Price/value promotions
Many buyers explicitly bought or rebought the product because of frequent 1+1 (buy-one-get-one) deals that make the large 75+25 count pack extremely cheap per patch.
Brand trust in BringGreen
Reviewers cite prior good experience with BringGreen's tea tree/cica line and describe the brand as reliable for acne-prone skin, encouraging first-time and repeat purchases.
Repurchase loyalty
A very large share of reviews mention this being their 2nd-5th+ purchase, describing it as their 'go-to' or 'holy grail' spot patch they restock whenever supply runs low.
Variety of patch sizes in one sheet
Consumers valued that each sheet includes three or four sizes, letting them match patch size to pimple size without buying multiple products.
Gift and recommendation-driven trial
Several reviewers received it as a gift or bought it after hearing recommendations/seeing it used by family or online, then continued purchasing it themselves.
