Brand/line loyalty from cushion foundation
Many reviewers say they already love JSM's cushion foundation and wanted a matching blush, buying based on trust in the brand's texture and quality.
Viral/word-of-mouth buzz
Several Japanese reviewers mention buying because the product was 'viral' (バズっていて) or had good word-of-mouth reviews online.
Dewy glow trend appeal
Consumers cite wanting a 'glass skin' or dewy glow look that powder blushes can't achieve, positioning this as a trend-driven purchase.
Gift or sample-to-full-size conversion
Multiple reviewers received a mini/sample with a cushion foundation purchase, loved it, and then bought the full-size product or additional shades.
Shade collecting/repurchase
A notable share of reviewers report owning 3, 5, or even 6 colors, buying additional shades after a positive first experience.
