Rejuran (polynucleotide/PDRN skin therapy) is not a permanent “glass skin” treatment, but it can significantly improve skin quality when done correctly and in the right candidates.
What Rejuran actually does?
Rejuran is based on polynucleotides (PDRN) derived from salmon DNA. In aesthetic medicine, it is used to:
-
Improve dermal healing and skin regeneration
-
Support collagen remodeling over time
-
Strengthen skin barrier function
-
Reduce fine texture irregularities and early aging signs
Clinically, it is classified as a skin biostimulator, not a filler or instant glow treatment.
Does it create “glass skin”?
The “glass skin” effect people refer to is usually:
-
Smoother skin texture
-
More even tone
-
Subtle radiance from improved hydration and dermal quality
Rejuran can contribute to this effect, but:
-
Results are gradual (2–6 weeks after sessions)
-
It typically requires multiple sessions (commonly 2–4 sessions spaced weeks apart)
-
The improvement is quality-based, not cosmetic masking
So yes, it can help achieve glass-skin-like texture, but it is not an instant transformation.
Are results permanent?
No, results are not permanent.
-
Skin continues to age naturally
-
Environmental damage (sun, pollution, stress) continues
-
Collagen stimulation from PDRN is time-limited
Most patients maintain results for around 6–12 months, depending on:
-
Age and skin condition
-
Lifestyle and sun exposure
-
Maintenance treatments
Maintenance sessions are often recommended in aesthetic clinics.
How dermatologists view Rejuran
In clinical practice, Rejuran is considered:
-
A supportive regenerative treatment, not a standalone solution
-
Most effective for:
-
Early aging
-
Acne-scar-prone or damaged skin barrier
-
Fine texture irregularities
-
It is often combined with:
-
Laser treatments
-
Microneedling
-
Hydration boosters
Rejuran is not a permanent glass-skin creator, but a biological skin-quality enhancer. It improves how your skin behaves over time rather than giving an instant cosmetic filter effect.
If you expect permanent glowing, poreless skin from one treatment alone, that expectation is unrealistic. But it can produce natural, long-lasting improvement in skin texture and radiance.
