Influencer/YouTuber collaboration (Minsco)
Many reviewers explicitly say they bought the product because it was co-developed with or recommended by Korean YouTuber Minsco, especially chasing the viral 'Cortado' shade.
Pore-blurring reputation
Reviewers repeatedly mention buying it after hearing/seeing online that it has a strong 'pore blur' filter-like effect.
Repurchase / shade collecting
A large share of reviews are repeat buyers adding more shades ('3色目', 'bought 4 of these', 'completed the set'), indicating loyalty once tried.
Vegan/cochineal-free formula
Some buyers specifically cite it being carmine/cochineal-free as a reason for purchase, especially those with cochineal allergies.
Sale/discount timing
Several reviews mention buying during an Olive Young sale or global discount event, suggesting price promotions drive conversion.
