Influencer and SNS recommendations
A large share of reviewers explicitly say they bought it because a YouTuber, makeup artist, or Instagram/TikTok influencer recommended it, indicating strong social-proof driven demand.
Repurchase/consumable restocking
Many reviewers are on their 4th-10th repurchase, treating the puff as a routine consumable that needs regular replacement for hygiene, and buy multi-packs to have spares on hand.
Price/value (CP value)
Reviewers frequently cite that it is cheaper than competitor puffs (e.g., Rosy Rosa) or was bought to reach a discount threshold, and praise getting 5 puffs per pack as good value.
Compatibility with existing cushion foundation
Buyers who already own an espoir Be Glow/Be Velvet cushion purchase this as a replacement puff, and others buy it specifically because it reportedly works well with other brands' cushions too.
Curiosity from positive reviews/ratings
Several reviewers say they bought it simply because of the high review volume or ratings they saw online, wanting to test if the hype was justified.
