Brand trust and ingredient reputation
Many buyers already know Rejuran from in-clinic 'Rejuran Healer' injections and PDRN skincare, and purchase this ampoule as a trusted at-home extension of that treatment.
Influencer and social media hype
Several reviewers explicitly mention buying after seeing influencer videos or hearing 'hype' online about Rejuran/PDRN before trying it themselves.
Repurchase after positive first experience
A very high number of reviews are 2nd, 3rd, 4th or even 10th repurchases, often timed to Olive Young sales, indicating strong repeat-buyer behavior once trust is built.
Gifting, especially to mothers
Multiple reviewers bought the product as a gift for their mother or grandmother, citing the brand's premium/skincare-clinic reputation as gift-worthy.
Aftercare for microneedling/clinic treatments
Some consumers purchase it specifically to use after at-home microneedling or dermatologist visits to aid skin recovery.
