DR. TIMM GOULEKE

Written by LENA RAFF

Dr. Timm Gouleke, or “Dr. Timm” as he is affectionately known around VIOLET GREY HQ, is not only an exceptionally studied, prolific dermatologist with his own Munich clinic and international certifications, he uses his education and firsthand patient experience to inform the creation of the products in his brand: Royal Fern.

The refined line of skin care essentials—much like Dr. Timm himself, who trained both traditionally and in the field of natural medicine—draws from the most effective and proven ingredients found in nature while staying on the cutting-edge of modern technology. His latest offering stays true to this philosophy with a formula inspired by the regenerative treatments performed in his practice, harnessing the power of a buzzy and clinically tested natural ingredient: polynucleotides or PDRN. We sat down with the good doctor to learn more about his new PN Boosting Serum.

WHAT WAS THE INSPIRATION BEHIND THIS PRODUCT?

The inspiration came directly from what I see every day in my dermatology practice: patients are increasingly interested in regeneration. Polynucleotide-based treatments have become an important part of my approach to patient care. They are particularly beneficial for individuals who want to enhance their skin quality, improve elasticity, and restore a healthy, vibrant appearance. I consider them a key element of modern regenerative aesthetics, focusing on stimulating the skin’s own ability to repair, rebuild, and renew itself rather than simply covering up or temporarily softening the visible signs of aging. With the PN Boosting Serum, my goal was to translate the science behind in-clinic regenerative treatments into a sophisticated at-home formula that strengthens the skin, improves resilience, and supports healthy aging in a gentle but effective way.

WHAT MAKES POLYNUCLEOTIDES SUCH AN EXCEPTIONAL INGREDIENT, AND WHAT DO THEY DO FOR THE SKIN?

Polynucleotides are remarkable because they work at the cellular level to support skin regeneration. They help stimulate fibroblast activity, boost hydration, and promote tissue repair. In everyday terms, this translates to stronger skin, smoother texture, and a healthier, more radiant appearance. Their anti-inflammatory properties also make them suitable for sensitive or stressed skin. I see them as a powerful ally in enhancing the skin’s natural ability to restore and rejuvenate itself. It’s perfect for Skin Longevity.

HOW DO THEY WORK DIFFERENTLY AT HOME VS. IN A “SALMON SPERM FACIAL”?

In-clinic polynucleotide treatments allow the active ingredient to be delivered deeper into the skin through precise injections, creating a more intensive and targeted regenerative response. An at-home serum, on the other hand, works within the upper layers of the skin and is formulated to provide steady, long-term support.

The PN Boosting Serum also beautifully complements professional treatments, helping prolong and maintain results as well as reinforcing the skin barrier and continuously encouraging regeneration between appointments. It’s about building a true synergy between in-clinic procedures and everyday skincare, ensuring the skin is consistently supported from every angle.

HOW DO POLYNUCLEOTIDES INTERACT WITH THE OTHER INGREDIENTS IN THIS SERUM, AND WHAT IS THE RESULT?

This serum is designed to create the perfect environment for polynucleotides to work at their peak. They’re combined with Bio Placenta (a peptide complex that mimics placenta’s regenerative effects on the skin) and carefully chosen hydrating and barrier-supporting ingredients that boost skin repair and enhance its natural regenerative processes. Bio Placenta contributes extra nourishment and revitalization, helping support cellular renewal and overall skin vitality. Together, these ingredients maximize the regenerative benefits while keeping the formula gentle and refined. The result is skin that feels deeply hydrated, smoother, and more resilient, with noticeable improvements in tone, texture, and radiance over time.

WHO IS A GOOD CANDIDATE FOR THIS SERUM?

I recommend this serum for anyone looking to actively support skin regeneration and maintain healthy, youthful-looking skin. It’s especially helpful for those noticing early signs of aging, experiencing skin stress, or dealing with sensitivity. Thanks to its soothing and restorative properties, it’s also perfect for use after aesthetic treatments or during times when the skin needs extra care. Overall, it’s a versatile addition to most skincare routines and provides benefits for a wide variety of skin types.
