PRP vs Exosomes vs Polynucleotides: Which Regenerative Treatment Is Right for You?

The Rise of Regenerative Aesthetics

The biggest shift in aesthetic medicine over the past two years has been the move from "filling and freezing" towards genuine skin regeneration. Three treatments lead this revolution: PRP (Platelet-Rich Plasma), Exosomes, and Polynucleotides. All three aim to improve skin quality from within, but they work through very different mechanisms. Understanding these differences is key to choosing the right one.

PRP (Platelet-Rich Plasma): Your Own Blood, Your Own Healing

PRP therapy involves drawing a small amount of your blood, spinning it in a centrifuge to isolate the platelet-rich portion, and re-injecting it into target areas. Platelets contain growth factors that stimulate collagen production, tissue repair, and cell renewal.

Best For:

• Under-eye rejuvenation and dark circles
• Hair restoration and thinning hair
• Overall skin quality improvement
• Enhancing results when combined with microneedling

Key Considerations:

Because PRP uses your own blood, there is virtually zero risk of allergic reaction. Results are gradual, typically visible after 3–4 weeks, and a course of 3 sessions is recommended. The quality of PRP depends on your own platelet count and overall health, so results can vary between individuals.

Exosomes: The Next Generation of Cell Communication

Exosomes are tiny vesicles (nano-sized packets) that cells use to communicate with each other. In aesthetic medicine, exosome therapy delivers concentrated growth factors, proteins, and signalling molecules directly to your skin cells, instructing them to repair and regenerate.

Best For:

• Accelerating healing after laser or microneedling treatments
• Improving skin texture, tone, and radiance
• Advanced hair restoration protocols
• Patients who want enhanced results without additional downtime

Key Considerations:

Exosomes are derived from lab-cultured stem cells, not from your own body. This means consistent potency regardless of your age or health status. They are often used as a "booster" alongside other treatments rather than as a standalone procedure. At INNODERM, we frequently pair exosomes with microneedling for amplified results.

Polynucleotides: Deep Cellular Regeneration

Polynucleotides (PDRN) are DNA fragments derived from salmon that stimulate your fibroblasts — the cells that produce collagen, elastin, and natural hyaluronic acid. They work at a deeper biological level than either PRP or exosomes, essentially "switching on" your skin's repair mechanisms.

Best For:

• Significant improvement in skin elasticity and firmness
• Treating crepey, thin, or dehydrated skin
• Under-eye hollowing and dark circles
• Long-term anti-ageing and skin quality

Key Considerations:

Polynucleotides deliver the most pronounced structural improvements of the three treatments. Results build gradually over 2–3 months and are long-lasting. A typical course is 3 sessions spaced 3–4 weeks apart. They can be combined with both PRP and exosome treatments for comprehensive regeneration.

Head-to-Head Comparison

PRP is ideal if you prefer a fully autologous (your own body) approach and want versatile treatment for both skin and hair. Exosomes excel as a treatment amplifier and recovery accelerator, particularly powerful after energy-based treatments. Polynucleotides deliver the deepest regenerative impact on skin structure and are the best standalone option for reversing skin quality decline.

Can I Combine Them?

Absolutely. In fact, combining regenerative treatments is one of the most exciting developments in modern aesthetics. A popular protocol at INNODERM involves polynucleotides for deep regeneration, paired with PRP microneedling for surface-level collagen stimulation, and exosomes to accelerate healing between sessions. Your practitioner will design a protocol based on your specific skin concerns and budget.

Which Should You Choose?

The honest answer is that it depends on your goals, skin condition, and budget. During your consultation at INNODERM, we assess your skin under clinical lighting, discuss your concerns, and recommend the regenerative approach — single or combined — that will deliver the results you are looking for. Book your skin assessment to find out which path is right for you.
