PDRN CarePDRN Injection: Complete Guide to Treatment, Benefits & Results
PDRN injection is the most direct and clinically validated method of delivering polydeoxyribonucleotide into the skin for therapeutic and aesthetic purposes. Originally developed in Italy and perfected in Korean aesthetic medicine, PDRN injections involve administering purified polynucleotide fragments derived from salmon DNA directly into the dermis, where they activate the adenosine A2A receptor pathway to trigger tissue regeneration. This is the gold standard delivery method used in most clinical studies demonstrating PDRN's efficacy. The injectable form of PDRN allows precise targeting of specific skin concerns. For facial rejuvenation, micro-deposits are placed across the treatment area to create a uniform regenerative effect. For targeted concerns like acne scars or under-eye hollows, PDRN can be concentrated in specific zones where tissue repair is most needed. The injectable route ensures that a therapeutic concentration of PDRN reaches the dermal fibroblasts, which is difficult to achieve with topical application alone due to the barrier function of the stratum corneum. PDRN injections have a robust evidence base supporting their efficacy. Clinical trials have demonstrated measurable increases in dermal thickness, collagen density, skin elasticity, and hydration following treatment courses. The mechanism is well understood: PDRN fragments bind to adenosine A2A receptors, triggering intracellular signaling cascades that upregulate collagen synthesis, promote angiogenesis, suppress inflammatory mediators, and activate the nucleotide salvage pathway for DNA repair. The treatment has an excellent safety profile with decades of clinical use in wound healing and tissue repair before its adoption in aesthetic medicine. Side effects are typically limited to mild injection-site reactions including temporary redness, swelling, and occasional bruising. Serious adverse events are exceedingly rare. PDRN injections are performed by dermatologists, plastic surgeons, and trained aesthetic practitioners in clinical settings.
How It Works
PDRN injection begins with a thorough consultation to assess the patient's skin condition, discuss goals, and identify any contraindications (including known allergy to fish or salmon products). The treatment area is cleansed and photographed for documentation. A topical anesthetic cream is applied to the treatment area and left for 20-30 minutes to ensure comfort. After removing the numbing cream and re-cleansing with antiseptic, the practitioner prepares the PDRN product according to manufacturer guidelines. Most PDRN injectables come in pre-filled syringes containing 2-3ml of product. The injection technique varies by product and treatment goal. The most common approach is serial micro-injections using a 30-32 gauge needle, placing small boluses (0.02-0.05ml) of PDRN at regular intervals of 1-2cm apart across the treatment area. The injection depth is typically 1-2mm into the superficial to mid-dermis. Some practitioners prefer a linear retrograde technique or use a cannula for certain areas. For products like Rejuran, a nappage technique (multiple superficial injections) is the standard approach. The face is typically divided into treatment zones — forehead, periorbital, cheeks, nasolabial area, chin, and jawline — with the injection density and depth adjusted for each zone's specific skin characteristics. After all injections are completed, gentle pressure is applied to minimize bruising, and a soothing serum or cream is applied. The procedure takes 20-40 minutes. Patients are advised to avoid touching the face, applying makeup, or engaging in strenuous exercise for 24 hours post-treatment.
