Word-of-mouth / influencer & peer recommendation
Many reviewers cite hearing about the product from Korean friends, social media, or 'everyone recommends it' before purchasing, especially for the inner-dry skin claim.
Repurchase / loyalty
A very large share of reviews explicitly say this is a 2nd, 3rd, 4th, or many-times repeat purchase, with some users noting 5+ years or 10+ bottles consumed.
Price/value and large size
Reviewers frequently mention the twin-bottle 75ml x2 format is generous and cost-effective compared to competitors like Torriden, especially when bought on sale/mega-discount events.
Ingredient reputation (hyaluronic acid, ceramide, cica)
Buyers say they trust the hyaluronic acid formulation and Korean-brand reputation for hydration performance, with some noting it ranks #1 in Korean skincare rankings.
Seasonal/skin-condition need
Many purchased specifically to address dryness during winter or 'inner dry' skin flare-ups in summer air conditioning, or after sun/boat exposure.
