Juvelook Volume vs Sculptra: PDLLA vs PLLA Explained

No. Juvelook Volume and Sculptra are both collagen stimulators, but they are different products with different ingredients. Juvelook Volume uses PDLLA (poly-D,L-lactic acid). ^[1] Sculptra uses PLLA (poly-L-lactic acid). ^[2] You may hear Juvelook Volume called "the Korean Sculptra," and the comparison makes sense because both work the same general way: they encourage your skin to build its own collagen over time. ^[3] Outside Korea, Juvelook Volume is sold in some countries as Lenisna. ^[4][5]

One note before we start: we don't offer Sculptra at Glassy Skin Clinic. This article compares the two so you can understand what you are reading about, whether you are researching at home or planning a visit to Seoul.

Both are forms of polylactic acid, a material the body gradually breaks down and absorbs. ^[6][7] The difference is in their structure.

• PLLA (poly-L-lactic acid) is made from one form of lactic acid. ^[3]
• PDLLA (poly-D,L-lactic acid) combines two mirror-image forms of lactic acid, bonded in random order. ^[3][7] Vaim describes its particles as spherical, with a porous inner structure that breaks down slowly from the inside. ^[5]

In both cases, the particles are placed under the skin and the body responds by forming new collagen around them. The particles are slowly absorbed, and the new collagen remains. ^[3][6] That's why neither product gives an instant result. Changes build over several weeks to months. ^[2][8] With Juvelook Volume, in principle, your own collagen starts to form from about one month after treatment and keeps building over the second and third months and beyond.

Why the carrier matters

Juvelook Volume uses non-cross-linked hyaluronic acid as its carrier. ^[3] According to Vaim, it gives some early hydration and helps prevent needle clogging. ^[5] Because it is non-cross-linked, it isn't designed to act as a lasting gel filler. With both products, the main long-term effect comes from your own collagen. ^[3][6]

The instructions differ. Sculptra's official FAQ asks for massage 5 minutes, 5 times a day, for 5 days. ^[8] For Juvelook Volume, Vaim's UK partner recommends one firm massage of 1–2 minutes right after injection, with no daily home routine. ^[9] At our clinic, right after treatment, a nurse trained by our dermatologists shows you how to massage the area firmly for 1–2 minutes, and your dermatologist checks once more that you're doing it correctly. For the full comparison, see massage after Juvelook.

No. Sculptra has been FDA-approved in the US since 2004. ^[10] PDLLA is not among the filler materials the FDA lists as approved, so Juvelook Volume is not FDA-approved. ^[11] It is approved as a medical device in Korea, ^[1] so you may not find it at home. If you have it in Seoul, keep a note of the product name for your doctor at home.

Both products can cause swelling, redness, tenderness and bruising, which are usually temporary. ^[2][7] After Juvelook Volume (GLT™ Collagen Volume Lifting), swelling lasts 3–7 days on average; in some people it can last 10–14 days. In our clinic's experience this is part of the normal response as your skin starts building collagen. With both, firm lumps (nodules) can form, mainly when product builds up unevenly in one spot. ^[7] See Juvelook lumps and nodules. At our clinic, GLT™ Collagen Volume Lifting with Juvelook Volume isn't the right treatment for people who have had an autoimmune disease since childhood, such as Behçet's disease, lupus or rheumatoid arthritis. Every injectable treatment carries some risk, and your dermatologist will go through the ones that apply to you before treatment.

At our clinic, Juvelook Volume is delivered as GLT™ Collagen Volume Lifting, using GLT™ (Gentle Layered Treatment) with a blunt cannula, by board-certified dermatologists. At our clinic, we hydrate Juvelook with saline and add a local anesthetic for comfort. It's prepared in three mixing steps: vortex, a second vortex right before treatment, and syringe-to-syringe mixing (how we prepare Juvelook). We usually treat under-eye hollows together with the mid-cheek; see under-eye and mid-cheek hollows and how we plan your visits.
