Thanks for the question. A Rejuran treatment uses injectable polynucleotides to rejuvenate the skin, so it should work to improve the concerns which you have mentioned.
Even as a topical cream, polynucleotides were proven to improve skin elasticity and hydration.
As an injectable, two of their self-funded studies showed objective improvement to the skin in the form of:
1. Improved hydration
2. Reduced wrinkles and sagging
3. Improved pigmentation
4. Improved texture and skin tone
5. Skin repair and normalisation (thickening and improved skin function)
While both Rejuran and PRP can stimulate growth factors in the skin for rejuvenation and improvement, there have been no head to head studies comparing their efficacy against each other. I use PDRN (Rejuran is one brand of PDRN) in my practice currently, because PRP is still currently not approved for facial aesthetic use.
Apart from Rejuran or PRP, laser and skin treatments can improve skin texture and pore size from the first session as well. The choice of equipment and experience behind the operator are important factors behind the success of the treatment. I personally like combining Rejuran with these devices to give the most satisfactory results.
Hope this helps!
