Brand/line trust from tea tree sheet masks
Many buyers purchased because they already loved Mediheal's tea tree sheet masks and wanted the ampoule version of the same soothing formula.
Acne and irritation management
A large share of purchases were driven by a need to calm hormonal or stress-triggered acne, post-mask irritation, or heat-related flare-ups.
Word-of-mouth and influencer/staff recommendation
Several reviewers cite YouTube influencers, in-store Olive Young staff, or friends' recommendations as the trigger for trying the product.
Repurchase / holy-grail status
Multiple reviewers are on their 3rd-4th+ bottle, describing it as a staple they feel anxious without, indicating strong loyalty.
Price/value and promotions
Some buyers cite good value or sale pricing as a reason to buy, though a few others found it expensive for the volume.
