Birch Juice PDRN Moisture Serum

Round Lab

Round Lab built its reputation on the Birch Juice Moisturizing line, and this PDRN extension brings regenerative science into that hydration-first philosophy. The formula pairs salmon-derived polydeoxyribonucleotide with Finnish birch juice — a natural source of minerals, amino acids, and antioxidants that has been used in Nordic skincare for centuries. The texture is a lightweight, slightly viscous serum that absorbs cleanly without residue. Birch juice provides immediate surface hydration while PDRN works at the cellular level to stimulate fibroblast activity and support collagen synthesis. Panthenol and beta-glucan round out the formula with soothing and barrier-reinforcing benefits. This is a strong choice for anyone who already loves Round Lab's approach — effective, affordable Korean skincare with a clean ingredient philosophy — and wants to add PDRN to their routine without switching brands.
