It works by activating the skin's own regenerative ability to restore its own collagen structure and increase skin elasticity.  This allows your skin to recover with a course of 3 treatments with intervals of 2-4 weeks between sessions, followed by a treatment every 6-12 months to nurture a healthy skin condition.

Rejuran is generally considered safe when performed by a trained and qualified professional. It uses polynucleotide (PN) derived from salmon DNA, which has a similar structure to human DNA, making it biocompatible and well-tolerated by the skin. The treatment is minimally invasive, and side effects are typically mild, including temporary redness, swelling, or bruising at the injection site.

However, as with any cosmetic procedure, there are some risks, such as allergic reactions, infection, or uneven results. It is important to undergo Rejuran treatments under the supervision of a licensed dermatologist or aesthetic practitioner to ensure safety and effectiveness. Always consult with a healthcare provider before undergoing any skin treatment.
