Repurchase loyalty
A very high number of reviews explicitly state this is their 2nd, 3rd, or even 10th+ bottle, indicating strong repeat-purchase behavior and brand trust in VT.
Bundle value with Reedle Shot samples
Reviewers frequently cite the added mini essences and Reedle Shot 100 ampoules as a strong value incentive, especially during sales.
Word-of-mouth and influencer/social recommendations
Several buyers mention purchasing after seeing recommendations from Korean skincare influencers, friends, or platforms like Xiaohongjie (Red Note) and social media.
Sale/discount pricing
Multiple reviews note buying during promotional sales periods, suggesting price sensitivity and that discounts drive conversion for this set.
