JUVELOOK Skin Booster
JUVELOOK (VAIM Co.) is a PDLLA + HA hybrid skin booster — an MFDS-approved medical device in Korea. The HA component softens same-day; PDLLA stimulates collagen over 6–12 weeks.

PDLLA + HA Hybrid
HA gives same-day softening; poly-D,L-lactic acid microspheres stimulate collagen over 6–12 weeks.
Small, Spherical Particles
Small biodegradable microspheres minimize nodule risk and leave almost no residual substance.
Base vs Volume
Base JUVELOOK for superficial/mid-dermal boosting; JUVELOOK Volume (LENISNA) with ~4× PDLLA for deeper volumization.
Treatment Process
01Clinical Assessment
The dermatologist assesses skin concerns, goals, and history — checking lidocaine sensitivity, retinoid use, and nearby infection or dental work.
02Product Selection
Base JUVELOOK (superficial/mid-dermis) vs JUVELOOK Volume / LENISNA (deeper volumization, ~4× higher PDLLA dose).
03Reconstitution
Same-day reconstitution is permitted by manufacturer protocol — shorter than Sculptra historically required.
04Procedural Safety
Topical anesthesia applied; cannula strongly preferred for the tear trough and high-vascular-risk areas.
Recovery & Care
First 24–48h
Avoid heat, exercise, and facial massage. Call the clinic for severe pain, vision change, or color change.
Day 3–7
Resume normal skincare. Avoid retinoids until skin settles. SPF 50+.
Week 2–4
Schedule the next session per the induction protocol. Strict sun protection.
Long-term
Daily SPF 50+. Report any persistent nodule promptly.

Frequently Asked Questions
Q.Is JUVELOOK FDA-approved?
No. JUVELOOK is NOT cleared by the US FDA as an injectable. It is MFDS-approved as a medical device in Korea (since approximately 2021) and CE-marked in the EU. Several Gangnam clinic marketing pages incorrectly claim FDA approval — likely confusion with Sculptra (PLLA, manufactured by Galderma), which is FDA-approved and is a different molecule (L-isomer only, not the D,L racemic mixture in JUVELOOK). Honest regulatory framing is part of board-certified Anti-Aging specialist standards.
Q.How is JUVELOOK different from Sculptra?
Both are biostimulators that trigger fibroblast-driven collagen synthesis, but they differ in molecule, particle size, and formulation. Sculptra uses pure L-isomer PLLA (~40-63 μm crystalline microspheres), is FDA-approved with 25+ years of clinical evidence, and historically required pre-hydration. JUVELOOK uses D,L racemic PDLLA (~20 μm amorphous microspheres, per Jang 2026 PMID 42049428) pre-mixed with HA carrier for same-day reconstitution and immediate softening. An independent SNU/Sookmyung mouse comparator (PMID 42049428) showed PLLA produced greater collagen area than PDLLA at 12 weeks — so 'JUVELOOK better than Sculptra' is not supported by published data. The honest difference is formulation engineering: JUVELOOK offers faster reconstitution, smaller particles, and HA-driven immediate softening; Sculptra offers a longer global evidence track record.
Q.What is the difference between JUVELOOK and JUVELOOK Volume?
Same active ingredients (PDLLA + HA) but different formulations. Base JUVELOOK uses smaller particles for superficial-to-mid-dermal skin boosting (texture, fine lines, periorbital). JUVELOOK Volume — sold internationally as LENISNA — has approximately 4× higher PDLLA dose (~170 mg vs ~42.5 mg) and a thicker HA carrier for deep-dermal or subcutaneous volumization (mid-face, deep tear trough, jawline). Variant clarity matters: JUVELOOK Volume and LENISNA on different clinic menus are the same product.
Q.How many sessions and how soon will I see results?
Delight's induction protocol is 3 sessions at about 1-month (4-week) intervals — within the 3-6-week range reported in published JUVELOOK papers (tear trough: PMID 42098500; lower eyelid: PMID 40017393; pore reduction: PMID 40469551). The HA carrier provides subtle same-day softening; collagen-driven change becomes visible at 6-12 weeks and continues developing for several months. There is currently no published JUVELOOK study extending past 12 months — durability beyond that is not yet established by peer-reviewed data.
Q.What are the most serious risks?
Rare but serious: vascular occlusion, including blindness, from inadvertent intravascular injection — particularly in glabellar, periorbital, and forehead zones. The Lau 2025 expert consensus on PDLLA-HA200-induced visual impairment (PMID 41359890) is the authoritative safety document; clinic protocol should reflect its key safe-injection messages (cannula for high-risk zones, hyaluronidase emergency kit, anatomy-based depth control). Common transient risks include swelling, bruising, and mild erythema (~7-43% across published series); rare late-onset nodules have been documented — one published JUVELOOK tear-trough nodule case fully resolved with monopolar RF (Seo 2024, PMID 39283001).
