Rejuran is derived from salmon DNA, biocompatible with human skin and has healing properties. 

Here are a few reasons why it’s trendy in Korea:

1. Anti-Aging and Skin Repair: Rejuran helps with skin repair at the cellular level, improving elasticity and texture, reducing fine lines, and enhancing skin hydration. This is appealing in Korea, where anti-aging treatments and maintaining youthful skin are highly valued.
   
   
   

2. Natural Ingredients: Salmon DNA, also known as polynucleotide (PN), is known for promoting skin regeneration. This natural element attracts those looking for less invasive, safer skincare options.
   
   
   

3. Quick Recovery and Minimal Side Effects: The injections are minimally invasive with relatively low downtime, making them convenient for busy lifestyles. Side effects are generally mild and manageable, adding to its appeal.
   
   
   

4. Focus on Skin Quality: Korean beauty standards often emphasize skin texture, brightness, and overall quality rather than just wrinkle removal. Rejuran aligns with this focus, providing subtle improvements in skin quality rather than dramatic changes.
