Sale/discount pricing
A very large share of reviewers explicitly say they bought during Olive Young sales or bulk deals, citing the low per-sheet cost (around $1-3) as a key reason to purchase or stock up.
Gift purchases
Many buyers purchased the mask as a gift for mothers, grandmothers, or friends, often noting the recipient enjoyed it and prompting the buyer's own repeat purchase.
Brand trust / Dr.G reputation
Reviewers frequently mention buying because they already trust or use other Dr.G Black Snail line products (cream, serum) and wanted to complete the routine or try the matching mask.
Word-of-mouth and influencer recommendation
Several reviews cite recommendations from friends or influencers (e.g., a mentioned KOL) as the reason for trying the product for the first time.
Repurchase due to prior satisfaction
A notable portion of reviews are repeat buyers ('second/third order', 'always restocking'), indicating strong loyalty once tried.
