Rejuran vs Juvelook

Rejuran is a polynucleotide (PN) booster associated with skin repair and quality; Juvelook is a PDLLA booster associated with gradual collagen stimulation. They target different goals, so the better choice depends on your concern — a decision made with a licensed clinician.

Last reviewed: 16 Aug 2026

Key takeaways
  • Rejuran = repair/skin-quality signalling (PN)
  • Juvelook = gradual collagen stimulation (PDLLA)
  • Both are usually a course of sessions, not one visit
  • Compare the full plan, not a single per-session price

Rejuran and Juvelook are both injectable "skin boosters," but they work through different mechanisms and are usually discussed for different goals. Rejuran is a polynucleotide (PN) product associated with skin repair, hydration and quality. Juvelook contains PDLLA (poly-D,L-lactic acid) microparticles associated with gradual collagen stimulation.

Common early effectsInjection papules, swelling, bruisingSwelling, nodules or lumpiness if uneven

Which suits which concern? Rejuran is more often raised when the priority is overall skin quality, hydration and calming texture. Juvelook is more often raised when the priority is gradual collagen-based firmness. Many people are candidates for either, and some clinics discuss combining them — that decision belongs to a licensed clinician.

Price, number of sessions, injected amount and technique vary between clinics, so compare the full plan rather than a single per-session price.

Safety noteBoth are medical injectable procedures. Swelling, bruising, papules or nodules can occur depending on product and technique. Suitability, dose and depth are decided by a licensed clinician.

Common questions

How long does Rejuran last?
Durability depends on the person, the product, the number of sessions and skin condition. Results are usually built and maintained over a course rather than a single visit; ask your clinician for a realistic maintenance interval.
Can Rejuran and Juvelook be combined?
Some clinics discuss combining or sequencing boosters, but whether that is appropriate — and in what order — is a medical decision made after consultation.
Which has more downtime?
Both can cause swelling and bruising; PDLLA products can cause lumpiness if unevenly placed. Ask about expected downtime for your specific plan.
