Juvelook (PDLLA) Singapore

Name: Juvelook Singapore — PDLLA Skin Booster | IN Eternity Clinic
Creator: Dr Sin Yong
Published: 2026-10-07

A booster that behaves like a slow stimulator.

Juvelook pairs poly-D,L-lactic acid with hyaluronic acid to prompt gradual collagen change in the skin. This guide explains how it works and where it fits. IN Eternity Clinic on Orchard Road offers Juvelook, and Dr Sin Yong advises at assessment whether it suits you.

Key facts

What it is: a powder of poly-D,L-lactic acid (PDLLA) microspheres with hyaluronic acid, mixed with sterile water before injection into the skin.
How it differs from PLLA: PDLLA belongs to the same polylactic acid family as the poly-L-lactic acid in Sculptra, but is a different polymer form used here in a more superficial, skin-quality role.
Typical aims: skin texture, fine crepiness, enlarged pores and shallow acne scarring; it is not a volumising filler.
Who it may not suit: people wanting an immediate change, anyone with active skin infection or inflammation, a history of nodules, or heavy existing filler in the area.
Cannot be dissolved: hyaluronidase breaks down the hyaluronic acid part only, not the PDLLA, so dose and depth are kept conservative.

How it works

What does PDLLA do in the skin?

Polylactic acids are biodegradable polymers that have been used in medicine for decades, in dissolvable stitches and implants. When small particles are placed in the skin, they trigger a controlled, low-grade tissue response in which fibroblasts lay down new collagen around them. The particles are then slowly broken down to lactic acid and cleared.

In Juvelook the PDLLA particles are porous and are supplied with a small amount of hyaluronic acid. The hyaluronic acid gives some early hydration, which fades within days to weeks. The collagen change from the PDLLA develops more slowly, across the weeks after each session, and is what any lasting improvement depends on. A related product with a higher PDLLA load is marketed for volume; this page concerns the skin booster use.

Suitability

Who it may suit, and who should look elsewhere

PDLLA boosters are generally considered for skin that looks thin, crepey or uneven in texture, for enlarged pores on the cheeks, and for shallow, rolling acne scars. People who want hydration and glow without a collagen-stimulating component may be better matched to a hyaluronic acid booster such as Profhilo; those whose priority is repair of thin, sensitised skin may suit a polynucleotide such as Rejuran. Where real volume has been lost, a structural collagen stimulator such as Sculptra or filler is a different conversation.

The under-eye area needs particular care. Published reports describe product tracking upward along the lower eyelid and firm nodules after PDLLA in the tear trough. If the eye area is a concern, Dr Sin Yong discusses whether a softer option is more appropriate before any plan is made.

Comfort

Does it hurt? Comfort and numbing

Most people describe a series of small pricks and a brief stinging or pressure as the product is placed. Numbing cream is applied for about 30 to 45 minutes beforehand, and some preparations include a small amount of local anaesthetic in the mix. Areas with thinner skin, such as near the nose and mouth, tend to feel more.

Treatment is usually given with a fine cannula or a series of small injections, depending on the area. You can ask for a pause at any time.

Timeline

What to expect: day by day

Day 0. Small bumps at the injection points, some redness and mild swelling. These usually settle within hours to a day. Massage instructions, if any, are explained at the session.

Days 1–3. Mild swelling and possible pinpoint bruises. Makeup can usually be applied after the first day if the skin is intact. Avoid saunas, strenuous exercise and facial treatments.

Week 1. The early plumpness from the hyaluronic acid starts to fade. This is expected and is not the result.

Weeks 2–4. Collagen change begins slowly. Firm lumps that persist should be reported rather than massaged hard at home.

Review. The skin is reviewed before any further session, usually four to six weeks later. A course is commonly two or three sessions, decided individually.

Safety

Risks, nodules and the registration question

Common effects are redness, swelling, bruising and tenderness. Less often, small papules or firm nodules form, particularly with superficial placement or high concentration; these may need treatment and can take time to resolve. Infection is uncommon with proper preparation. As with any injectable, placement into a blood vessel is rare but serious.

Because the PDLLA cannot be dissolved, a cautious dose is used and the first session is treated as a test of how your skin responds. Any injectable used in Singapore should be registered with HSA; the HSA registration guide explains how to check. Where older products have built up and the face feels heavy, see filler correction.

Myths and facts

Common myths, answered

Myth: Juvelook is a filler.
Fact: It is used as a skin booster for texture and quality. The early fullness is mostly hyaluronic acid and water and fades within weeks.
Myth: PDLLA and Sculptra are the same thing.
Fact: Both are polylactic acids, but they are different polymer forms used in different layers and amounts for different aims.
Myth: If I do not like it, it can be dissolved.
Fact: Hyaluronidase only breaks down the hyaluronic acid part. The PDLLA particles are cleared by the body over time, which is why dosing is cautious.
Myth: More product gives a faster result.
Fact: Collagen change takes weeks regardless of the amount. Higher doses mainly raise the risk of nodules.

Questions

Frequently asked questions

What is Juvelook?

Juvelook is an injectable skin booster that combines poly-D,L-lactic acid (PDLLA) microspheres with hyaluronic acid. It is used to support skin texture and quality by prompting the skin’s own collagen over the weeks after treatment. It is not designed to add shape or volume.

How is Juvelook different from Rejuran or Profhilo?

Rejuran is a polynucleotide aimed at repair and resilience. Profhilo is a high-concentration hyaluronic acid that spreads in the skin for hydration and firmness. Juvelook adds a collagen-stimulating polymer. Which suits you depends on your skin, your goals and the area, which Dr Sin Yong assesses in person.

How many sessions are usually needed?

Courses of two or three sessions, spaced about four to six weeks apart, are common. The number is set after assessment and adjusted to how your skin responds after the first session, because collagen change varies between people. Maintenance, if any, is planned later rather than booked in advance.

Can Juvelook be used under the eyes?

It has been used there, but published reports describe firm nodules and product moving along the lower eyelid after poly-D,L-lactic acid in the tear trough. The skin there is thin and the area is mobile. The under-eye area is assessed carefully, and a softer alternative may be recommended instead.

Who should not have PDLLA injections?

People who are pregnant or breastfeeding, those with active infection, inflammation or acne in the area, anyone with a history of keloids or nodules after injectables, and people with certain autoimmune conditions. Recent dental work or illness may also mean waiting. Your medical history is reviewed before any decision.

How much does Juvelook cost in Singapore?

Fees depend on the area treated, the amount of product, the number of sessions and whether it is combined with other treatments. Whether it is the right option for you is decided first; fees are then explained clearly at consultation.
