Rejuran has become one of Korea's most requested skin rejuvenation treatments. Many patients choose it to improve overall skin quality, support healing, and address concerns such as fine lines, rough texture, and reduced elasticity.
If you're considering Rejuran in Korea, this guide explains how the treatment works, who it may be suitable for, expected recovery, costs, risks, and how to choose a clinic.
What Is Rejuran?
Rejuran is an injectable skin rejuvenation treatment made from highly purified polynucleotides (PN), which are DNA fragments derived from salmon.
Unlike dermal fillers that primarily add volume, Rejuran is generally used to improve skin quality. The treatment is often chosen by patients looking for healthier-looking skin, improved texture, and enhanced skin recovery.
Because of its focus on skin regeneration rather than volume enhancement, Rejuran is sometimes referred to as a "skin booster."
How Does Rejuran Work?
Polynucleotides are believed to support the skin's natural repair processes.
After injection, Rejuran may help:
- Improve skin texture
- Support skin elasticity
- Improve hydration
- Reduce the appearance of fine lines
- Promote healthier-looking skin over time
Results develop gradually and often require multiple sessions.
Who Is Rejuran Suitable For?
Rejuran may be considered by patients who want to address:
- Fine lines
- Early signs of aging
- Dull skin
- Uneven texture
- Mild acne scars
- Reduced elasticity
- Overall skin quality concerns
It is often selected by patients who prefer a natural-looking improvement rather than dramatic volume changes.
