PDLLA, quiet collagen builder,
no visible volume.

What is Juvelook / Collaum?
Gradual. Lasting. All your own collagen.
Juvelook and Collaum are Korean PDLLA (poly-D,L-lactic acid) collagen boosters. They contain biodegradable microparticles suspended in a gel carrier — injected into deep dermis or subcutaneous tissue, where they stimulate fibroblasts to build new collagen gradually over 4–8 weeks. The carrier dissolves in days; the collagen stimulation lasts 12–18 months. Juvelook is the original; Collaum is its refined successor with improved particle uniformity. Unlike filler, the result is not immediate — it emerges gradually as your own collagen builds.
The science
,
simplified.
Understanding the mechanism helps you set realistic expectations and choose the right brand for your goals.
Skin assessment
Dr. Lee evaluates skin density, fine lines, and overall quality. PDLLA boosters are ideal for those who want gradual, natural improvement — not immediate volume.
Topical numbing
Numbing cream is applied for 15 minutes before treatment. Most fillers also contain lidocaine, so injection discomfort is minimal.
Microneedle delivery
Juvelook or Collaum delivered via microneedle technique across the face. Targets dermis layer where collagen synthesis occurs. Even distribution for uniform improvement.
Instant result, 2-week settling
Results are visible immediately. Minor swelling and firmness resolves over 1–2 weeks, revealing the final natural-looking contour. Effect lasts 12–18 months.
Where we inject
,
and why.
Each area has its own anatomical target, typical volume, and result timeline. Dr. Lee will recommend a personalized plan during consultation.
| Treatment Area | Best For | Typical Dose | Visible In |
|---|---|---|---|
| Full face (dermal) | Overall thinning, aging | 1 vial (2ml) | 4–8 weeks |
| Jawline & lower face | Laxity, V-line loss | 1 vial | 6–10 weeks |
| Temples & mid-face | Hollowing, deflation | 0.5–1 vial | 6–10 weeks |
| Neck & décolletage | Crepey texture, sagging | 1–2 vials | 8–12 weeks |
| Hands | Thinning skin, visible veins | 0.5–1 vial | 6–10 weeks |
Korean & imported
,
side by side.
Both Korean and imported filler brands are clinically safe when administered by licensed dermatologists. Differences come down to cost, longevity, and specific properties.
| Brand | Price | Best For | Duration |
|---|---|---|---|
| Korea Juvelook (Standard) | ₩350,000 | First-timers, general collagen boost | 12–15 months |
| Korea Juvelook Volume | ₩500,000 | Face thinning, volume restoration | 14–18 months |
| Korea Collaum (Refined) | ₩450,000 | Most even distribution, lower bump risk | 14–18 months |
| Korea Juvelook/Collaum 2-Pack | ₩700,000 | Full protocol, ~10% savings | 16–18 months |

- Previously used filler and want long-term foundation
- Prefer building your own collagen to injected material
- Willing to wait 4–8 weeks for visible results
Not ideal for
- Want immediate visible results (try filler)
- Severe volume loss (need direct filler first)
- Active skin infections
- Autoimmune or connective tissue disorders
- Pregnant or breastfeeding
What happens after.
We believe in informed patients. Here's what to expect after treatment, and the full safety profile.
After your treatment
- Massage treatment area firmly 5 times/day for 5 days (essential for even distribution)
- Avoid heavy facial massage or extreme expressions for 3 days
- No saunas, hot yoga, or intense exercise for 72 hours
- Gentle cleansers and moisturizers for 1 week
- No facial treatments (peels, microneedling) for 2 weeks
- SPF 50+ daily to protect new collagen
- Visible improvement by 4–8 weeks; peak at 12 weeks
Possible side effects
- Mild swelling at bridge (2–3 days)
- Small bruising (resolves within a week)
- Tightness or firmness when smiling (2 weeks)
- Tiny redness at injection points (24 hours)
- Vascular occlusion (extremely rare with proper technique; Dr. Lee uses cannula to minimize risk)
- Tyndall effect — bluish tint from superficial placement (correctable)
- Asymmetric swelling (resolves as filler settles)
- Infection at injection site (very rare with sterile technique)
