Salmon DNA Skin Booster (PDRN): What Does the Latest Research Reveal?

PDRN and Polynucleotide: More Than Just 'Salmon DNA' – What Are They Medically?

Medically, PDRN (Polydeoxyribonucleotide) and PN (Polynucleotide) are highly purified DNA fragments extracted from the sperm of salmon (Oncorhynchus mykiss or Oncorhynchus keta). Salmon DNA is chosen due to its structural similarity to human DNA, ensuring good compatibility with the body and a low chance of allergic reactions once purified to remove other proteins.

Although derived from the same source, PDRN and PN differ in molecular size. Generally, PN has longer and more complex DNA strands than PDRN, providing a better scaffolding effect for skin cells to attach to and remaining in the skin longer. Conversely, PDRN, being smaller, primarily focuses on signaling to stimulate cell repair (Signaling effect). The choice of treatment therefore depends on the specific treatment goals and individual skin concerns, which will be assessed and advised upon by a medical professional.

In-depth Mechanism: How PDRN Rejuvenates Skin at a Cellular Level According to Research

The primary mechanism for PDRN's recognition in medical research is its ability to bind to cell surface receptors known as A2A Adenosine Receptors. Stimulating these receptors leads to several cellular changes simultaneously. Firstly, it reduces inflammation (Anti-inflammatory effect), a key cause of skin cell degradation. Secondly, it stimulates the secretion of growth factors, such as VEGF (Vascular Endothelial Growth Factor), which enhances blood circulation and improves nutrient delivery to the skin.

Beyond signaling, PDRN also acts as a 'precursor' for cells in a process called the Salvage Pathway. When skin cells are damaged, for instance, from sun exposure or pollution in Pattaya, they require raw materials to repair their own DNA. PDRN provides these fundamental components, allowing cells to create new DNA immediately without needing to synthesize them entirely from scratch. This process helps accelerate and enhance the efficiency of skin repair, stimulating Fibroblast cells to produce new collagen and elastin, resulting in stronger, more elastic, and healthier skin from its internal structure.

Who is Suitable for PDRN/Polynucleotide?

PDRN is suitable for individuals seeking to rejuvenate overall 'skin quality' rather than significant facial contour changes. The primary target group includes those with early signs of aging, such as fine lines, especially around the eyes and mouth where fillers might appear unnatural; individuals with dry, dehydrated, inelastic, uneven, large-pored, or dull and tired-looking skin, often resulting from regular sun exposure and pollution.

Furthermore, with its wound-healing and tissue-regenerating properties, PDRN is an interesting option for those looking to address certain types of scars, such as atrophic scars from acne, or even early-stage stretch marks. It helps stimulate the gradual formation of new tissue, making scars shallower and more consistent in color with the surrounding skin.

However, there are precautions for certain individuals, such as those with a severe allergy to fish or fish products, individuals with active skin infections in the treatment area, pregnant or breastfeeding women, and those with certain autoimmune diseases. It is crucial to consult a doctor thoroughly before deciding on treatment to ensure safety and favorable outcomes.

Comparing PDRN with Other Skin Boosters: Hyaluronic Acid (HA) and Collagen

When compared to Hyaluronic Acid (HA) skin boosters, such as Restylane® Vital Light, the mechanisms of action differ significantly. HA primarily functions by drawing water into the skin (Hydration), quickly making the skin moisturized and plump. Its results mainly focus on providing hydration. In contrast, PDRN acts as a Biostimulator, stimulating skin cells to repair and generate new skin components on their own. Therefore, PDRN's results represent a change in skin quality from within, which will gradually become visible and emphasize long-term skin health sustainability.

When compared to Collagen Biostimulators or Collagen Fillers, such as TheraFill® available at Mediqueen Clinic, their objectives are similar in stimulating collagen production, but with different specifics. TheraFill® provides pure collagen as a structure for cells to attach to and simultaneously stimulates new collagen formation. PDRN, however, operates at a broader level, not only stimulating collagen but also reducing inflammation, increasing blood circulation, and repairing cell DNA, thus offering comprehensive overall skin health care. The choice of treatment therefore depends on the primary skin concern, which will be diagnosed and a suitable treatment plan devised by a medical professional.

Treatment Steps and Expectations: The Process at Mediqueen Clinic

The process begins with a medical consultation (supervised by physician registration no. W.37670) for a detailed skin assessment and to develop a personalized treatment plan suitable for you. Before the treatment, a topical anesthetic will be applied to the injection area for approximately 30-45 minutes to minimize discomfort. Subsequently, the physician will use an intradermal injection technique to administer the substance in small dots, dispersed across the desired rejuvenation areas, such as the entire face, neck, or back of the hands. This procedure typically does not take long.

It is important to understand that PDRN is not a single-session treatment with immediate results. Generally, it is recommended to undergo a continuous course of approximately 3-4 sessions, spaced 2-4 weeks apart, to ensure sustained stimulation of skin cells and achieve noticeable results. After completing the course, follow-up treatments may be performed every 6-12 months to maintain the improved skin condition. Results will gradually become apparent; you may start to notice smoother, more hydrated, and brighter-looking skin 2-4 weeks after treatment, and improvements will continue throughout the treatment course. Ultimately, the final results depend on individual skin condition and self-care.

Post-Treatment Care and Potential Side Effects

After treatment, the injected area may experience redness, small bumps (papules), or bruising from the needle. These are normal symptoms and usually subside within 1-3 days. During the first 24 hours, avoid touching, massaging, or vigorously rubbing the injected area. Refrain from applying makeup and avoid activities that significantly increase blood circulation, such as strenuous exercise, sauna use, or alcohol consumption, to reduce the risk of increased swelling or bruising.

Long-term self-care after treatment, especially in Pattaya's hot and humid climate, involves consistent application of sunscreen and avoiding strong sunlight to protect the skin undergoing rejuvenation. Severe side effects are very rare, particularly when performed by specialized medical professionals in a standardized medical facility using products certified by the Thai FDA. Therefore, choosing the right clinic and physician is extremely crucial for safety.
