Influencer/YouTuber recommendations
Many reviewers explicitly say they bought it after seeing Korean, Japanese, or Western beauty YouTubers and Instagram influencers recommend it as a makeup-prep essential.
Viral/word-of-mouth hype
Reviewers repeatedly mention it 'went viral,' is frequently sold out, or was recommended by friends/makeup artists in Korea, prompting curiosity purchases.
Repurchase loyalty
A large number of reviews are 2nd, 3rd, or more repurchases, citing consistent makeup-hold results as the reason to buy again.
Bundled free cream
The included rose smoothing cream sample is frequently cited as adding perceived value and a reason to try the set.
Sale/discount pricing
Several buyers say they purchased specifically because it was on sale, since they perceive the regular price as high for the volume.
