What is Rejuran S?
Rejuran S is a skin booster whose main ingredient is polynucleotide (PN) purified from salmon DNA. Unlike general skin boosters that are spread broadly across the face, Rejuran S is made to be injected locally into areas of concentrated damage such as scars and enlarged pores. Because PN has a structure similar to human DNA, its biocompatibility is considered high, and Rejuran S is formulated with a higher viscosity so that it stays longer within depressed scar areas.
How it works
Rejuran S is injected directly into the dermis, where the PN stimulates fibroblasts and encourages the synthesis of collagen and elastin. Its high viscosity also acts as a physical scaffold that supports the collapsed tissue beneath a scar, helping the skin regenerate over time. Results build up gradually over several weeks rather than appearing all at once, and individual results may vary.
Key benefits
- Improvement of depressed acne scars such as rolling and boxcar types
- Refinement of enlarged pores and rough skin texture
- Localized support of volume and elasticity through dermal regeneration
- Reinforced density in thinned skin around the eyes and mouth
- Strengthened natural recovery capacity with repeated sessions
Recommended for
- Those bothered by long-lasting acne scars or depressed marks
- Those who felt general skin boosters did little for scarred areas
- Those who find the downtime of laser treatments burdensome
- Those who want to improve enlarged pores and uneven texture together
- Those who want intensive care focused on specific areas
Rejuran S at Seye Clinic
Because Rejuran S is highly viscous, its results and recovery depend on where and how much is injected. Our medical team first checks the depth of the scars, the condition of the pores, and the thickness of the skin, then injects an appropriate amount only where it is needed. Rather than pushing for excessive sessions or volume, we review your response and recovery after each treatment and adjust the plan for your next session together with you.
