COSRX 5 PDRN B5 Vital Soothing Toner is a lightweight, hydrating toner formulated to help calm and rejuvenate the skin. With a volume of 9.46 fluid ounces, this Korean skin care product combines salmon DNA (PDRN), Centella asiatica extract, Lactobacillus ferment filtrate (Lactobacillus PDRN), and panthenol (vitamin B5) to support skin recovery and moisture balance. The PDRN component derived from salmon DNA is known for its skin-conditioning properties that may aid in soothing stressed or irritated skin, while panthenol acts as a humectant to attract and retain hydration. Centella asiatica is included for its traditionally recognized calming effects, and the Lactobacillus ingredient contributes to a balanced skin microbiome. This toner has a watery, non-sticky texture that absorbs quickly without leaving residue, making it suitable for layering in a multi-step routine. It is designed for those seeking a gentle, everyday toner that can help reduce the appearance of redness and support skin barrier function. The formulation is free from drying alcohols, artificial fragrances, and parabens, catering to sensitive, combination, or dehydrated skin types. Regular use may help prepare the skin to better absorb subsequent serums and moisturizers. The product is positioned as an accessible option in the calming toner category, offering multifunctional benefits through a blend of patented PDRN technology and soothing botanical ingredients without relying on overly complex formulations.
