| Verdict | COSRX's brightening pivot on the cult Snail line — 80% snail secretion filtrate plus niacinamide and a probiotic complex in a dual-phase essence that delivers visible glow on top of the line's signature plumping. The 'radiance' positioning is real: this is the snail essence to reach for if dullness is your concern as much as hydration. Same brand discipline that made the original 96 Mucin Power Essence sell every 25 seconds globally — applied to the dullness side of the equation. Particularly good for mature skin that wants the snail benefits with a brightening edge. | LG's answer to SK-II Pitera — a naturally fermented essence that takes 50+ days in controlled fermentation tanks. The glow is real, the texture is water-thin, and the ferment is genuinely different from galactomyces. If SK-II is the J-beauty first treatment essence, Su:m37° is the K-beauty equivalent. |
