What is Rejuran?

Rejuran is a product family. The formula discussed here is Rejuran Healer, documented as sodium polynucleotide 20 mg/mL (2% PN) for facial skin-quality and fine-line assessment. Other Rejuran variants can differ, so the box, formulation and treatment area must be confirmed before injection.

Rejuran has direct clinical publications going back at least to a 2014 phase III split-face trial, plus later randomized comparisons. A 2024 systematic review still judged the wider injectable-PN evidence as low to moderate quality and heterogeneous. This is a stronger publication history, not a promise that Rejuran will outperform another 2% PN product for every person.

How it works

Why it may help

Why Rejuran

• ✦Rejuran Healer is documented at 20 mg/mL (2% PN)
• ✦Direct randomized Rejuran studies have been published since at least 2014
• ✦Focuses on facial fine lines and skin quality rather than structural volume
• ✦Evidence is presented with study size and limitations, not as a guaranteed result

Published evidence

Why Rejuran is the evidence-led option

Evidence level: strong for the existence of randomized comparisons, moderate for predicting an individual skin-quality result. Study formulation, area and technique may not match every clinic protocol.

A doctor may consider it for

• —Facial fine lines or early textural change
• —A skin-quality goal rather than structural reshaping
• —Able to accept temporary injection bumps, redness or bruising
• —Understands that published PN evidence does not guarantee an individual result

On the day and afterwards

After confirming the named formulation and treatment area, the physician plans the injection depth and pattern. Topical anaesthetic may be used. Session time and the number of visits depend on the area, technique, response and treatment goal rather than a fixed package.

Small bumps, redness, swelling, tenderness or bruising may last from hours to a few days. Follow the clinic’s guidance on cleansing, skincare, make-up, exercise and when to seek medical review.

When changes may appear

Any skin-quality change should be assessed gradually with comparable photographs and follow-up rather than judged from temporary post-injection swelling. The need for another session depends on response, side effects and the original goal.

Everyone responds differently. Before treatment, your doctor will examine the area and talk through a plan that makes sense for you.
