FAQ
Rejuran vs Juvelook: Which Skin Booster Is Better in Seoul?
Quick answer
Neither is better overall; they solve different problems. Rejuran (polynucleotides) focuses on repairing thin, sensitive or damaged skin and improving texture, while Juvelook (PDLLA with hyaluronic acid) stimulates collagen for firmness, fine lines and shallow scars. At The Heal in Jamsil, Seoul, a dermatologist chooses based on your skin's main need. Send skin photos on KakaoTalk for a recommendation.

How do Rejuran and Juvelook work?
Rejuran Healer uses polynucleotides (PN) derived from salmon DNA. It is used to support skin repair, hydration and elasticity, and is popular for sensitive, thin or stressed skin. See Rejuran Healer .
Juvelook combines poly-D,L-lactic acid (PDLLA) microparticles with hyaluronic acid. The PDLLA acts as a gentle collagen stimulator, so improvement in firmness and fine lines builds gradually over weeks. See Juvelook .
Side-by-side comparison
- Main goal: Rejuran for skin repair and texture; Juvelook for collagen, firmness and shallow scars.
- Onset: Rejuran skin quality often improves after a couple of sessions; Juvelook builds over 1 to 3 months.
- Typical series: both often 2 to 4 sessions, spaced about 2 to 4 weeks apart.
- After treatment: both cause small bumps or mild redness for about a day; Juvelook bumps can last slightly longer.
These are general patterns, and results vary.
Which should I choose?
- Choose Rejuran if your skin is reactive, thin, dehydrated or recovering from lasers or irritation.
- Choose Juvelook if you want firmer skin, softer fine lines or improvement in shallow acne scars.
- For deeper volume loss, Juvelook Volume or other volumizers may suit better.
Some patients alternate or combine the two in one plan. Our glass skin booster program shows how boosters can be combined.
Who should avoid them?
Both are postponed during pregnancy and breastfeeding and over active skin infections. Rejuran is not suitable for people with fish allergy. Juvelook needs extra care in people prone to nodules or with autoimmune conditions. Mention any previous fillers or boosters at consultation.
