Travel convenience
Extremely frequently cited reason for purchase is the compact, no-liquid-restriction format that is easy to pack for flights and trips.
Repurchase / repeat loyalty
A large share of reviewers explicitly state this is their 2nd, 3rd, or many-times repurchase, some noting years of continuous use.
Word-of-mouth and social media hype
Several reviewers mention buying because of TikTok, Instagram, friend recommendations, or seeing it as a popular 'must-buy when visiting Korea' Olive Young item.
Sale/price promotion
Multiple reviewers say they bought in bulk during Olive Young sales, Black Friday, or bundle deals because of attractive pricing.
Waterproof makeup removal reputation
Many buyers purchased specifically hoping it could tackle stubborn waterproof mascara and lip tint that other removers failed to remove.
