Crepey skin—characterized by a thin, papery texture and a loss of elasticity—requires more than just surface-level moisture. While traditional moisturizers address dryness, they often fail to treat the underlying thinning of the dermal layer. This is why Polydeoxyribonucleotide (PDRN), a DNA-derived ingredient typically sourced from salmon, has become a focal point in Korean skincare for those seeking to restore skin density and smoothness.
When choosing a PDRN serum for crepey textures, the decision usually comes down to three factors: the concentration of active DNA fragments, the presence of supporting hydrators like hyaluronic acid, and the delivery method. For skin that feels fragile or "deflated," the goal is to find a formula that plumps the appearance of fine lines while actively smoothing the skin's surface.
Criteria for Selecting a PDRN Serum
Not all PDRN products are formulated for the same result. To address crepey skin effectively, consider these three criteria:
- Texture Smoothing: Look for clinical evidence regarding texture improvement. Crepey skin is inherently uneven; a serum should demonstrate a measurable ability to reduce flakiness and refine the skin's surface.
- Synergetic Ingredients: PDRN works best for volume loss when paired with collagen and hyaluronic acid. These ingredients provide the immediate
