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!

Helped Tighten My Skin & Minimize Pores
Color: Cyano Pink Spicule, Color: Cyano Pink Spicule
I’ve loved the Dr. Melaxin Cyano Pink Spicule Serum! The bottle is small, but it lasted me around 6 months since I only use one pump every other night. When I first started using it, I noticed a tingling sensation, but over time my skin adjusted and I barely notice it now. I’ve definitely seen my pores appear smaller and my skin feels tighter and smoother after using it.

Great for pore reduction
Color: Cyano Pink Spicule
This product works great!! it almost feels like an exfoliator. It reduced the pours on my nose, which were very big and now you can barely see them. I would recommend this product if you have large pores also make skin look firmer and smoother more for a night cream though.
