Brand/ingredient reputation (Centella)
Many buyers purchased because they already loved SKIN1004's Centella ampoule/toner pad line and wanted the same formula in mask form.
Repeat purchase / restocking on sale
A large share of reviews are explicit repurchases, often timed to Olive Young or Qoo10 sale discounts and multi-item sets.
Received as free gift/sample first
Several reviewers first tried the mask as a giveaway or set bonus and then bought it again after liking it.
Sensitive/irritated skin needs
Buyers with sensitive, redness-prone, acne-prone, or actives-irritated (retinol/tretinoin) skin sought this out specifically for its calming reputation.
Social media / word of mouth
Some reviewers mention discovering the product via SNS or general popularity/trend before purchase.
