Juvelook vs Sculptra vs Radiesse: Korea's collagen stimulators

'Collagen stimulator' or 'biostimulator' is a description, not a regulatory category. Galderma presents Sculptra as stimulating collagen, and Vaim describes Juvelook in similar terms. Korea's MFDS approval text is plainer: for both Sculptra and Juvelook, the approved use is temporarily improving adult facial wrinkles through physical repair. The makers' wording tells you how a product is marketed; it is not independent evidence of what it will do for you.

The documents also differ on what is in the syringe or vial. Sculptra's US label describes PLLA microparticles with sodium carboxymethylcellulose and mannitol, supplied freeze-dried and mixed with sterile water before use. Vaim says Juvelook combines PDLLA microspheres with non-cross-linked hyaluronic acid, and that the HA acts as a carrier and contributes to an initial physical effect; it gives no duration. The US FDA summary for Radiesse names it an injectable dermal filler: synthetic calcium hydroxylapatite suspended in a gel carrier of sterile water, glycerin and sodium carboxymethylcellulose.

Skin boosters, hyaluronic-acid fillers and Rejuran are separate products sold under other menu headings. Our skin booster guide sorts those names by the family each maker lists, and the treatment comparison guide maps them side by side.

If you searched for 'Korean Sculptra', there is no product by that name. Sculptra is sold in Korea under its own name: the MFDS lists it as an import by Galderma Korea, made for Q-Med AB of Uppsala, Sweden. The Korean-made products you may see beside it on a Seoul menu sit in the same MFDS category, a Class 4 tissue repair material (조직수복용재료). Vaim's Juvelook family and UltraV's Ultracol are two examples. Sharing a category does not make them the same material: Sculptra is PLLA, Juvelook is PDLLA with hyaluronic acid, and Ultracol is PDO.

Juvelook, Juvelook Volume and Lenisna come from one company, Vaim of Daejeon, so they are not three competing brands. Vaim lists Juvelook as 42.5 mg PDLLA plus 7.5 mg HA and Juvelook Volume as 170 mg PDLLA plus 30 mg HA, and its export site calls the larger product 'Juvelook Volume (Lenisna)'. The MFDS record puts Juvelook, Juvelook Volume, Lenisna, Juvelook i, Juvelook G, Juvelook Skin and Vivabella under a single permit, with Lenisna listed in 50 and 200 models. So the real question about Lenisna and Juvelook is which model and how much product, not which company. Ultracol is the one that differs in material: UltraV makes it from PDO, and its MFDS approval names bilateral nasolabial folds.

Across borders the regulatory picture is uneven. In the US, Sculptra has FDA premarket approval (PMA P030050), extended in 2023 to fine lines and wrinkles in the cheek region, and Radiesse has premarket approval P050052. We found no FDA premarket record for Juvelook or Ultracol. Two Juvelook phrases are easy to misread: Vaim's export site calls its PDLLA an 'FDA-approved material', which refers to the material rather than the Juvelook product, and Vaim's US site sells a Juvelook-branded topical serum marked 'not intended for injection', a different product from the injectable on a Seoul menu.

We do not have a verified, current Seoul price survey that matches products, models and amounts, so this guide gives no price range. What you can check is the unit. Sculptra's US label describes a 367.5 mg vial that is mixed with sterile water before use, and its clinical studies used different mixing volumes. Vaim packs Juvelook as a 50 mg vial and Juvelook Volume as a 200 mg vial. Radiesse is listed in Korea as 1.5 mL syringes. A quote in cc or mL alone therefore does not tell you how much product you get.

If two quotes differ a lot, compare the product name and model, the vial or syringe count and the mixing volume first; these can differ even when the menu name looks similar. Ask for each field below in writing and keep the clinic's own units. Our guide to how Korean clinic pricing works covers itemized quotes more generally.

We found no product-neutral source for how many sessions these products need, how far apart they are, how long recovery takes or how long any change lasts, so this guide gives none. Plans differ by product: Vaim's own FAQ describes a series of sessions and gives different intervals for Juvelook and Juvelook Volume, and says protocols may vary. Ask the clinic what it plans for you and on what basis.

Aftercare can matter more than the appointment on a short trip. Vaim's FAQ mentions avoiding strenuous exercise, saunas, hot baths and alcohol for a short period after Juvelook. Ask the clinic for the written aftercare instructions for the specific product, including any massage instructions, what a single visit is meant to do on its own, and who handles follow-up after you leave Korea. Our downtime planning guide helps you line a proposal up with your dates.

Which exact product and model will be used, and what material is it? How many vials or syringes, mixed to what volume, for which areas? Is a doctor consulting with you and performing or directly supervising the injection? How many visits does the plan involve, and what is the written total? What reactions should I plan for given my flight dates? What change is realistic for me, on what evidence, and what are the alternatives, including waiting?

Also confirm the clinic's identity. Medical Korea publishes a list of hospitals registered for attracting foreign patients; use it to check the registered name, then ask the clinic about its current services. Registration is a status you can check, not a quality score or a prediction of your result. Our clinic verification checklist walks through that step.
