Repurchase/holy grail status
An extremely high share of reviews explicitly state this is a 3rd-5th+ or even lifetime repurchase, showing strong loyalty and predictable reorder demand.
Refill format cost/eco savings
Buyers who already own the compact case buy the refill specifically because it's cheaper and reduces plastic waste versus buying the full case again.
Brand reputation and reviews
Several reviewers bought it after hearing raves from friends, YouTubers, or because 'Hera' is a known premium/luxury Korean brand, including mentions of ambassador Felix driving purchase interest.
Long-lasting, no-touchup wear
Reviewers cite all-day wear through heat, sweat, and exercise without smudging as a key reason for choosing/repurchasing this over other cushions.
Wide, accurate shade range
Multiple reviewers note finding a rare perfect shade match (e.g., 17N, 21N, 25N variants), which drives both initial purchase and repeat buying of that specific shade.
