What we found
Based on how this product compares to others in the cleansers category, cross-referenced against retailer listings and market data.
Strengths
- + The namesake ingredient is real: onion extract at a retailer-disclosed 50,000 ppm and position 4 in the ingredient list — the opposite of a token dose
- + Fragrance-free and essential-oil-free on the ingredient list, unusual in the blemish-foam set
- + Strong Korean reception: 4.56 across 1,338 Hwahae reviews, with 'Cleanses Well' (362) and 'Not Irritating' (287) leading the patterns
- + Budget price — $13.64 for 150 mL ($0.091/mL), cross-checked against the Korean MSRP ($13.60)
Worth knowing
- - It is an alkaline potassium-soap foam, buffered but still soap-led, with sodium C14-16 olefin sulfonate adding cleansing strength — not a low-pH cleanser
- - 'Feels Tight' is a real pattern (219 mentions); dry skin should expect a tight finish even though most reviewers report no deep dryness
- - The onion/brightening actives (tranexamic acid, sodium ascorbyl phosphate) sit in the tail — in a 60-second rinse-off they are 'contains' ingredients, not scar or spot treatment
- - The ingredient list has quietly changed over time (37 → 41 ingredients) without a brand announcement
