Regenerative treatments offer an option for patients who want to improve their skin by supporting the body’s repair mechanisms. While there are many regenerative options available, one option that you may not have heard of yet is PDRN.
PDRN is used to promote collagen production and assist with skin healing, particularly in cases involving irritation or damaged tissue. At AURAE MD, we serve La Jolla, San Diego and the surrounding areas, where we incorporate regenerative treatments like PDRN to help address underlying skin changes through biologically driven repair.
What Is PDRN?
PDRN, or polydeoxyribonucleotide, is a compound derived from purified DNA fragments that are usually sourced from salmon and then processed for medical use. It can be used in medical settings for wound care and tissue repair because of its regenerative properties. In regenerative medicine, it can be used either as an injectable or a topical, though at AURAE MD, we typically administer it through microinfusion or after other treatments like microneedling.
How PDRN Supports Fibroblast Activity to Stimulate Collagen
What Are Fibroblasts?
Fibroblasts are cells that are found in abundance in the connective tissue of the body. They have flexible roles and can adapt as necessary during growth and healing. These cells produce the extracellular matrix, which is the supportive material that surrounds and holds cells together and contains proteins like collagen to give the tissue strength. When an injury occurs, fibroblasts multiply and move into the affected area, where they produce extra collagen to stabilize and repair the damaged tissue.
PDRN and Cellular Signaling
When applied to the skin, PDRN serum interacts with A2A adenosine receptors, which are protein structures on the surface of cells that receive and transmit signals. This pathway is part of the body’s communication system that helps regulate inflammation and tissue repair. When PDRN activates these receptors, it can encourage fibroblasts to increase collagen production and participate actively in rebuilding damaged tissue.
Visible Benefits of Fibroblast Activation
As fibroblasts produce more collagen, the skin’s internal support network becomes stronger. This has implications for the appearance and texture of the skin, which looks smoother and feels firmer as it strengthens. Supporting the skin from within can also help with fine lines and wrinkles that form from a loss of collagen.
PDRN and Tissue Regeneration
DNA Fragments and Cellular Repair
PDRN is made of DNA fragments that can be used during tissue repair. When introduced to the skin, PDRN activates specific receptors on cells that trigger repair and replication. The DNA fragments can also be recycled by the body into building blocks that support new cell growth. This process is helpful in areas affected by stress or injury, where cells must divide and replace damaged tissue.
Angiogenesis and Improved Blood Supply
PDRN may also help with the formation of new blood vessels within the tissue. Blood vessels carry oxygen and nutrients that the skin needs to maintain normal function and carry out repair. Better circulation also helps clear out metabolic waste that can accumulate in inflamed areas and provide a more stable environment for tissue recovery.
Long-Term Skin Strengthening
The skin can thin with age as collagen decreases and becomes more sensitive and less resilient. With PDRN skincare and treatments, the dermis can be more supported, helping it to respond better to environmental stress and inflammation.
Anti-Inflammatory Effects of PDRN
Reducing Inflammatory Markers
When your body experiences injury, irritation or infection, it releases chemical signals called inflammatory markers. These include cytokines, the proteins that help regulate immune activity and increase redness and swelling when present in high amounts. PDRN is thought to influence pathways that lower the production of certain pro-inflammatory cytokines to calm overactive immune responses in the skin.
Benefits for Sensitive and Compromised Skin
Sensitive or compromised skin often has a weakened barrier, meaning the outer protective layer does not effectively retain moisture or block irritants. This can lead to ongoing inflammation, dryness and delayed healing. Regulating inflammatory signals and supporting tissue repair reduces visible redness and improves overall skin tolerance in those with irritated or sensitive skin.
Why Controlling Inflammation Matters for Aging
Chronic low-grade inflammation contributes to the gradual breakdown of collagen and elastin. When inflammatory mediators stay elevated, they can accelerate tissue degradation and slow normal repair cycles. Managing inflammation helps protect the dermal structure and maintain more consistent collagen production.
The Wound-Healing Properties of PDRN
Accelerating the Healing Process
Wound healing occurs in stages that include inflammation, tissue formation and remodeling. During the inflammatory phase, immune cells move into the area to remove bacteria and damaged tissue. Next, collagen and new blood vessels are produced in the tissue formation phase. During the remodeling phase, collagen fibers are reorganized and strengthened to help make the skin smoother and more stable. PDRN serum supports these phases by encouraging cell replication and improving local blood supply to help shorten recovery time and promote more efficient repair.
Clinical Applications
PDRN has been used to help chronic wounds, ulcers and surgical sites heal. It has also been incorporated into aesthetic treatments to help with post-treatment recovery after laser resurfacing or microneedling.
Improved Scar Quality
PDRN serum can also be used to help injured areas to heal with a less visible scar. Scar formation is influenced by how collagen is rebuilt during the remodeling phase of healing, when the body replaces early repair tissue with stronger collagen fibers and reorganizes them. As inflammation is regulated and there is more organized collagen turnover, scar tissue can heal more evenly.
