1. Product Overview

PDRN (Polydeoxyribonucleotide) is a natural biomacromolecule extracted from high-quality salmon milt. It is a polymer composed of deoxyribonucleotide monomers linked by phosphodiester bonds. As a functional cosmetic raw material, it has excellent biocompatibility and skin-friendly properties. It can effectively promote skin cell proliferation and repair, regulate skin microcirculation, and exert anti-inflammatory, moisturizing and anti-aging effects. It is widely used in high-end skincare products such as repair serums, anti-wrinkle creams, and post-sun repair products.

4. Core Applications

1. Anti-aging Skincare Products: Promote the synthesis of collagen and elastin in skin fibroblasts, improve skin elasticity, reduce fine lines and wrinkles, and delay skin aging.
2. Skin Repair Products: Accelerate the repair of damaged skin barriers, suitable for post-acne repair, post-sun repair, and repair of sensitive and fragile skin.
3. Anti-inflammatory & Soothing Products: Inhibit the release of inflammatory factors, relieve skin redness, swelling and irritation, and improve sensitive skin symptoms.
4. Moisturizing & Brightening Products: Regulate skin water-oil balance, enhance skin moisture retention capacity, and improve dull skin tone to make skin bright and translucent.
5. Post-medical Beauty Repair Products: Used in products after laser, microneedle and other medical beauty projects to shorten the skin recovery period and reduce side effects such as redness and swelling.
