Word-of-mouth / viral popularity
Many reviewers say they bought it because it is a famous or frequently recommended item ('everyone recommends it', 'heard it's famous so I tried it'), reflecting strong organic buzz.
Bundled gift set value
Numerous reviews mention buying the set specifically for the included mini lip tint or gloss, viewing it as a good-value bundle, sometimes for gifting.
Repurchase after losing or running out
A large share of reviews are repeat purchases ('bought again after losing it', '2nd/3rd tube'), indicating high loyalty once a matching shade is found.
Influencer/celebrity association
Some buyers cite YouTube tutorials or a celebrity's use (e.g., idol lip looks) as their trigger to purchase specific shades.
Wide, versatile shade range
Reviewers frequently mention wanting to collect multiple colors because the range suits various skin tones (cool/warm) and pairs well with many lipsticks/tints.
