Set value/bundling
Many buyers cite the bundle of a full-size cream, two travel minis, and three sheet masks at a price seen as much better than buying components separately or during sale events.
Repeat purchase/brand loyalty
A large share of reviews are from repurchasers, some noting they are on their 3rd-10th tube and have used the Centellian24 Madeca line for years.
Word-of-mouth and influencer/social media buzz
Several reviewers mention buying after seeing it recommended on TikTok, by Korean Instagram influencers, or through friend/family recommendations.
Reputation for sensitive/acne-prone skin
Buyers with sensitive, irritated, or acne-prone skin purchased based on the product's reputation for being gentle and soothing, sometimes as an alternative to steroid creams or other moisturizers that caused breakouts.
Gifting
Multiple reviewers bought the set as a gift for parents (mom/dad) due to its reputation and travel-friendly mini sizes.
