PDRN (Polydeoxyribonucleotide) is a highly purified DNA-derived compound consisting of small DNA fragments. In aesthetic medicine and skin rejuvenation, PDRN is commonly extracted from salmon or trout DNA due to its high biocompatibility with human tissue.

PDRN has been widely studied for its role in supporting the skin's natural repair process. It helps promote tissue regeneration, modulate inflammation, stimulate collagen production, and support the recovery of damaged skin cells. As a result, the skin may appear healthier, better hydrated, smoother, and more elastic.

Because of these properties, PDRN is commonly incorporated into skin rejuvenation treatments such as the P-Cell Program. It is also frequently used to support skin recovery following laser procedures and other aesthetic treatments, as recommended by a physician.

Key Benefits of the P-Cell Program

The P-Cell Program combines Polydeoxyribonucleotide (PDRN) and Hyaluronic Acid (HA) to provide comprehensive skin rejuvenation.

PDRN supports the skin's natural repair mechanisms and collagen production, while HA replenishes moisture and helps maintain optimal skin hydration. Together, these ingredients work synergistically to improve skin texture, hydration, elasticity, and overall skin quality.

Key advantages of the P-Cell Program include:

• Supports skin regeneration from within through PDRN, promoting the skin's natural repair process and helping restore weakened skin cells.
• Provides deep hydration with Hyaluronic Acid (HA), helping the skin appear plumper while reducing dryness and dehydration.
• Improves overall skin quality, promoting smoother skin texture, a more even complexion, and enhanced elasticity.
• Suitable for skin affected by environmental stressors, including sun exposure, pollution, and early visible signs of aging.
• Addresses multiple skin concerns in a single treatment, including dullness, fine lines, enlarged pores, and uneven skin texture.

The P-Cell Program is designed to improve overall skin quality and hydration while supporting the skin's natural regenerative processes. Depending on individual skin conditions, the treatment may help:



• Improve skin hydration and reduce dryness or dehydration.
• Enhance skin radiance, giving the complexion a healthier, plumper, and more luminous appearance.
• Refine skin texture and reduce the appearance of enlarged pores.
• Improve the appearance of fine lines and support skin firmness.
• Improve the appearance of mild post-acne marks and shallow acne scars, depending on individual skin conditions.
• Revitalize skin affected by environmental damage, including sun exposure and pollution.
• Support the skin barrier (skin barrier function), helping maintain healthier and more resilient skin.

The P-Cell Program can be administered to various areas requiring skin rejuvenation and improved skin quality. Common treatment areas include:



• Face
• Under-Eye Area
• Forehead
• Cheeks and Areas with Acne Marks
• Neck and Other Areas Requiring Skin Rejuvenation

The P-Cell Program may be suitable for individuals who:



• Have dry or dehydrated skin with a dull or tired appearance.
• Wish to achieve plumper, more hydrated, and healthier-looking skin.
• Have fine lines or early signs of reduced skin elasticity.
• Have enlarged pores or uneven skin texture.
• Have mild to moderate post-acne marks or shallow acne scars and would like to improve overall skin quality.
• Wish to restore skin affected by sun exposure, environmental pollution, or everyday environmental stressors.

The P-Cell Program may not be appropriate for everyone. A consultation with a physician is recommended before treatment, particularly for individuals with the following conditions:



• Active skin infections, open wounds, or inflammation at the intended treatment site.
• A known allergy to any ingredient in the product.
• A history of seafood allergy, as certain PDRN products are derived from salmon or trout DNA.
• Pregnant or breastfeeding individuals, unless advised otherwise by their physician.
• Certain underlying medical conditions or bleeding disorders.
• Individuals taking anticoagulants (blood thinners) or medications that affect blood clotting should inform their physician before treatment.
• Individuals with severe skin conditions or unrealistic expectations of immediate results should undergo a thorough medical evaluation to determine the most appropriate treatment approach.

Proper preparation before treatment can help support a smooth procedure and optimize your skin's recovery. Before undergoing the P-Cell Program, your physician may recommend the following:



• Inform your physician about your medical history, underlying health conditions, current medications, dietary supplements, and any allergies.
• Avoid alcohol for approximately 24 hours before treatment.
• Temporarily discontinue certain medications or supplements that may affect blood clotting, if advised by your physician.
• Get adequate rest before your appointment to support your body's natural healing process.
• Avoid skin treatments that may cause irritation, such as facial scrubs, chemical exfoliants, or high-strength exfoliating products, for several days before treatment.
• Arrive with clean skin and avoid wearing makeup on the day of your appointment whenever possible.

Following your physician's aftercare instructions is important to support the skin's recovery and achieve optimal treatment outcomes.

After the procedure, it is generally recommended to:



• Avoid touching, pressing, or massaging the treated area during the initial healing period.
• Avoid wearing makeup for at least 12–24 hours, or as directed by your physician.
• Avoid excessive heat exposure, including saunas, steam rooms, hot baths, and strenuous exercise, for 24–48 hours after treatment.
• Protect your skin from direct sun exposure and apply a broad-spectrum sunscreen daily.
• Avoid potentially irritating skincare products, including facial scrubs and exfoliating acids, during the early recovery period.
• Stay well hydrated by drinking plenty of water to help maintain skin hydration.
• Follow all post-treatment instructions provided by your physician and attend scheduled follow-up appointments.
