Influencer/social media recommendation
Multiple reviewers cite Instagram, YouTube (e.g., a Korean beauty YouTuber comparing collagen content to Biodance), and TikTok virality as the reason they tried the product.
Comparison shopping vs. Biodance
Many buyers purchased after hearing this mask has higher collagen content or better value than the popular Biodance gel mask.
Bundle/gift promotions
A large number of reviews mention receiving the mask as a free gift-with-purchase or buying it as part of a discounted set with ampoules/serums, which drove trial.
Repurchase loyalty
Very frequent mentions of second, third, or 'multiple' repurchases, indicating strong repeat-buy behavior once tried.
Ingredient/collagen reputation
Some buyers specifically chose it for its marketed high collagen percentage and anti-wrinkle/firming claims.
