Repurchase/Brand Loyalty
A very large share of reviewers explicitly state this is a repeat purchase (2nd–10th+ time), often citing years of consistent use and calling it their 'holy grail' or 'go-to' eyeliner.
Reputation for Waterproof/Smudge-proof Performance
Many buyers purchased specifically because CLIO is known for waterproof eyeliners, especially for oily lids, watery eyes, sweat, and crying scenarios.
Influencer/Word-of-mouth Recommendation
Several reviewers mention being influenced by YouTubers, social media, friends, or in-store Olive Young staff recommendations to try the product.
Sale/Discount Timing
Multiple reviewers say they stock up or restock specifically during sales/coupon events, indicating price sensitivity despite loyalty.
Gifting
Some reviewers bought it as a gift for sisters, mothers, or daughters, citing its popularity and reliability as reasons for gifting.
