Rejuran comes up often in polynucleotide talk, and beginners reasonably want to know what is in it before anything else.
The ingredient in plain words
hauteliving.com says Rejuran is composed of polydeoxyribonucleotides, otherwise known as PDRNs, which is the short name to remember.
Where to read more at no cost
Reading what has been published costs nothing. Start with the Dermatology Times article polynucleotide therapy shows promise in scar and burn management. Two papers are a real-life assessment of injectable polynucleotides high purification technology in skin rejuvenation and a prospective observational study of polynucleotide injections for periorbital rhytides.
What is not for you to decide alone
Knowing the ingredient name does not tell you whether it suits you. That judgment, and any injection, belongs with a trained provider and not with a home kit or a guess.
Take the ingredient name to a clinician
Put that ingredient name on your question list and ask a licensed clinician what it means for your skin. Asking an ingredient question is a simple way to begin.
