Viral popularity / word of mouth
Many reviewers, especially in Japanese and Korean, say they bought the product because it is 'famous' or trending on OliveYoung and social media, often after seeing repeated positive reviews.
Mung bean & pH-balanced ingredient story
Consumers were drawn to the mung bean extract and 'mildly acidic' (弱酸性) formulation, believing it would be gentler and better for skin barrier health than typical foam cleansers.
Repurchase after trying travel/mini size
Several buyers first tried a smaller size or the bundled 40mL mini before committing to the full 160mL, then repurchased once satisfied.
Recommendation from friends/family/influencers
Multiple reviews mention buying because a friend, spouse, daughter, or an online influencer recommended it, and some purchased extra units to give as gifts.
Value of the bundled set
The 160mL + 40mL set is seen as good value, with the mini size praised as ideal for travel or gym/concert use, reinforcing the purchase decision for cost-conscious buyers.
