Reputation for gentleness
Many buyers purchased after hearing it was one of the gentlest cleansers available, especially suited for sensitive or barrier-damaged skin.
Repurchase loyalty
A large number of reviewers explicitly state this is their 2nd-6th bottle, showing strong repeat-purchase behavior driving continued sales.
Gifting
Frequently bought as gifts for mothers, sisters, husbands, friends, and teens, often to introduce them to K-beauty.
Influencer/word-of-mouth recommendation
At least one reviewer cited buying after seeing it recommended by a known beauty influencer (James Welsh), and others mention friends recommending it.
Affordable price point
Several reviews highlight it as a high-quality product at an accessible price compared to pricier Western cleansers like La Roche-Posay or Fresh Soy Cleanser.
