With so many Rejuran options, which one is best? How to Choose Skin Regeneration Therapy Using Polynucleotides (PN/PDRN)
My journey into aesthetic medicine stems from a desire to help enrich and beautify lives beyond simply treating illness. My specialties include hyaluronic acid, Botox, and thread lifts. I provide treatments that enhance each individual's unique qualities and bring out an elegant, natural beauty. For concerns around the eyes that are difficult to improve with dermatology alone, I also perform surgical procedures. By integrating dermatology and surgery, I holistically balance the entire face. With three periods of overseas study, I am also able to provide consultations in English.
Hello!
I am Ayuri Yokoyama, a cosmetic dermatologist and plastic surgeon.

Originating in Korea, Rejuran has enjoyed enduring popularity,
Lately, there are so many different types available, and I bet many of you are wondering which one is right for you!
1. What is Rejuran?
Rejuran is a product containing salmon-derived polynucleotides (PN/PDRN).Intradermal Skin Booster Treatmentis.

-
Improves microvascular blood flow and enhances the skin's regenerative environment.

Improves skin firmness, elasticity, and texture; reduces fine lines and pores. Source:Theme: Dermatology
In other words, not fillers like hyaluronic acid (volume-restoring treatments),
“Repair and enhance the skin itself”This is treatment aimed at achieving that.

Topical anesthesia (approx. 30 minutes) is applied before injection. The procedure itself takes about 10 to 15 minutes.
-
Downtime includes redness, unevenness, and minor bruising. Redness and unevenness usually subside by the next day. Bruising may last 1 to 2 weeks.

It does not take effect immediately; the effects gradually appear over a period of 4 to 8 weeks.
