So Sánh Rejuran, Juvelook & Exosome: Độ Đau, Vết Sần & Thời Gian Phục Hồi
So sánh chi tiết 3 dòng skin booster hàng đầu Hàn Quốc: Rejuran PN, Juvelook PLLA và Exosome. Giải đáp về độ đau khi tiêm, thời gian lặn nốt sần sẩn và cách chọn liệu trình phù hợp.
Achieving the celebrated 'Korean Glass Skin' look is one of the top reasons international travelers seek aesthetic procedures in Seoul. Among injectable treatments, skin boosters dominate online discussions. However, first-time patients are often alarmed by reports of needle pain, temporary 'embossing' bumps, or confusion over whether Rejuran, Juvelook, or Exosomes best fits their specific skin condition.
Summary: Rejuran PN focuses on DNA repair and moisture balance; Juvelook PLLA stimulates long-term autologous collagen for volume and acne scars; Exosomes deliver anti-inflammatory signals to repair damaged skin barriers.
1. Rejuran Healer (Polynucleotide / PN): The DNA Repair Standard
Extracted from wild salmon DNA fragments, Polynucleotides (PN) work at the cellular level within the dermis.
- Primary indication: thinning skin, fine lines, impaired barrier function, and compromised oil-water balance.
- Pain level: Moderate to high. Because PN has higher viscosity, micro-injections into the superficial dermis can feel sharp.
- Embossing bump timeline: Tiny raised bumps appear at injection points, typically resolving naturally within 24 to 48 hours.
2. Juvelook (PLLA + Hyaluronic Acid): Collagen Neocollagenesis
Juvelook combines Poly-L-Lactic Acid (PLLA) micro-particles with uncrosslinked Hyaluronic Acid.
- Primary indication: depressed acne scars, enlarged pores, lost skin elasticity, and structural thinning.
- How it works: Hyaluronic Acid provides immediate hydration while PLLA particles gradually stimulate your body's own collagen synthesis over 4 to 8 weeks.
- Pain & Downtime: Lower pain than Rejuran when diluted properly; minimal embossing bumps lasting 12 to 24 hours.
3. Exosomes (Exohealer / ASCE+): Cellular Signalers for Barrier Repair
Stem-cell derived extracellular vesicles contain growth factors, lipids, and microRNAs.
- Primary indication: active rosacea, severe redness, post-acne inflammation, and compromised skin barrier.
- Administration: Usually applied topically following microneedling (Potenza) or fractional laser channels rather than direct needle injection.
- Pain & Downtime: Minimal downtime (redness resolves within 6–12 hours).
