Why consumers buy
Line extension from masks/pads
Many buyers already loved MEDIHEAL's Madecassoside sheet masks or toner pads and purchased the serum to continue the same skincare line.
Influencer/YouTuber recommendations
Several Japanese and Korean reviewers cite YouTubers, idols (e.g., LE SSERAFIM's Eunchae), or 'red book' (Xiaohongshu) recommendations as the reason for purchase.
Reputation as a top-seller
Reviewers reference the product's status as Olive Young's #1 mask/skincare category bestseller for 13 consecutive years, boosting trust and purchase decisions.
Ingredient reputation (madecassoside/CICA)
Buyers with redness-prone or sensitive skin sought out the product specifically for its madecassoside/CICA soothing ingredient reputation.
Sale/bundle promotions
Many purchases were driven by Olive Young mega sales, bundle deals with masks, or lower prices than buying in Korea directly.
