PDRN Intensive Ampoule

Kiara Reju

Kiara Reju's PDRN Intensive Ampoule is the flagship expression of a brand built entirely around polydeoxyribonucleotide technology. Unlike multi-category cosmetic lines that add PDRN as a marketing ingredient, Kiara Reju formulates every product around PDRN as the primary active — and the PDRN Intensive Ampoule concentrates that specialization into a 30mL clinic-channel treatment used inside Korean aesthetic clinics and dermatology offices. The formula delivers 2% salmon-derived PDRN with nucleic acid purity exceeding 95%, stabilized through Kiara Reju's proprietary preservation system to maintain bioactivity across the product's full shelf life. The molecular weight is deliberately optimized to a 50–1500 kDa window — large enough to retain the fragment-recognition properties that activate the A2A adenosine receptor, small enough to penetrate the stratum corneum and reach viable epidermal layers where fibroblast stimulation occurs. Supporting actives are chosen to complement PDRN's regenerative mechanism rather than compete with it: sodium hyaluronate for multi-depth hydration, beta-glucan for barrier reinforcement and soothing, niacinamide for tone evenness and barrier lipid support, panthenol and allantoin for calming, centella asiatica for redness control, and adenosine for firmness. The ampoule's silky, ultra-light slip forms an invisible second-skin layer that layers under any moisturizer or sunscreen without pilling — making it suitable for daily use, during and after aesthetic procedures, and on compromised or mature skin that needs rebuilding rather than resurfacing.
