Loyalty to the Nosca9 serum/ampoule line
A large share of buyers already use and love the FATION trouble serum or ampoule and bought the mask to pair with or supplement that routine.
Word-of-mouth and influencer recommendations
Several reviewers cite positive reviews, glowing recommendations from favorite influencers, or friends' suggestions as their reason for trying the product.
Reputation for calming acne-prone/sensitive skin
Buyers with recurring breakouts, redness, or sensitivity purchase it specifically for its known soothing reputation, often as an 'emergency' or 'insurance' item for flare-ups.
Repurchase due to past satisfaction
Many reviews explicitly state this is a 2nd, 5th, or 'millionth' repurchase, showing strong repeat-buy loyalty once tried.
Promotional pricing and value bundles
Multiple reviewers mention buying during sales (e.g., Big Sale, BIGBANG SALE) or because the per-sheet price was very affordable, prompting stockpiling.
