A Swedish laboratory.
Five formulas, unchanged.
Transderma was born in a Stockholm laboratory in 1998, the applied form of twenty-five years of research by Dr. Klaus Alvin Ronlán (Docent, Ph.D.), Professor of Bio-Organic Chemistry at the University of Lund. The answer was five serums. They haven't changed since.
Founder of Transderma, 1998
A problem worth
solving once.
Born in Copenhagen in 1942, Dr. Klaus Alvin Ronlán was a bio-organic chemist who spent twenty-five years at the University of Lund studying how antioxidants and vitamins behave in the skin, and how to deliver them past the surface into the layers where they do biological work. His research produced over 58 peer-reviewed papers and a portfolio of international patents.
He also founded Alron Chemical, a Swedish laboratory applying bioorganic chemistry to environmental problems: natural organic micro-organisms that safely degrade toxic waste in water and soil. It was a natural step for the same laboratory to turn its attention to skin biology. Transderma was born there in 1998.
"We don't add more — we remove everything unnecessary."
The science found its second half in Graziella Gallelli, a skincare entrepreneur whose instincts for application, use, and people complemented Dr. Ronlán's chemistry. Together they translated the laboratory work into five serums that replaced entire multi-step routines with a handful of functional ingredients each.
From the beginning, the serums lived in the medical and aesthetics community: tested in Dr. Katsuya Takasu's plastic-surgery clinics in Japan, distributed in Taiwan by Tanabe Pharmaceuticals, carried in Stockholm at Nordiska Kompaniet, and approved by the Swedish Medical Product Agency (Läkemedelsverket). When customers outside the clinics began asking where to buy, we added a website. We didn't change the formulas.
Three decades,
quietly.
Ph.D., Royal Institute of Technology, Stockholm
Dr. Ronlán earns his Ph.D. at the Royal Institute of Technology in Stockholm, following a B.Sc. at Copenhagen and an M.Sc. at Uppsala.
Doctor of Science, University of Lund
A second doctorate, Doctor of Science, from the University of Lund — where he becomes Professor of Bio-Organic Chemistry. The work produces over 58 peer-reviewed papers and international patents in antioxidant chemistry and transdermal delivery.
Alron Chemical — research leaves the university
Dr. Ronlán founds Alron Chemical Co AB in Sweden and Alron Japan the same year — labs that apply his bio-organic research beyond the academy. A 1982 Visiting Professorship at UC Santa Cruz, applying early AI to biochemistry, adds the systems-level thinking that later shapes Transderma's formulations.
Transderma is born in the laboratory
Dr. Ronlán and Graziella Gallelli release five serums (C, A, O, M, R) from Stockholm — a complete system from day one, built for the medical and aesthetic community.
The first direct-to-consumer relaunch
For nearly three decades, Transderma sold quietly through word of mouth, modeling agents, and clinical offices. The first true direct-to-consumer push: same five serums, same airless bottles, finally open beyond the clinic.
The serums that started it all —
and haven't changed since.
The Discovery Kit contains pocket-size versions of all five serums. It's how most of our long-term customers first found us.
