In summary: Juvelook and Rejuran are both Korean injectable skin quality treatments but with different active molecules and mechanisms: Rejuran uses polynucleotides (PN/PDRN derived from salmon DNA) that repair cellular damage and stimulate DNA-level regeneration, making it ideal for skin repair, acne scars, and very sensitive skin; Juvelook combines PDLLA with hyaluronic acid to stimulate collagen structurally and is the only option that can safely treat the periocular area (crow's feet, eyelids, dark circles). Rejuran is preferred for damaged or sensitive skin needing repair; Juvelook is preferred when the goal is structural collagen stimulation in all facial areas including the eye contour — and both can be combined in a complementary protocol.
South Korea has been exporting innovation in aesthetic medicine for years. Two of its most influential products in the Latin American market are Juvelook and Rejuran — both injectable, both focused on improving skin quality, both with solid clinical backing. But they are not interchangeable.
They are good for different things.
