Reputation for gentleness on sensitive skin
Many buyers specifically sought this out after reading reviews or hearing recommendations that it's safe for sensitive, rosacea-prone, or reactive skin.
AHA/exfoliation appeal without harshness
Consumers were drawn by the promise of chemical exfoliation (triple AHA) that is milder than typical acids, appealing to those who can't tolerate strong actives.
Brand trust from other Haruharu Wonder products
Several reviewers mention already loving the brand's toner or other items and buying the cleanser to complete the routine.
Influencer/video recommendations
A few reviews cite YouTube (e.g., Hyram) or video content as the reason they tried the product, sometimes as an alternative when a recommended version was out of stock.
Repeat purchase / loyalty
Extremely high repurchase rate is evident, with many customers on their 3rd, 4th, or 5th tube, showing it becomes a routine staple.
