Celebrity/idol endorsement
A very large share of reviews explicitly cite buying the product because brand ambassador Sunghoon (ENHYPEN) or influencers like Mingyu (SEVENTEEN) used or promoted a shade, showing strong K-pop marketing pull.
Repeat purchase / brand loyalty
Many reviewers mention this being their 2nd, 3rd, or 5th tint from the line, or say they 'have it in every color,' indicating high repurchase intent once tried.
Packaging and limited editions
Seasonal or collaboration packaging (e.g., dot-pattern, spring editions) is frequently named as a purchase trigger independent of the color itself.
Bundled freebies
Buyers note the set's bonus mini lip pencil, gloss, or stickers as a value-add that motivated the purchase over single-item alternatives.
Price/promotion
Some shoppers mention buying during Olive Young sales or noting it was cheaper than buying the same product in Japan, reinforcing price-driven conversion.
