Repeat brand loyalty
Many reviewers explicitly state this is their 2nd, 3rd, 5th, or even 'almost every' Lummir palette they own, citing consistent formula quality as the reason for repurchasing.
Word-of-mouth and hype
Several buyers say they purchased because 'everyone has it' or after seeing many positive reviews/rankings, indicating strong social proof driving trial.
Influencer and tutorial recommendations
Specific mentions of YouTubers/creators (e.g., bbomni, Iseul) and makeup tutorial videos influenced purchase decisions for shade selection and technique.
Personal color (undertone) matching
A large share of Korean/Japanese reviewers buy based on whether the palette suits their diagnosed 'personal color' (warm spring, cool summer/winter), often referencing specific shade numbers as best for their tone.
Sales, coupons and restocks
Reviewers mention buying during promotions/coupons or after waiting through long sold-out periods, showing price sensitivity and pent-up demand.
