Influencer recommendation
Multiple reviews cite K-beauty personalities (specifically mentioned as 'Hyok') endorsing the product, which motivated purchase despite the premium price point.
Repurchase and brand loyalty
Several reviews explicitly state this is a repeat purchase, indicating strong product satisfaction and trust in the ISOI brand for acne-prone skin.
Targeted acne solution
Consumers bought it specifically to address recurring acne and pimples, either for themselves or family members (children, husbands with oily skin).
Deep cleansing reputation
The product's reputation for powerful pore-cleansing and sebum removal attracted consumers seeking more intensive than daily cleansers.
Availability and convenience
Some reviews note the product is not stocked in physical retail (OliveYoung stores), making online purchase the only option and driving e-commerce sales.
