Skin Boosters: What's Different?
Rejuran and Juvelook are both popular skin booster treatments, but their approaches are fundamentally different.
Rejuran
- Active ingredient: Salmon-derived PN (Polynucleotide)
- Mechanism: Aids DNA repair of damaged cells for natural regeneration
- Specialization: Skin elasticity, fine lines, skin texture
Juvelook
- Active ingredient: PDLLA (Poly-D,L-Lactic Acid) + HA (Hyaluronic Acid)
- Mechanism: Stimulates collagen synthesis + immediate hydration
- Specialization: Pores, volume, skin density
