Seasonal/sun-care need
A large cluster of reviews, especially from Japanese buyers, mention purchasing specifically for summer UV exposure or after sunburn, using vitamin C as a soothing/brightening aftercare step.
Positive word-of-mouth and reviews
Several buyers state they purchased because of good reviews or friend recommendations before even trying the product themselves.
Sale/price promotions
Numerous reviewers mention buying in bulk during Olive Young sales or because it was cheaper than mega-sale alternatives, indicating high price sensitivity and promo-driven purchasing.
Gifting
A few reviewers bought the mask as a gift for sisters, nieces, or friends, citing its gentle, hydrating reputation as suitable for dry or sensitive-skinned recipients.
