Juvelook
What is Juvelook?
Juvelook is a PDLLA-based collagen booster that improves skin texture, fine lines, and elasticity by stimulating natural collagen regeneration. It delivers gradual and long-lasting improvements in skin density without the heaviness of traditional fillers.
What are the Benefits?
- Smooths skin texture by improving pores, fine lines, and overall skin quality
- Restores firmness naturally through PDLLA-based collagen regeneration
- Delivers long-lasting, refined results with subtle volume and enhanced skin density
Layer Collagen Remodeling
Targeting specific skin layers, Juvelook restores volume and refines texture simultaneously.
It stimulates natural collagen for long-lasting results.

Subdermal Delivery for Structural Support
In this stage, the product is delivered into the subcutaneous layer to support areas with deeper volume loss.
By reaching the lower tissue plane, it helps reinforce overall structural balance and enhances the foundation beneath the dermis.

Precise Dermal Injection for Skin Renewal
This step focuses on accurately delivering the formulation into the dermal layer, where collagen synthesis occurs.
By targeting the proper depth, it promotes refined texture, improved elasticity, and natural skin rejuvenation.
What is Hyaluronic Acid (HA)?
Hyaluronic acid is a gel-like substance that fills the spaces between collagen fibers in the dermis, providing exceptional moisture retention. It is abundant in infant skin but gradually decreases with age, making replenishment essential for maintaining healthy hydration.
※Hyaluronic acid (HA) is a conventional dermal filler ingredient and works through a different mechanism than Juvelook (PDLLA).
What is PDLLA?
PDLLA is a biodegradable polymer derived from the PLA family that directly stimulates collagen production within the skin. While hyaluronic acid (HA) focuses on replenishing moisture to deliver immediate hydration, PDLLA works by encouraging the skin to produce its own collagen, fundamentally improving skin firmness and density over time. Through this gradual regenerative process, natural volume is restored, and overall skin elasticity and texture continue to improve progressively.

Collagen Stimulation
Injected into the dermis using 30G or 31G needles, this treatment helps improve skin texture, redness, fine lines, pores, and acne scars.

Volume Formation
Using a 21G cannula or needle, the solution is delivered into the subcutaneous layer to enhance volume, lifting, tightening, and improve deep wrinkles.
Natural volume enhancement through self-collagen regeneration

Precise Injection Between Dermis and Fat Layer
Juvelook is injected into the space between the dermis and fat layer to address volume loss and wrinkles.

PLA Breakdown & Collagen Neogenesis
As PLA breaks down, it stimulates new collagen and supportive tissue formation.

Cautions
Cold compresses may help relieve pain, swelling, and bruising that occur after the procedure.
To help the product spread evenly, gentle massage for about one week after the procedure is recommended. Especially after Juvelook Volume treatment, the 5-5-5 rule is recommended to prevent lump formation and ensure even distribution of the product: massage 5 times a day, for 5 minutes each time, for 5 days.
For 24 hours after the procedure, be careful not to let water come into contact with the treated area, and begin washing your face or applying makeup according to the instructions of the medical staff.
For about 1 week after the procedure, it is recommended to avoid saunas, jjimjilbangs, swimming pools, strenuous exercise, excessive alcohol consumption, and smoking.
If severe pain or abnormal symptoms such as high fever, rash, blisters, pus, persistent swelling, or palpable nodules appear, contact the clinic immediately for consultation.
