COSRX 5 PDRN B5 Vital Soothing Toner: PDRN in the Toner Format

COSRX took the PDRN trend that REJURAN popularized and built it into a daily toner format. This 5 PDRN B5 Vital Soothing Toner pairs PDRN (polydeoxyribonucleotide, the salmon-DNA-derived skin regenerator) with panthenol (vitamin B5, the ceramide-adjacent barrier soother). The combination is smart: PDRN drives regeneration signaling, B5 supports barrier calming. Together they give a daily-use toner that actually does work beyond hydration.

At $51 for 280ml, this is higher-priced than COSRX's classic toners but lower than REJURAN's PDRN-focused line. It positions the PDRN category for users who want to try the ingredient daily without committing to REJURAN pricing.

What It Does

PDRN supports skin cell regeneration signaling and collagen production. Panthenol provides immediate barrier soothing and hydration. The combination works well on stressed, irritated, or post-procedure skin. Lightweight toner format layers under anything in the routine.
