Influencer/YouTube recommendations
Multiple reviewers say they bought after seeing K-beauty influencers, idols (e.g., Single's Inferno's Siyeon), or YouTube tutorials feature specific shades.
Set/bundle value
Many buyers chose the set specifically because it includes a mini blush and brush at a price seen as cheaper than buying items separately.
Repeat purchase / shade collecting
A notable share of reviews are repurchases or additions to a growing shade collection, citing loyalty to the Glint highlighter formula.
Popularity/social proof
Reviewers frequently mention buying because the product is 'the most popular highlighter' on Olive Young or trending on social media.
Undertone versatility
Some shoppers bought specific shades (warm vs cool) after research to match their personal undertone (yellow/blue base).
