In the world of regenerative aesthetics, few treatments have generated as much excitement as Rejuran. Originally developed and perfected in South Korea, Rejuran has earned a reputation as one of the most effective treatments for improving skin quality, restoring a youthful glow, and stimulating the skin’s natural healing processes.
Unlike traditional fillers that focus on replacing lost volume or Botox treatments that relax facial muscles, Rejuran works differently. It targets the health of the skin itself, helping to repair damaged tissue, stimulate collagen production, and improve overall skin quality from within.
Patients throughout Brooklyn and New York City are increasingly interested in Rejuran because of its ability to create subtle, natural-looking improvements that continue to develop over time.
One of the most common questions we hear at Aesthetic Island is:
“What do Rejuran before and after results actually look like?“
The answer is that Rejuran delivers gradual, progressive improvements rather than dramatic overnight changes. The treatment focuses on healthier, stronger, smoother skin rather than altering facial structure.
In this guide, we’ll explore what you can realistically expect from Rejuran before and after treatment, how long results take to appear, who is a good candidate, and why this innovative treatment is becoming one of the most sought-after skin rejuvenation procedures available today.
What Is Rejuran?
Polynucleotides are DNA fragments that help support cellular repair and tissue regeneration.
The DNA used in Rejuran is derived from salmon DNA, which has been shown to be highly biocompatible with human tissue.
Rather than simply filling wrinkles or adding volume, Rejuran helps:
Stimulate collagen production
Improve skin elasticity
Enhance hydration
Strengthen the skin barrier
Support tissue repair
Improve skin texture
This regenerative approach is what makes Rejuran unique among injectable treatments.
Why Rejuran Before and After Results Look Different Than Fillers
Many patients are surprised by how different Rejuran results appear compared to dermal fillers.
Dermal Fillers
Fillers typically create:
Immediate volume
Instant contour improvement
Visible correction right after treatment
Rejuran
Rejuran focuses on:
Skin health
Cellular regeneration
Long-term rejuvenation
Collagen stimulation
Because Rejuran improves the skin itself, results develop gradually and often appear more natural.
Patients usually notice that their skin simply looks healthier, brighter, smoother, and younger.
What Concerns Does Rejuran Treat?
Rejuran is often used to improve a variety of common skin concerns.
Fine Lines and Wrinkles
By stimulating collagen production, Rejuran can soften early signs of aging.
Dull Skin
Many patients notice improved radiance and brightness.
Uneven Texture
Rejuran helps smooth rough skin and improve overall texture.
Enlarged Pores
Improved skin quality may reduce the appearance of pores.
Acne Scars
Some patients experience noticeable improvements in acne-related skin damage.
Under-Eye Aging
Rejuran is frequently used beneath the eyes to improve:
Crepey skin
Fine lines
Skin thickness
Skin Elasticity
Patients often report firmer, healthier skin over time.
Rejuran Before Treatment: What Patients Typically Notice
Before undergoing treatment, many patients have concerns such as:
Fine lines around the eyes
Dull complexion
Loss of skin elasticity
Uneven texture
Early aging changes
Dehydrated skin
Mild acne scarring
These issues may not necessarily require fillers or surgery, making Rejuran an attractive option.
What Happens During a Rejuran Treatment?
The treatment process is relatively straightforward.
Consultation
Your provider evaluates:
Skin quality
Medical history
Treatment goals
Areas of concern

The skin is cleansed and numbing cream may be applied.

30 to 45 minutes

Unlike fillers, which provide instant correction, Rejuran works gradually as the skin regenerates.
Immediately After Treatment
Patients may experience:
Mild redness
Small injection bumps
Slight swelling
These effects typically resolve within a few days.
One Week After Treatment

Improved hydration
Softer skin
Healthier appearance
The skin often begins to feel smoother.
Two to Four Weeks After Treatment
This is when many patients start noticing visible changes.
Common improvements include:
Better skin texture
Increased radiance
Improved hydration
Reduced dullness
Six to Eight Weeks After Treatment
Collagen production continues to increase.
Patients often notice:
Firmer skin
More even tone
Improved elasticity
Reduced fine lines
Three Months and Beyond
This is often when the most dramatic improvements become visible.
The skin may appear:
Healthier
Brighter

How Many Rejuran Sessions Are Needed?
Most providers recommend a series of treatments.
A common treatment plan includes:
Three sessions
Approximately four weeks apart
This allows collagen production and regeneration to build progressively.
After the initial series, maintenance treatments may be recommended.
Why Multiple Sessions Produce Better Results
Each treatment builds upon the previous one.
The regenerative process is cumulative.
Multiple sessions often lead to:
Greater collagen production
Better skin repair
Longer-lasting outcomes
Patients who complete the full treatment series typically experience the most significant improvements.
