Tested for you: Polynucleotides in Royal Fern’s “PN Booster Serum”
Polynucleotides, or PN for short, represent the new generation of skin regeneration at the cellular level. In dermatological practice, they are already a proven treatment for restoring skin vitality and repairing cellular damage.
What exactly are polynucleotides?
Polynucleotides are naturally occurring molecules found in our cells. These long polymers, consisting of many interconnected nucleotides, are the building blocks of DNA/RNA, i.e., the carriers of genetic information. They play a crucial role in cellular repair and regeneration processes. For use in aesthetic medicine, polynucleotides are obtained from processed natural sources such as fish DNA. They stimulate the production of collagen and elastin and can be used to treat scars and improve skin structure.
Biostimulating skin care
Munich-based dermatologist Dr. Timm Golueke has incorporated this renewal principle into a serum for his Royal Fern skincare line. He was inspired to do so by the positive experiences he has had with polynucleotide treatments in his practice.
This innovative facial serum is based on specialized polynucleotides and effective bio-stimulators that revitalize the skin and strengthen it from within. When used regularly, the serum improves skin elasticity, restores tissue firmness, and refines the skin’s structure over time. A blend of antioxidants, including the patented Royal Fern Complex, protects againstfree radicals, while carefully selected enzymes strengthen the skin’s barrier function.
“PN Boosting Serum marks a new era in proactive skin rejuvenation,” says Dr. Timm Golueke, dermatologist and founder of Royal Fern. “With its unique combination of polynucleotides and biostimulating ingredients, this formula not only addresses the visible signs of aging, but also strengthens the skin so that it can regenerate from within.”
Lightweight and intensely nourishing
The serum is transparent and light, and comes in a salmon-colored dispenser. Nevertheless, it provides intensive care. I was able to integrate it into my usual skincare routine without any problems. It absorbs quickly, is non-greasy, and is economical to use. And who wouldn’t want to benefit from the new polynucleotide science when the result is visibly smoother, firmer, and more resilient skin?

To travel during my profession as a beauty journalist was never enough for my. Also my six month on a world trip didn’t do it. It always attracts me to other cities, foreign countries, on roadtrips and places I don’t know yet. But I am not only interested in “culture” and “cream”, I am also fascinated by people who have stories to tell . Such unique experiences I want to share with you.
