What it is
Rejuran is a polynucleotide injectable. Polynucleotides are chains of nucleotides, and the ones used here are PDRN derived from purified salmon DNA. They are placed superficially in the dermis rather than deep for structure, because the target is the condition of the skin itself.
Rejuran is not a filler and not a botulinum toxin. It does not add volume, and it does not relax muscle. If your concern is a hollow cheek or a movement line, a different treatment is the right answer and your doctor will say so at assessment.
