Brand loyalty / prior BOH product satisfaction
Many buyers say they already use and love other BIOHEAL BOH or Probioderm line products (eye cream, ampoules) and purchased the sun cream expecting the same quality.
1+1 / double-pack value pricing
The 1+1 set format and frequent Olive Young sales/coupons are repeatedly cited as reasons for purchase, with buyers calling it 'great value' and stocking up during promotions.
Influencer and word-of-mouth recommendation
Several reviewers mention buying because a YouTuber, friend, or social media trend recommended it, describing it as 'the hot commodity in Korea right now'.
Skincare-ingredient reputation
Buyers were drawn by the inclusion of collagen, probiotics, and peptides, hoping for anti-aging and hydrating benefits beyond basic sun protection.
Repurchase after positive first use
A large share of reviews explicitly state this is a 2nd, 3rd, or even 10th repurchase, indicating strong retention once tried.
