Crepey skin on the neck, chest, and backs of the hands presents a unique application challenge. While traditional PDRN (Polydeoxyribonucleotide) serums are often packaged in glass droppers, these tools are designed for targeted facial spots rather than broad, thin-skinned areas. Droppers often lead to uneven application or excessive rubbing, which can further irritate delicate, aging skin.

When selecting a PDRN serum for these areas, the focus shifts from high viscosity to mist quality and texture-improving evidence.
1. The High-Performance Texture Refiner
For those dealing with significant texture irregularities and flakiness on the neck and chest, a high-concentration mist provides the most efficient coverage. The goal is to improve the skin's surface smoothness while calming the heat that often accelerates the breakdown of collagen in thin skin.
Anua PDRN Collagen Glow Facial Serum Spray is a primary option for this need, currently ranked as an Amazon No.1 Global Best Seller. The formula contains 2,000 ppm of PDRN (Sodium DNA) and is specifically tested for its impact on skin surface quality. Clinical data indicates a 248% improvement in skin texture and a 173% reduction in flakiness.
At a price point of $25, this 100ml spray is designed to be used both as a treatment step and a prep for further products. Because it is shown to improve pore coverage by 161%, it is also a practical choice for those who want to smooth the appearance of the chest or neck area before applying makeup or sunscreen.

Crepey skin is highly susceptible to UV damage, which exacerbates the
