Reputation of the VT Reedle Shot serum line
Many buyers purchased specifically because they already trust or are curious about the hyped VT Reedle Shot microneedle serum and wanted an easier, mask-format way to use it.
Repurchase/loyalty
A very large share of reviews are 2nd, 3rd, or even 10th repurchases, indicating strong repeat-buy behavior and brand loyalty to the VT line.
Sale/promotion pricing
Numerous reviewers explicitly say they bought because it was on sale or a 'great deal,' and several note they wait for discounts due to normally higher pricing.
Recommendations (influencer/friend/word-of-mouth)
Several reviewers cite Instagram, YouTube, or friends' recommendations, and Korean reviewers note it is a currently popular/trending product in Korea.
Convenience over buying full-size serum
Buyers like that the mask lets them try or use the Reedle Shot effect without purchasing a full bottle of serum, and appreciate the travel-friendly single-use format.
