A first-step toner with five PDRN sources listed by the brand

COSRX directs users to apply this toner as the first step after cleansing and massage until absorbed. The page describes its “5 PDRN” concept as salmon, Centella asiatica, rice, Lactobacillus and sea grapes, while the disclosed ingredient list names Sodium DNA and Hydrolyzed DNA along with Centella extract and Lactobacillus ferment. It does not give a concentration for the PDRN complex.

The formula also lists panthenol, niacinamide, alpha-arbutin, adenosine and eight hyaluronic-acid forms. The brand’s claims about renewal and barrier repair are product-page claims; this page does not provide study conditions for those outcomes.

Products with overlapping ingredient lists

Calculations use complete ingredient lists for the stated market and product version. Listed names do not establish concentrations, equivalent effects or allergy suitability.

Explore products in the same use group with overlapping ingredient lists, then compare their texture, directions and ingredient differences.

How are candidates selected?

Candidates share the page’s language, market context and use group and have a complete ingredient list available. Names are normalized for spacing and reviewed synonyms; duplicate names count once.

The default order divides shared names by all distinct names across both lists: 10 shared names out of 20 distinct names gives 10 ÷ 20. You can instead order by the number of shared names. Up to five candidates are shown.

Ingredient overlap does not establish equivalent effects or a cheaper substitute. Concentrations, ingredient order, finished-product tests and feel are not part of this calculation. Missing lists are not treated as missing ingredients.
