Rejuran is a polynucleotide skin treatment, and the first thing a beginner wants to know is what the skin does afterward. The best answer comes from a study, not a sales page.
What one assessment found
The article at pmc.ncbi.nlm.nih.gov states: Most side effects were transient and classified as light in severity. That statement comes from a real-life assessment of injectable polynucleotides in aesthetic medicine for skin rejuvenation. Transient means temporary, but note the word most. It does not mean all, so a clinician still needs to hear about anything unusual.

The cheap step and the step that is not yours to judge
The cheap step is to write your questions down and to ask what to watch for after a session. Judging whether a reaction is normal is not a do-it-yourself matter, so tell your clinician rather than guessing.
Check with a clinician first
A licensed clinician near Hackettstown can tell you what applies to your skin. Asking first is how you stay in control of the decision.
