Viral/social media buzz
Many reviewers mention buying because of TikTok, Instagram influencer recommendations, or friends/family telling them about the 'hype,' explicitly saying they wanted to see what the popularity was about.
Repeat/repurchase loyalty
A very large share of reviews are explicit repurchases (2nd–10th bottle), often citing it as a 'holy grail' or staple they keep coming back to after trying other products.
Ingredient reputation (multi-molecular hyaluronic acid)
Several reviewers cite the '5 types of hyaluronic acid' or multi-molecular HA formulation as the reason for purchase, expecting deep, multi-layer hydration.
Suitability for sensitive/acne-prone skin
Buyers with sensitive or acne-prone skin specifically sought this out after reading it is fragrance-free and low-irritation, hoping to avoid breakouts common with other hydrating serums.
Price/promotions and bundle sets
Numerous reviews mention buying during Olive Young sales or as part of discounted skincare sets, indicating price sensitivity drives conversion.
