Value of the 2-for-1 bundle
An overwhelming number of reviewers cite the '1+1' set as excellent value, often mentioning they stock up or buy multiples specifically because of the bundled pricing and periodic coupons/discounts.
COSRX and Cica ingredient reputation
Many buyers trust the COSRX brand from prior positive experience with other lines and specifically sought out the Cica ingredient for its soothing, calming reputation for sensitive or irritated skin.
Gifting for family with sensitive skin
A notable share of purchases were made as gifts for parents, spouses, siblings, or friends described as having sensitive, dry, or acne-prone skin, suggesting the product is seen as a 'safe' universal gift cleanser.
Word-of-mouth and social/influencer recommendation
Several reviewers mention trying it after seeing it recommended on YouTube, SNS, or by friends, or after receiving a sample size that convinced them to buy the full set.
Repeat purchase / loyalty
A very large portion of reviews are explicit repurchases, with some customers noting they have used the product for 1-4+ years or bought it '4 times', '5th bottle', etc., indicating strong retention once tried.
