Repeat purchase / brand loyalty
Many reviewers state this is their 2nd-4th+ bottle and that they always return to Abib's Bifida/Jericho Rose line, often specifically for the paired cream as much as the serum.
Bundle/value deal
The 50mL+30mL set with a bonus cream or sample is repeatedly cited as 'a great deal' or bought during a sale, making the set attractive for price-conscious buyers.
Influencer/YouTube recommendation
Several Korean and Japanese reviewers mention buying after seeing it recommended by YouTubers or influencers, including tips on pairing it with an ampoule or beauty device.
Ingredient reputation (Bifida/resurrection plant)
Buyers cite the 'bifida complex' and '복활초' (resurrection plant) ingredient story as a reason to trust its soothing and moisture-retention claims, especially compared to other bifida serums like Manyo.
Gift purchase
Several reviews mention buying the set as a gift (for a mother, partner, or friend) due to its attractive packaging and reputable brand status.
