Brand/ampoule halo effect
Many buyers already use and love WELLAGE's Real Hyaluronic Ampoule or serum and purchased the mask to try the same active ingredient in sheet form, often planning to buy the ampoule next if they liked the mask.
Sales and discount pricing
A large share of reviewers say they buy exclusively during Olive Young sales or when the price is discounted, stocking up in bulk at that time.
Influencer and SNS recommendations
Several reviewers cite Instagram, Threads, or Korean influencers/celebrities recommending the mask as the reason for their first purchase.
Repeat purchase / loyalty
A notable number of reviews explicitly mention this being their 2nd, 5th, or 'countless' repurchase, calling it their favorite or holy-grail hydrating mask.
Word of mouth and gifting
Some purchases were prompted by a friend's recommendation or after receiving the mask as a gift from a friend and liking the result.
