Influencer and YouTuber hype
Many reviewers explicitly say they bought it because K-beauty YouTubers, Instagram 'beauty accounts', or word-of-mouth buzz made it a must-try, describing it as living up to 'the hype'.
Repeat/repurchase loyalty
A large number of reviews mention this being their 2nd, 3rd or 4th bottle, citing consistent coverage and staying power as reasons to keep repurchasing.
Reputation for high coverage with a light feel
Buyers who normally dislike heavy or cakey foundations purchased it because reviews promised department-store-level coverage without a thick after-look.
Sale pricing and cost-performance (CP)
Several reviewers specifically bought during Olive Young sales or with coupons, praising the price-to-performance ratio versus premium/department store foundations.
Wide shade range for Asian skin tones
Reviewers note the many numbered shades (19–23, warm/cool, .5 variants) as a reason to try it, hoping to find a closer match than other brands offer.
