Ingredient/brand reputation for barrier repair
Many buyers cite the ceramide formulation and ILLIYOON's reputation (backed by Amorepacific) for treating eczema, atopic dermatitis, and sensitive/dry skin as their main reason for trying it.
Influencer and word-of-mouth recommendation
Several Japanese and English reviewers specifically mention purchasing after seeing an influencer recommendation or a friend's suggestion.
Repurchase / loyalty
A very large share of reviews explicitly state this is their 2nd, 3rd, or 10th+ repurchase, indicating strong brand loyalty and repeat B2C demand.
Value for large volume (600mL+128mL bundle)
Buyers frequently mention the large size and bundled travel tube as good value ('cospa'), reducing per-use cost and shipping frequency, especially appealing versus buying single smaller bottles in Korea.
Fragrance-free formulation for sensitive users
Many purchasers specifically sought an unscented lotion for sensitive skin, children, or family members with eczema/psoriasis, and chose this product for that reason.
