The Rise of Polynucleotides in Aesthetic Medicine: Why Korean Clinics Are Embracing DNA-Based Skin Regeneration
Discover why polynucleotide treatments such as Rejuran are attracting attention in aesthetic medicine. Learn how Korean clinics are exploring regenerative approaches focused on skin quality, repair, collagen maintenance and long-term skin health.
A New Chapter in Aesthetic Medicine
Walk into a leading dermatology clinic in Seoul today and you may notice a shift in the conversation. Discussions are no longer centred solely on wrinkles, volume loss or visible signs of skin ageing. Instead, practitioners are increasingly discussing regeneration, skin quality, collagen maintenance and cellular repair.
This reflects one of the most significant developments in modern aesthetic medicine: the growing interest in regenerative therapies. At the centre of this movement are polynucleotides, a category of treatments that has attracted attention from both practitioners and patients.
Unlike procedures designed to create immediate structural change, polynucleotides are used with the aim of supporting the skin’s natural repair processes. Their growing popularity reflects a broader interest in treatments that focus on skin function and overall skin quality rather than dramatic cosmetic change.
What Are Polynucleotides?
Polynucleotides are purified DNA fragments that have been investigated for their potential role in tissue repair and regeneration. Many aesthetic formulations are derived from highly purified salmon DNA due to its biocompatibility with human tissue.
These compounds have been studied in various medical settings for their possible involvement in wound healing, tissue repair and inflammation-related processes. In aesthetic medicine, polynucleotide-based treatments are increasingly being explored for their potential to support skin quality, hydration, elasticity and overall skin resilience.
Rather than adding volume, polynucleotides are intended to work within the skin environment itself, with the aim of supporting normal biological processes over time.
Why South Korea Became a Global Leader
South Korea has developed a reputation as one of the world’s most innovative aesthetic markets. Many trends that later gain international popularity first emerge within Korean clinics.
One reason polynucleotides have attracted interest in Korea is that they align closely with the country’s beauty philosophy. Korean patients often place significant value on healthy-looking, clear and radiant skin rather than dramatic cosmetic transformation.
The emphasis is not simply on looking younger but on maintaining skin quality for as long as possible. Polynucleotide-based treatments fit naturally within this approach because they focus on maintenance, repair and prevention.
The Rejuran Effect
No discussion of polynucleotides would be complete without mentioning Rejuran. Often credited with increasing public awareness of regenerative aesthetics, Rejuran has become one of the most widely recognised polynucleotide-based treatments internationally.
Patients may enquire about Rejuran for concerns such as skin texture, visible pores, acne scarring, fine lines and overall skin quality. Much of its appeal lies in the perception that it focuses on supporting skin quality rather than producing an immediate or obvious cosmetic change.
The visibility of Rejuran within the aesthetic industry has contributed to increased awareness of DNA-based regenerative therapies globally.
How Polynucleotides May Support Skin Health
As skin ages, collagen production naturally declines, healing processes may become less efficient and various biological changes can affect overall skin quality.
Polynucleotides are being investigated for their potential role in supporting tissue repair and maintaining a healthy skin environment. Reported outcomes may include:
Improved skin hydration
Enhanced skin elasticity
Improvements in skin texture
Support for skin repair processes
Support for skin barrier function
Improvements in the appearance of acne scarring
Any observable changes may develop gradually over time, and individual responses can vary considerably.
The Shift Towards Regenerative Aesthetics
For many years, aesthetic medicine focused primarily on correction. Today, increasing attention is being given to treatments that aim to support skin quality before more significant age-related changes occur.
This trend has contributed to growing interest in regenerative therapies such as:
Polynucleotides
Exosomes
Platelet-rich fibrin therapies
Biostimulators
Growth factor-based treatments
Together, these technologies represent an evolving area of aesthetic medicine focused on supporting the body’s natural repair mechanisms.
Polynucleotides Versus Traditional Approaches
Traditional aesthetic treatments often target a specific cosmetic concern. Regenerative therapies generally take a broader approach by focusing on the health and function of the skin itself.
This distinction is important. Rather than concentrating exclusively on visible signs associated with skin ageing, regenerative medicine seeks to support biological processes involved in skin maintenance and repair.
For some patients, this approach may align with a preference for gradual and natural-looking changes.
What Patients Can Expect
Most polynucleotide treatments involve a series of injections placed into targeted areas of the skin. Common treatment areas may include the face, neck, under-eye region and areas affected by acne scarring.
Following treatment, temporary redness, swelling or mild discomfort may occur. Treatment plans vary depending on individual circumstances, and practitioners may recommend multiple sessions where clinically appropriate.
Experiences and outcomes vary from person to person, and no specific result can be guaranteed.
The Future of DNA-Based Skin Regeneration
The growing interest in polynucleotides reflects a broader shift occurring throughout aesthetic medicine. Many patients are increasingly interested in prevention, maintenance and long-term skin health.
As research continues and new products enter the market, DNA-based regenerative therapies may play an increasingly important role within aesthetic practice.
Many industry observers believe the future of aesthetic medicine may place greater emphasis on supporting skin quality and healthy skin function rather than pursuing dramatic cosmetic change.
Frequently Asked Questions
Are polynucleotides the same as Rejuran?
No. Rejuran is one brand within the broader category of polynucleotide-based treatments.
Do polynucleotides add volume?
Polynucleotide-based treatments are generally used with the aim of supporting skin quality rather than creating volume in the way that dermal fillers are designed to do.
How long does it take to see results?
Any observable changes may occur gradually over several weeks or months. Individual responses vary.
Who may be suitable for treatment?
Suitability for any cosmetic procedure can only be determined through consultation with an appropriately qualified healthcare practitioner who can assess an individual’s circumstances, goals and medical history.
Final Thoughts
Polynucleotides have emerged as one of the more widely discussed developments in contemporary aesthetic medicine. Their growing popularity reflects increasing interest in regenerative approaches that focus on skin quality and long-term skin health.
As South Korea continues to influence global beauty trends, polynucleotide-based treatments are contributing to an evolving understanding of skin rejuvenation. Rather than focusing solely on immediate cosmetic change, regenerative therapies aim to support the skin’s natural repair processes and overall function.
