“How long will it last?” deserves a better answer than the brochure number. Filler longevity is a function of product class, facial area and your own metabolism. The retouch strategy matters as much as the first session. Ever Dermatology in Apgujeong maps the realistic numbers and the maintenance rhythm that keeps results continuous instead of cyclical.
Longevity by area: the honest table
High-movement areas burn filler faster: lips commonly hold 6-12 months, nasolabial folds 9-15. Low-movement, deep-on-bone placements last longest: chin and jawline 12-18 months, often beyond, and cheeks 12-18. Under-eye tear troughs are the quiet outlier at 12 months or more, because the area barely moves. Firm high-cohesivity gels outlast soft ones, and your personal rate sits within these ranges, discovered by your own first cycle.
What speeds the clock
Metabolism varies person to person; athletes and high-metabolism patients routinely report shorter spans. Repeated heat exposure (frequent saunas), high-dose exercise, and massage-heavy skincare on treated areas accelerate breakdown. Hyaluronidase obviously ends things immediately. None of these is a reason to avoid living; treat them as inputs for planning your personal retouch interval.
The smart retouch rhythm
The wasteful pattern is letting filler vanish completely, then rebuilding from zero and paying full volume each round. The efficient pattern is a retouch at roughly 70-80% remaining, topping up smaller amounts that maintain a steady look. Practically, that means a check at 9-12 months for most areas. Clinics tracking you with photos can see fading you cannot, and a standing annual review converts filler from repeated purchases into a managed state.
Ever Dermatology schedules retouch reviews by area and personal response rather than fixed packages, consulting international patients in Apgujeong. Note your own dates and photos from session one; the first cycle is the best longevity data you will get.
