PDRN: Tradition meets modern actives.

PDRN has become one of the most intriguing ingredients in skincare, buzzed for its regenerative power. While its nickname ‘salmon sperm DNA’ often steals attention, the real story is even more captivating. It originated through human placenta extracts for skin renewal, the science evolved toward salmon sperm, chosen for its exceptional biocompatibility and similar DNA structure, an alternative that delivers the same results.

In Korea, it gained popularity as the so-called ‘healer shot’ - an in-clinic injection designed to restore plumpness, repair damage, and boost elasticity. Effective, yes, but also invasive and (very) painful. Over time, the concept evolved into gentler, at-home skincare formats, making its way into the products you now see in the beauty market.

That said, PDRN is still animal-derived. With the rising demand for clean and ethical formulations, forward-looking brands have started developing plant-based alternatives to deliver similar regenerative benefits but vegan and cruelty-free.

Thus, KNOURS brings the PDRN Rice & Green Tea line: your ultimate at-home skin barrier treatment. Inspired by PDRN’s powerful effects, KNOURS set out to find the ideal plant-derived duo - Rice and Green Tea, a pairing that targets dullness, sensitivity, and barrier weakness. Specifically, Rice PDRN is formulated to strengthen the skin barrier and smoothen texture, while Green tea PDRN soothes skin and controls sebum production - helping tighten pores.

The collection includes a toner, serum, and peel-off mask:
