Brand trust and loyalty
Many reviewers say they buy because they already love and trust the Bioheal BOH line, having used the brand's cream, toner, or eye cream previously and finding the brand 'never fails.'
Repeat purchase / reorder
A very high number of reviews explicitly state this is their 2nd, 3rd, or 4th+ repurchase (リピ, 回購), suggesting strong retention once tried.
Value for large pack size
Reviewers frequently note the 60-count box is affordable and 'lasts ages,' making it feel like good value compared to smaller patch sets from other brands.
Influencer/word-of-mouth recommendation
Several buyers mention trying the product after seeing YouTube reviews or recommendations from other users praising the adhesion and transparency feature.
Gifting
Some reviewers purchased the product as a gift for mothers or daughters dealing with dark circles or mature skin concerns.
