It's okay.
Color: PDRN 25%
I'm not going to say it's good I'm not going to say it's bad, I do not like the sticky feeling you have to wash your hands afterwards. And it feels sticky on your face for a while I used it about 10 minutes after microneedling my face. It did help my face feel better kind of calm it down a little bit. When I applied it it didn't burn or nothing

Great booster to mix with other products — long-term results are real
Color: PDRN 25%
The Salmon DNA PDRN 250,000 ppm Concentrate Booster works amazingly well when mixed with other skincare products. I often add a few drops to my cream, essence, or even a mask, and it blends in smoothly without changing the texture. It’s super versatile and easy to incorporate into any routine.
At first, I didn’t notice a dramatic change right away, but after consistent use, I can definitely see a difference. I’m already on my third bottle since I started using it back in Korea, and my skin texture has improved a lot. The bumps and unevenness have noticeably reduced, and my skin feels much smoother and more refined now.

Results after a few uses. ✨
Color: PDRN 25%
There’s a little bit of magic in this bottle. I’ve applied directly to skin, let it soak in for a few minutes, then follow with moisturizer with no issues. Already seeing subtle softening and fluffing of lines after a few uses. Excited for this one. Thank you!
