Word-of-mouth and rave reviews
Many buyers explicitly say they purchased after reading glowing reviews or hearing it was popular in Korea, often calling it a 'holy grail' before even trying it.
Influencer and social media recommendations
Several reviewers mention discovering the product via TikTok, YouTubers, or friends' recommendations, describing it as an 'online recommendation' purchase.
Cheaper alternative to premium Western brands
At least one long-time user switched from SkinCeuticals Triple Lipid Restore because it was too expensive to keep repurchasing, finding this a comparable value substitute.
Targeted for compromised or sensitive skin barrier
Buyers with eczema, psoriasis, rosacea, or skin damaged by retinol/tretinoin sought this out specifically for barrier repair, often after trying multiple other products.
Repeat purchase / loyalty
A large number of reviews are explicit repurchases (2nd, 3rd, up to 10th tube), indicating strong repeat-buy behavior once tried.
