Pore-minimizing reputation
Consumers frequently cite SNS/social media visibility of the product's pore-reduction claim and direct influence from beauty influencers and platforms like TikTok and Instagram as the primary driver for initial purchase.
Brand line loyalty and bundle value
Many buyers already owned other Numbuzin No.3 products (toner, sheet mask) and purchased the serum as a complementary step or were attracted by bundle deals and promotional pricing (1+1 offers).
Reformulation appeal
The updated formula's lighter, faster-absorbing texture and perceived ingredient enhancement prompted both lapsed and curious customers to repurchase or trial the refreshed version.
Makeup base/prep interest
Several consumers specifically purchased for use before makeup application to improve skin texture, smoothness, and foundation adherence on rough or oily skin.
Price and promotional discounts
Significant mention of attractive pricing, sales events, and bundle deals ('got it with good deal') as decisive factors for purchase timing and cart conversion.
