Repurchase & Loyalty
The majority of reviews explicitly mention repeat purchases over months or years, with many describing it as a non-negotiable staple ('cannot live without it'). Customers stock up during sales and view it as their go-to first step.
Influencer & Social Recommendations
Several reviews cite discovery via Instagram, TikTok influencers (e.g., Kazuha as ETUDE muse), and word-of-mouth from friends or family members, driving trial and conversion.
Value & Bundle Packaging
The 1+1 set (700mL total for the price) is explicitly praised as 'great value' and 'economical.' Buyers appreciate the refill pouch, which enables generous, guilt-free use without waste concerns.
Sensitive Skin Need
Customers with eczema, psoriasis, atopic dermatitis, fungal acne, or post-barrier-damage skin actively seek this product after reading reviews mentioning its gentle, non-irritating formula and pH-balancing properties.
Comparison to Premium Alternatives
Several customers note switching from or comparing to higher-priced options (e.g., Amorepacific lines, Amazon US pricing at $20/180mL), viewing this as a superior cost-per-volume alternative.
