I peeled off my slug-vaseline face at 2AM and injected my skin with fish DNA instead. Dramatic? Sure. But my dehydrated cheeks have been silently screaming for years and thick creams just sat on top like a wet blanket.
The real flex here is that PDRN doesn’t sit on anything—it goes *in*, and that changes the entire game for dry skin that drinks up serums and still feels like sandpaper by noon.
It’s a 2.5ml vial of polynucleotides (salmon DNA, yes really) that you get injected or microneedled into the dermis. Clinics charge $150-$300 per session, and the claim is that it physically rebuilds your skin’s moisture barrier from the inside out.
Salmon DNA Extract
Binds to your fibroblasts and tells them to get off their lazy asses and make collagen
Low Molecular Weight HA
Pulls water into the skin at a depth that topicals physically cannot reach
Wound-Healing Response
The micro-trauma of the needling itself triggers your skin’s own repair cascade

It’s not a cocktail—it’s a single-molecule hero. And that’s the point. Rejuran doesn’t throw 47 extracts at you; it gives your skin the raw material to fix its own plumbing.
- PDRN (Polynucleotide): Repairs damaged cells and boosts collagen production
- Hyaluronic Acid: Carries 1000x its weight in water deep into tissue
- DMAE: Firms and tightens the skin matrix
- Amino Acids: Building blocks for a healthier lipid barrier

The texture is a watery gel that feels like nothing—the needle is the memorable part. It’s a 20-minute session of tiny pricks that feel like an angry cat kneading your face. Then you look like a sunburned tomato for 6 hours.
Week two hit different. My makeup stopped separating around my nose by 3PM. That tight, “I’ve been in a desert” feeling after washing my face? Gone. It’s subtle until it isn’t—by week 3, my skin holds onto moisture like it’s got somewhere to be.

My forehead lines didn’t vanish and my pores still exist. But my skin’s baseline went from “dehydrated crinkle” to “normal person who drinks water.” The plumpness is real, and it lasts about 4-5 months before you need a top-up.

It’s not a miracle—it’s a repair job. If your skin is a sponge that won’t hold water, this gives it the structure to finally soak it up.
