Brand and ingredient reputation
Many buyers cite trust in Round Lab's natural, gentle formulation and its strong reputation built from other products in the line (toner, sunscreen), leading them to try the mask.
Positive reviews and hype/word-of-mouth
Reviewers frequently mention purchasing after seeing high ratings, YouTuber recommendations, or hearing about the 'cult favorite' status of the Dokdo line.
Repurchase / stocking up during sales
A large share of reviews are repeat buyers who restock in bulk (4+ boxes, value sets, 20+ pieces) especially during Olive Young or Korea sale events.
Suitability for sensitive/acne-prone skin
Buyers with sensitive, combination, or acne-prone skin specifically purchased this mask because it is fragrance-free and known not to irritate or cause breakouts.
Gifting
Several reviewers bought multiple units specifically to give as gifts to friends, family, or nieces, citing the mild formula as gift-safe.
