Have you ever looked in the mirror and felt like your skin just lost its… bounce? That was me a few months ago. Despite religiously applying my 10-step skincare routine, my complexion looked tired, and my pores seemed to be multiplying. I knew I needed something more than just topical creams. That’s when I stumbled upon a treatment everyone in the K-beauty world is raving about: the Rejuran injection. \ud83d\ude0a<\/p>\n
To be honest, the idea of needles scared me, but the promise of achieving that coveted “glass skin” from within was too tempting to pass up. Today, I want to share everything I’ve learned about this fascinating treatment, straight from the dermatologist’s chair to you!<\/p>\n
<\/p>\n
At its core, a Rejuran injection (often called Rejuran Healer) is an advanced skin booster. But unlike traditional fillers that use Hyaluronic Acid to simply plump the skin, Rejuran uses something called Polynucleotides (PN)<\/strong>. Now, what are PNs? They are basically DNA fragments extracted from wild salmon!<\/p>\n Instead of just masking the signs of aging, Rejuran actually goes into the dermal layer and repairs damaged skin cells. It’s like sending tiny construction workers into your skin to rebuild the collagen and elastin foundations. Pretty amazing, isn’t it?<\/p>\n <\/p>\n So, what can you actually expect after getting poked with salmon DNA? I think the biggest draw is that the results look incredibly natural. You won’t look like you’ve “had work done”\u2014you’ll just look like you sleep 10 hours a night and drink a gallon of water daily.<\/p>\n As you can see, Rejuran shines in the “healing” department. It specifically targets fine lines, enlarged pores, and overall skin dullness. It was totally life-changing for my rough skin texture!<\/p>\n<\/div>\n Let’s address the elephant in the room: the pain. If you’ve been researching Rejuran, you’ve probably heard that it stings. And I won’t sugarcoat it\u2014it was totally annoying. Because the PN solution is quite thick, injecting it into the skin causes a distinct burning sensation.<\/p>\n Most clinics apply a strong numbing cream for about 30 to 45 minutes beforehand. If you have a low pain tolerance, definitely ask your doctor if they offer laughing gas or if they can inject it using a mesogun (an automated injector) instead of manual injections, as it can distribute the product more evenly and quickly.<\/p>\n <\/p>\n Rejuran isn’t a “one and done” magic wand. Because it fundamentally regenerates your skin cells, it takes time and consistency. I highly recommend trying out this quick calculator below to see a general estimate of what you might need based on your age.<\/p>\n\ud83d\udca1 Tip: Why Salmon DNA?<\/strong>
You might be wondering, “Why salmon?” It turns out that salmon DNA is highly biocompatible with human skin<\/span>. This means our bodies readily accept it, minimizing the risk of allergic reactions and maximizing the regenerative effects.<\/div>\nWhy Everyone is Obsessed: The Benefits \u2728<\/strong><\/h2>\n

\u26a0\ufe0f Warning: The Embossing Effect<\/strong>
Immediately after the procedure, your face will look like it has been attacked by a swarm of mosquitoes. These small bumps are called “embossing” and are completely normal. They usually subside within 48 to 72 hours, so plan your social calendar accordingly!<\/div>\nHow Many Sessions Do You Need? \ud83d\uddd3\ufe0f<\/strong><\/h2>\n
