Rejuran is a cosmetic treatment typically referring to the use of a skin regenerative product containing peptides and growth factors. The key component of this product is Polydeoxyribonucleotide (PDRN), a substance extracted from fish DNA. The primary purpose of Rejuran is to stimulate skin regeneration and repair, contributing to the improvement of skin texture, slowing down signs of aging, and providing hydration and nourishment.

Rejuran treatments are typically administered through injections, introducing a solution containing PDRN into the deeper layers of the skin. This process stimulates the production of collagen and elastin proteins, enhancing skin elasticity and radiance. This treatment is believed to have positive effects on reducing fine lines, improving skin tightness, and promoting overall skin health.
