Device companion purchase
Most reviewers bought the gel specifically to use with medicube devices (Booster Pro, AGE-R, High Focus Shot, Ussera), often purchasing gel and device together or as a required accessory.
Large size / value for money
The 300ml tube size is repeatedly cited as a major buying driver, with reviewers noting it lasts for months and offers better value than smaller ultrasonic gels.
Repurchase / brand loyalty
Many reviewers explicitly state this is their 2nd or 3rd repurchase, citing consistent performance and trust in the medicube brand.
PDRN/peptide ingredient reputation
Several reviewers mention buying because of the PDRN and polypeptide content, associating it with skin repair, elasticity, and anti-aging benefits.
Promotions and discounts
A number of buyers mention purchasing during sales or promotional pricing on Olive Young, suggesting price sensitivity influences purchase timing.
