Repurchase loyalty
Many reviewers explicitly state this is their 3rd, 5th, or 'countless' repurchase, calling it their go-to or holy grail acne patch they always restock.
Brand trust in COSRX
Customers who already used other COSRX acne patches (e.g., the Master Patch) bought this variant to compare or because they trust the brand's acne-care line.
Multiple sizes in one pack
Reviewers cite the variety of patch sizes (small to large oval) as a key reason to buy, since it covers different breakout stages and areas like the jawline or chin in one purchase.
Value for money
Several reviews describe the price as affordable or 'a benefit' relative to quantity, and some bought it opportunistically to reach free shipping thresholds.
Word-of-mouth and social proof
Buyers mention purchasing based on positive reviews or recommendations from friends, and some bought extra to gift or share with family members, including teens and children.
