Yes per session: Rejuran Eye is ₩119,000 (≈ $85) while under-eye filler starts at ₩169,000 (≈ $121) and reaches ₩349,000 (≈ $249) for Juvederm on Kind Global Clinic Myeongdong's published menu — but a full Rejuran course takes 3 to 4 sessions, so the totals converge.
The honest answer to whether under-eye Rejuran is cheaper than under-eye filler has 2 layers, and Kind Global Clinic Myeongdong's published menu lets you read both. Layer 1 is the session price: Rejuran Eye is listed at ₩119,000 (≈ $85), while under-eye filler is priced by brand — ₩169,000 (≈ $121) for Mihee, ₩219,000 (≈ $156) for Neuramis, ₩289,000 (≈ $206) for Belotero and ₩349,000 (≈ $249) for Juvederm, each per 1cc. On that layer, under-eye Rejuran is the cheaper line at every brand tier.
Layer 2 is the course: Rejuran Eye is a polynucleotide (PN) skin-quality treatment that works cumulatively, so the standard protocol is 3 to 4 sessions spaced 2 to 4 weeks apart, while a filler correction is typically completed in 1 session and holds for 12 months or longer. Multiply the session counts and the two totals sit much closer than the single-session gap suggests. More important than either number: the two treatments fix different under-eye problems. Rejuran addresses crepey texture, fine lines and thin skin quality; filler restores volume in a tear-trough hollow. The 15 to 20 minute co-director consultation exists to diagnose which one your under-eye actually needs — and both carry the same KRW price for international and Korean patients.
