Ingredient Innovation (PDRN)
Multiple reviews specifically mention purchasing because of the rare PDRN (Polydeoxyribonucleotide, salmon-derived) ingredient, which is positioned as a scientific and novel approach to lash care versus conventional formulas.
Influencer & Social Recommendation
Several consumers explicitly state they purchased after seeing influencers use the product or reading positive online comments, indicating strong word-of-mouth and social proof driving acquisition.
Brand Trust & Repurchase Loyalty
Numerous reviews indicate second, third, or fourth purchases, with consumers citing trust in the SKINFOOD brand and satisfaction with previous experiences, particularly with other product lines like eyebrow products.
Sensitivity & Safety Concerns
Buyers with sensitive eyes or history of irritation from competing products (The Ordinary, Japanese brands, Latisse, RevitaLash) specifically chose this serum for its documented non-irritating profile.
Price Point & Sales Promotions
Multiple reviews mention purchasing during sales/promotional periods (e.g., 1,314 KRW mentions), indicating price sensitivity but willingness to buy at discounted rates on platforms like Olive Young and Coupang.
