COSRX - 5 PDRN B5 Vital Soothing Toner 280ml

COSRX 5 PDRN B5 Vital Soothing Toner is a lightweight watery toner built on five types of PDRN with vitamin B5 — 280ml of soothing hydration for skin that looks tired and dull.

Five types of PDRN, not one

Most PDRN products use a single source. This one draws from five: salmon, centella asiatica, rice, lactobacillus and sea grape. The plant and microbial sources matter — vegan PDRN is one of the notable K-beauty shifts of 2026, moving the ingredient beyond its salmon-DNA origins.

PDRN, the defining ingredient of 2026

PDRN went from clinic-only to consumer shelves faster than almost any recent ingredient, and it now anchors the regenerative skincare conversation. It sits alongside exosomes and spicules as the ingredients driving the category forward.

Vitamin B5 for comfort

Panthenol — one of the most dependable soothing and moisture-binding ingredients in skincare, and a staple in formulas for skin that reacts to environmental stress.

Eight types of hyaluronic acid

Hyaluronic acid comes in different molecular weights: larger molecules hold water at the surface, smaller ones spread through the upper layers. Eight covers considerably more ground than one.

Plus niacinamide, allantoin, peptides and adenosine

An unusually full ingredient list for a toner. Niacinamide for evenness, allantoin for soothing, peptides and adenosine for the look of firmness.

280ml means you can use it properly

Enough to sweep on generously twice daily, or to soak cotton pads for a five-minute hydrating pack. Rationing a toner is how it stops working.

Frequently asked questions

What is PDRN?

Polydeoxyribonucleotide — originally derived from salmon DNA, now also produced from plant and microbial sources. It’s used in Korean formulas aimed at skin recovery and hydration.

Is this vegan?

No — one of the five PDRN sources is salmon. The other four are plant or microbial.

Where does a toner go in my routine?

After cleansing, before serum. Apply to slightly damp skin so it spreads evenly.

Can I use it with other actives?

Yes — the formula is soothing rather than exfoliating, so it layers under most things. Introduce one new active at a time.

Is it suitable for sensitive skin?

The B5 and allantoin base is built with that in mind. Patch test first if your skin reacts easily.
