Signature scent reputation
Many buyers explicitly purchased for the 'Tender Bloom' or 'Warm Petal' scent, often after smelling it in the matching shampoo/treatment or receiving a sample/mini size.
Repurchase/loyalty
Numerous reviewers state this is their second, third, or repeated purchase, citing consistent results and 'won't buy anything else' sentiment.
K-beauty/brand trust
Several reviewers note UNOVE is 'already famous in Korea' or that they buy the 'full line' after trying one product, suggesting brand halo effect drives purchase.
Gifting
Reviewers mention buying it as a gift for family members (mom, brother) or receiving it as a complimentary sample that converted into a full-size purchase.
Idol/influencer association
At least one reviewer references buying it because of a K-pop idol (Mingyu) connection, indicating some purchases are influencer/fandom driven.
