Strong word-of-mouth and repeat purchase
Many buyers say they tried a sample or gift size first, loved it, and then purchased the full-size or repurchased multiple bottles over months or years.
Ingredient reputation (propolis/honey)
Reviewers frequently cite propolis's soothing, antioxidant, and skin-barrier benefits as a key reason for buying, especially those with dry or sensitive skin.
Value for money / bundle promotions
Several reviews highlight the large 280ml size and discounted bundle sets (with 150ml) as offering excellent value compared to competitor toners.
Influencer and community recommendation
Some buyers mention purchasing because a YouTuber, blogger, or SNS influencer recommended it, or because it had high ratings/popularity on platforms like Oliveyoung.
Brand trust from other COSRX products
Customers who already use COSRX's propolis ampoule, serum, or cream often buy the toner to complete the line, expecting similar soothing and hydrating effects.
