Reputation for gentleness on sensitive/acne skin
Many buyers specifically sought it out after hearing it doesn't irritate sensitive, eczema-prone, or acne-prone skin, and purchased based on this reputation before even trying it.
Repurchase / loyalty
A very large share of reviews mention buying a 2nd, 3rd, or many more bottles, or having used it continuously for years, indicating high repeat-purchase behavior.
Price-to-value ratio
Reviewers repeatedly note it is affordable for the large 260ml volume, calling it good value ('가성비') that lasts for months.
Influencer/word-of-mouth recommendation
Several buyers mention trying it because a YouTuber or friend recommended it, or because it was 'famous for being mild' online.
Gifting
Multiple reviewers bought it as a gift for fathers, brothers, friends, or daughters, often citing its unscented, non-greasy, universally safe formula as gift-friendly.
