What Is Juvelook

Definition

What is Juvelook made of?

The short answer

Juvelook is an injectable collagen booster made by the Korean company VAIM. Each vial combines poly-D,L-lactic acid (PDLLA), a biodegradable polymer, with hyaluronic acid, and the label calls it a PLA/HA hybrid filler. The hyaluronic acid hydrates the skin early. The PDLLA particles remain and prompt the skin to produce its own collagen over the following weeks.

Rewind uses two strengths, printed on the vial labels: Juvelook at 50 mg per vial and Juvelook Volume at 200 mg per vial.

The name PDLLA is where most online confusion starts. Lactic acid exists in two mirror-image forms, known as L and D, and either can be linked into a polymer. Using only the L form gives poly-L-lactic acid (PLLA), the material in Sculptra and in the Olidia line. Combining D and L forms gives poly-D,L-lactic acid, the material in Juvelook. The two belong to the same family and have been compared in the published literature, including a 2022 study of how their early volume effect differs.

In this product the hyaluronic acid plays a supporting part. It travels with the particles, makes the skin look hydrated for a short time and then disperses, leaving the polymer to do the slower work that the treatment is chosen for.

Mechanism

How PDLLA stimulates collagen, stage by stage

The next question patients ask is how a polymer can make skin produce collagen. In short, the skin treats the particles as something to respond to, and part of that response is new collagen laid down around them.

01Placement

Particles are spread through the skin

The doctor injects the preparation in many small amounts across the treated zone. The lower strength is placed closer to the surface for texture, and the Volume strength deeper where softness has been lost.

02Response

The tissue reacts to the particles

Research on the biological basis of polylactic-acid augmentation describes a controlled response in which fibroblasts, the cells that make collagen, become more active around implanted particles. Over time that activity is what thickens and firms the skin.

03Breakdown

The polymer is gradually absorbed

PDLLA is biodegradable, so the particles are broken down slowly by the body. A clinical histology study of injectable poly-L-lactic acid has examined how long the stimulating activity of this polymer family persists in tissue after injection.

04Outcome

What remains is your own collagen

Because the change is built by the skin, it appears gradually and looks like the same face with firmer, smoother skin. How long it lasts varies from person to person; Rewind's booster guidance gives a range from one to three months up to more than a year, depending on product and skin.

Pricing

What Juvelook costs at Rewind, strength by strength

Both strengths are listed per vial at the same rate. How many vials a treatment uses is set after the examination and written into your plan.

The figures above are per-vial list rates; VAT is charged in addition. The numbing cream applied before injection is covered by the rate. The number of vials and visits is confirmed at consultation.

Aftercare

After Juvelook: the two aftercare sheets

Because Juvelook comes in two strengths, the clinic's aftercare comes in two versions. Both are short, and neither asks for time away from work.

As with any injection there are risks. Redness, swelling, bruising and tenderness are common at first. Firm points or nodules where the particles were placed are the complication watched for with polylactic acid. Depth and dose are decided by the doctor for that reason. Infection and vascular occlusion are rare and serious; report worsening pain, blanching or any new lump promptly.
