Value of double pack
Many reviewers specifically cite the 1+1/double-pack pricing as the reason for purchase, calling it cheaper than buying single tubes at drugstores or elsewhere.
Brand loyalty / repeat purchase
A large share of reviewers say they have repurchased multiple times (2nd, 3rd, 4th time) after finishing the original yellow Torriden lip product, showing strong brand trust.
Curiosity comparing to yellow 'solid-in' version
Many buyers purchased specifically to compare this pink collagen essence against Torriden's popular yellow lip balm, often ending up preferring one over the other.
Ingredient reputation (low molecular collagen)
Several reviewers mention being drawn in by the collagen ingredient claim and its promise of plumping/elasticity benefits.
Gift purchases
A few reviews mention buying it as a gift for friends or family members who also ended up liking it.
