Repurchase and brand loyalty
An unusually high share of reviews explicitly state this is a repeat purchase or that the buyer has bought it multiple times, often citing Torriden as a trusted go-to brand for hydration.
Reputation and word-of-mouth hype
Several reviewers mention buying because of its bestseller status or reputation ('hype', ranking on Korean sales charts, seeing it recommended), sometimes noting it's now even sold in Japanese convenience stores.
Sale/discount driven purchases
Many Japanese and other international reviewers say they buy specifically during sales or coupon events because the product is otherwise considered a bit pricey outside Korea.
Sensitive/problem skin suitability
Buyers with sensitive, acne-prone, or post-procedure (laser, sunburn) skin purchased it because it's marketed and reported as low-irritant and calming.
Gifting
A handful of reviewers bought the mask as a farewell or travel gift for colleagues/family, citing its safe, crowd-pleasing hydration profile.
