Repeat purchase / collector behavior
Many reviewers mention owning their 2nd, 3rd, or 5th tube in different shades, citing consistent quality as the reason for repurchasing rather than trying other brands.
Gift-with-purchase bonuses
A notable share of buyers say they purchased primarily for the bundled pouch, keyring, or mini lip pencil rather than the lip tint itself, though most ended up liking the product too.
Reputation for being non-irritating
Several reviewers explicitly switched from other Korean tint brands (e.g., rom&nd) after experiencing lip peeling, choosing espoir because word-of-mouth said it doesn't cause the same irritation.
Influencer and social media recommendation
Multiple reviews mention discovering the product via YouTubers or Instagram before purchasing, suggesting influencer marketing is an effective sales channel.
Sale and discount pricing
A number of buyers note they purchased during a sale or discount event, with some saying they would hesitate to buy at full price.
