Sculptra vs Rejuran: which problem are you treating?

Sculptra and Rejuran are often compared, but they solve different problems. Sculptra is a poly-L-lactic acid collagen stimulator for wrinkles and gradual volume, with FDA premarket approval since 2004. Rejuran is a polynucleotide booster for skin quality, licensed in Korea but with no FDA record. Folds and hollows point towards Sculptra-type products; thin, dull or scarred skin points towards polynucleotides.

What is Sculptra?
Sculptra is a powder of poly-L-lactic acid (PLLA) microparticles, mixed with sterile water before injection [4]. Its US history runs through three premarket approval decisions held under FDA record P030050: facial fat loss in people with HIV in August 2004, nasolabial folds and other facial wrinkles in people with healthy immune systems in July 2009, and fine lines and wrinkles of the cheek in April 2023 (records checked 18 October 2026).
In Korea, Galderma Korea holds MFDS import permit 수허10-1161호, dated 4 November 2010, for a Class 4 tissue-repair material described as poly-L-lactic acid injected “to temporarily improve facial wrinkles in adults” (MFDS database, checked 18 October 2026).
What is Rejuran?
Rejuran is a Korean booster made of polynucleotides, purified DNA fragments from salmon, licensed by MFDS as a Class 4 device under permit 제허14-825호 since April 2014. It is placed as many small deposits in the skin to improve texture, hydration and thin skin rather than to add volume. Its variants, evidence and prices are on the Rejuran page.

How do Sculptra and Rejuran work differently?
The FDA describes Sculptra as a dermal filler, but it works differently from a hyaluronic acid gel filler. PLLA relies on a controlled foreign-body response: the particles prompt fibroblasts to make collagen, which builds new volume over time [1]. That is why results come gradually across a course.
What results can you expect from each?
Sculptra has the larger trial. In a randomised study of adults with moderate or severe cheek wrinkles, the treated group received up to one 150 mg vial per cheek at each session, with up to three more sessions a month apart. Response rates against untreated controls were 66.2% vs 38.6% at month 7, 70.6% vs 31.1% at month 9 and 71.6% vs 26.1% at month 12 [4]. The first efficacy assessment came at month 7, after the treatment course; because the effect builds gradually over that course, Sculptra suits people who are not working to a near deadline.

Rejuran’s trials are smaller and measure skin quality. In a split-face trial of 27 adults, the polynucleotide side showed higher improvement rates for elasticity, hydration, roughness and pore volume than non-cross-linked hyaluronic acid, with similar overall scores [5]. In a 30-person crow’s feet trial, 41.38% of Rejuran-treated sides improved at 12 weeks [6].
What are the side effects and risks?
With Sculptra, papules and nodules are the problem most often discussed, and they have been tied to how the product is reconstituted, spread in the suspension and injected, including injection that is too superficial [1]. A systematic review counted two confirmed reports of visual loss after PLLA, from injections near the eyes and nose and at the temple [7].
Who is each one suited to?
- A PLLA collagen stimulator such as Sculptra: hollowing at the cheeks or temples, deepening folds and wrinkles, and gradual volume loss, for people willing to wait several months for the full effect.
- A polynucleotide booster such as Rejuran: thin, crepey or dull skin, the delicate skin around the eyes, and atrophic acne scars, where texture matters more than shape.
- Neither: lines that only appear with expression, which respond to botulinum toxin, and marked sagging, which needs a lifting treatment rather than an injectable.
Many faces have more than one of these concerns at once. A useful consultation starts with the change that matters most to you, then works back to the product.
Sculptra vs Rejuran at a glance
| Sculptra | Rejuran | |
|---|---|---|
| Material | Poly-L-lactic acid microparticles | Polynucleotides from salmon DNA |
| Main aim | Wrinkles and gradual volume | Skin quality, thin skin, scars |
| US FDA | Premarket approval (2004, 2009, 2023) | No record |
| Korea MFDS | Class 4 import licence (2010) | Class 4 licence (2014) |
| Course in key trial | Up to four sessions, a month apart | Three sessions, two weeks apart |
| Follow-up in the trials cited here | 12 months | 12 weeks (crow’s feet trial) |
| Main risks | Papules, nodules; rare vascular events | Short-term bumps and redness |
Can Sculptra and Rejuran be combined?
Combining them is a clinical judgement rather than a tested protocol. A Korean survey describes polynucleotides used alongside fillers, toxins and energy-based devices for scars [9], but we found no study testing a Sculptra and Rejuran plan, so any combination needs an assessment of your skin and the two products.
What does each cost in Seoul?
Delight Dermatology Clinic in Seoul lists Rejuran Healer at KRW 300,000–500,000 per 2 cc session and a 5 cc Rejuran booster at KRW 550,000–800,000. Sculptra is not on its price list; its collagen stimulator is Juvelook Volume, a PDLLA and hyaluronic acid product listed at KRW 500,000–700,000 per vial. Prices checked 2026-10-18; confirm at consultation. Compare the Juvelook page if you are weighing a collagen stimulator. For Rejuran, the total depends on the amount used per session and the number of sessions; for Juvelook Volume, count the vials across the course; Sculptra needs a separate quote.
Which lasts longer, Sculptra or Rejuran?
Sculptra has the longer documented effect: its cheek-wrinkle trial reported responses at 12 months [4]. Rejuran’s crow’s feet trial reported results at 12 weeks, and maintenance sessions are usually planned.
Which hurts more, Sculptra or Rejuran?
Is Sculptra a skin booster?
Not in the usual sense. It is a collagen-stimulating dermal filler used for wrinkles and gradual volume, while boosters such as Rejuran target skin quality.
Is Sculptra the same as Juvelook?
No. Both are polylactic acid products, but Sculptra uses PLLA and Juvelook uses PDLLA with hyaluronic acid, with different licences and evidence.
