What is the Difference Between PRP, Exosome, and Rejuran? A Physician's Comparison
Choosing between PRP, Exosome, and Rejuran depends primarily on your individual skin concerns and goals. PRP utilizes your own blood platelets to stimulate general repair, Rejuran uses salmon DNA extracts (Polynucleotides) to repair skin cells and reconstruct skin structure, while Exosomes utilize stem cell messengers for holistic skin rejuvenation and inflammation reduction. Consulting with a physician for a skin assessment is an important step in selecting the treatment well suited for each individual.
Key points
- PRP (Platelet-Rich Plasma) is derived from the recipient's own blood and contains Growth Factors that help stimulate overall skin repair, well suited for those seeking holistic skin rejuvenation.
- Rejuran (Polynucleotide) is extracted from salmon DNA and works to repair damaged skin cells while creating a supportive matrix for stronger skin, appropriate for acne scars, fine lines, and thin skin.
- Exosomes are cellular messengers derived from stem cells that are ultra-small and deep-penetrating, sending signals for cells to self-repair and reducing inflammation, suitable for sensitive skin or urgent rejuvenation.
- Treatment selection depends on a physician's diagnosis based on skin concerns, individual needs, and physical condition. In some cases, treatments may be combined for comprehensive results.
- All procedures should be performed by an experienced physician for safety and treatment effectiveness. Individual results vary.
The Science of Cellular Skin Rejuvenation: Understanding PRP, Exosome, and Rejuran
Modern aesthetic medicine has advanced beyond surface-level fixes to focus on restoring and repairing skin structure at the cellular level (Regenerative Medicine). PRP, Exosome, and Rejuran are three cornerstone treatments in this approach, each possessing distinct origins, mechanisms of action, and targeted skin benefits.
Understanding the differences among these three treatments is essential for selecting a procedure tailored to your specific skin needs—whether through natural physiological repair, targeted structural repair, or broad cell-signaling stimulation. At Mediqueen Clinic Pattaya, the medical team led by Dr. Pattaradet Charoenchang (Lic. 37670) emphasizes providing accurate information so patients can participate in selecting a suitable treatment plan.
PRP (Platelet-Rich Plasma): Harnessing the Repair Power of Autologous Platelets
PRP, or Platelet-Rich Plasma, involves processing a patient's own blood sample through centrifugation to isolate plasma containing platelet concentrations significantly higher than normal blood. The core mechanism of PRP lies in the abundant Growth Factors released by activated platelets, which act as signals instructing nearby stem cells to initiate tissue repair and regeneration.
The primary mechanism of PRP involves stimulating collagen and elastin synthesis and encouraging microvascular formation to improve nutrient delivery to the skin. This makes it appropriate for individuals looking to refresh overall skin tone, reduce fine lines, or address hair thinning. However, Growth Factor concentration in PRP varies among individuals based on age and health, which is an important consideration.
Rejuran: DNA Repair and Skin Barrier Rebuilding with Polynucleotide (PN)
Rejuran is a treatment centered on Polynucleotide (PN), highly purified DNA fragments extracted from natural salmon sperm with high biocompatibility with human DNA. This biocompatibility supports safety and minimizes immune reactivity. Unlike dermal fillers that provide volumetric filling, Rejuran functions by repairing skin cells damaged by factors such as solar radiation, pollution, or aging.
When injected into the dermis, PN molecules bind to receptors on fibroblast cells, stimulating the synthesis of new collagen and extracellular matrix components. Additionally, it provides a scaffolding effect for skin cell attachment and organized growth, enhancing skin density, firmness, and elasticity. It is well suited for individuals with thin skin, weakened skin barriers, enlarged pores, fine lines, or shallow acne scars, particularly in Pattaya's warm and humid climate.
Exosome: Advanced Cellular Communication Messengers for Comprehensive Skin Rejuvenation
Exosome technology represents a further advancement in skin rejuvenation. Exosomes are non-cellular nano-sized extracellular vesicles secreted by stem cells for intercellular communication. Packed with over 1,000 biomolecules—including Growth Factors, Cytokines, mRNA, and miRNA—they deliver instructions directing recipient cells to self-repair, lower inflammation, or generate new cellular structures.
A key feature of Exosomes is being cell-free therapy, containing no live cells, which reduces risks associated with live cell administration. Their small size allows efficient cell penetration. ASCE+ EXOSOME SRLV used at Mediqueen Clinic is derived from Damask Rose stem cells, offering anti-inflammatory properties and comprehensive skin recovery. It is well suited for sensitive skin, inflamed skin, post-laser recovery, or deep skin rejuvenation.
Direct Comparison: How to Choose the Appropriate Treatment for Your Skin Concerns
A direct comparison highlights clear distinctions: **PRP** relies on autologous physiological mechanisms for holistic skin support, though outcomes vary based on individual health. **Rejuran** focuses specifically on structural repair and strengthening, making it suitable for structural concerns like fine lines, laxity, and shallow scarring.
Meanwhile, **Exosome** focuses on cellular communication and signaling for optimal cellular performance, delivering benefits in anti-inflammation, collagen stimulation, and restoring weakened skin. Selecting a treatment depends on primary goals: PRP is a compelling option for general skin health improvement, Rejuran is suitable for thin skin and acne scars, and Exosome offers comprehensive recovery for delicate skin.
Personalized Treatment Planning: Why Medical Consultation Matters
No single treatment is universally suitable for everyone. Selecting the appropriate procedure requires a thorough skin evaluation by an experienced physician. Physicians assess multiple factors—including skin concerns, skin characteristics, age, lifestyle, and medical history—to design a safe and effective plan for each patient.
In certain cases, physicians may suggest combination therapy for enhanced outcomes, such as pairing Rejuran for structural support with Exosomes for anti-inflammation and accelerated cellular recovery. At Mediqueen Clinic Pattaya, we focus on personalized treatment planning prioritizing patient safety. Please note that individual treatment results vary.
FAQ
Are Rejuran or Exosome injections painful, and how long is the recovery period?
Topical anesthetic is applied before treatment to minimize discomfort. During the procedure, minor prickling sensations may be felt. Mild redness or small bumps may appear post-treatment, which typically resolve within 1–3 days. Patients can resume daily activities and wear makeup the following day, while avoiding heavy pressure, direct sun exposure, and alcohol consumption for the first 2–3 days.
Can Rejuran and Exosomes be performed in the same session?
Yes, they can be combined, and in many instances, dual application provides complementary benefits. A physician will design a suitable plan—such as using Rejuran to fortify skin structure and Exosomes to soothe inflammation and stimulate cellular recovery. Combined procedures should only be performed under expert medical supervision.
How frequently should treatments be done, and how long do results last?
Treatment frequency depends on individual skin condition and specific goals. Initially, physicians often recommend 2–3 sessions spaced 3–4 weeks apart to stimulate skin response, followed by maintenance every 6–12 months. Results last for an extended period, though skin continues to change over time with age. Regular care helps prolong benefits.
How do Exosomes differ from live stem cell injections?
Exosomes are cell-free extracts containing biomolecules derived from standardized laboratory-cultured stem cells, whereas live stem cell therapy involves injecting living cells into the body, carrying higher risks and stricter regulatory controls in many regions. Exosomes present a safer profile for utilizing stem cell regenerative signals.
