Influencer and MUA recommendations
Many reviewers cite YouTubers, TikTokers, K-pop idol makeup artists, or Korean beauty salon staff as the reason they tried the product, describing it as a 'celebrated' or 'must-have' item.
Chronic smudging/panda-eye problems
A large share of buyers purchased specifically because their eyeliner, mascara, or eyebrow makeup habitually faded, smudged, or transferred due to watery eyes, oily lids, sweat, or humid climates.
Repurchase/loyalty
Numerous reviews explicitly state this is a repeat buy ('リピート', '재구매'), with some buying multiple bottles to share with family or as backup stock.
Word of mouth from friends
Several reviewers say a friend or colleague recommended the product after seeing its long-wear results firsthand.
Perceived value for money
Reviewers note the 10mL size lasts a long time with sparing use and call it good value or 'high quality but low price' relative to effectiveness.
