Brand reputation and Picasso trust
Many buyers explicitly cite Picasso brand loyalty as a purchasing driver, trusting the brand's makeup brush care expertise based on prior positive experiences with other Picasso products.
Value proposition over alternatives
Consumers frequently compare it favorably to 100-yen shop products, liquid cleansers, and competitor soaps like Filli, citing the large bar size and superior performance as justifying the higher upfront cost.
Recommendation and word-of-mouth
Several reviews mention purchasing after hearing great reviews or receiving it as a gift before repurchasing, indicating strong organic advocacy and try-before-buy conversion.
Efficiency and time-saving appeal
Buyers emphasize that it cuts brush-cleaning time in half compared to previous products, making it attractive to frequent users (e.g., daily puff washers, makeup artists).
Social proof and influencer visibility
Mentions of using it 'constantly' and multiple repurchases suggest this product has strong social and online visibility driving trial among beauty-conscious consumers.
