Rejuran I in Gangnam, Seoul
ïŧŋAdvanced Under-Eye Rejuvenation at Cheongdam 4.4 Skin Clinic
Rejuran I is a specialized polynucleotide (PN) skin rejuvenation treatment designed specifically for the delicate under-eye area. Derived from highly purified salmon DNA fragments, Rejuran I helps support skin repair, improve elasticity, enhance hydration, and reduce the appearance of fine lines and dark circles without adding volume like traditional fillers. At Cheongdam 4.4 Skin Clinic in Gangnam, Seoul, Rejuran I treatments are customized according to individual under-eye concerns, helping patients achieve smoother, healthier, and more refreshed-looking eyes through gradual skin regeneration and collagen stimulation. Rejuran I is formulated with a lower viscosity than standard Rejuran products, making it particularly suitable for the thin skin around the eyes.
ð What Is Rejuran I?
Rejuran I is an advanced skin booster treatment developed specifically for the delicate eye area. It contains highly purified polynucleotides (PN), which help support cellular repair, collagen production, hydration, and skin regeneration. Unlike dermal fillers that primarily restore volume, Rejuran I focuses on improving skin quality and strengthening the skin from within.
The under-eye region is one of the first areas to show signs of aging due to its thin skin and constant movement. Fine lines, dark circles, crepey texture, and reduced elasticity often become noticeable over time. Rejuran I is designed to address these concerns by supporting the skin's natural healing and renewal processes.
At Cheongdam 4.4 Skin Clinic in Gangnam, Seoul, Rejuran I treatments are tailored according to skin condition, under-eye anatomy, and rejuvenation goals to promote long-term skin improvement.

âĻ Benefits of Rejuran I
Improved Under-Eye Skin Quality
Rejuran I focuses on improving the overall health and quality of the skin beneath the eyes. Many patients notice smoother and healthier-looking skin after completing a treatment series.
Enhanced Skin Elasticity
Polynucleotides help support collagen and elastin production, which may improve skin firmness and resilience over time. This can contribute to a more youthful under-eye appearance.
Reduction of Fine Lines
As skin quality improves, fine lines and crepey texture around the eyes may become less noticeable. Results develop gradually through ongoing skin remodeling and regeneration.
Better Hydration
Rejuran I helps support skin hydration and barrier function, contributing to healthier and more refreshed-looking skin around the eyes.
Improvement of Dark Circles
Many patients seek Rejuran I for concerns related to dark circles and tired-looking eyes. Improved skin thickness and quality may help reduce the visibility of under-eye shadows.
