Polydeoxyribonucleotide (PDRN) consists of DNA fragments with molecular weights ranging from 50 to 1 500 kDa, which are mainly extracted from the sperm cells of salmon trout or chum salmon. Many preclinical and clinical studies have demonstrated the properties of PDRN. These include anti-inflammatory, anti-apoptotic, anti-osteoporotic, anti-melanogenetic, anti-allodynic, anti-osteonecrotic, bone regenerative, tissue damage preventive, anti-ulcerative, and wound healing properties, which are mediated by the activation of the adenosine A2A receptor and salvage pathways. Moreover, PDRN promotes angiogenesis, cellular activity, collagen synthesis, soft tissue regeneration, and skin priming and revitalization and can be used to treat hyperpigmentation. Therefore, this review assessed the potential use of PDRN as an anti-aging agent for the skin.
