Built by scientists. For skin that's been through the most.
Since 2018, RSL Revolutionary Laboratories has formulated skincare for the moments most brands ignore — when skin is dry, sensitive, recovering, or just very, very tired.
Our formulas are developed in our own laboratory in Cyprus, with ingredients chosen for tolerance first and performance second — a philosophy especially valued by people whose skin doesn't tolerate much.
Every formula is tested in our lab for skin tolerance and stability before it reaches a single customer. Each one draws on a small, tightly considered ingredient list — including hyaluronic acid, panthenol, and hydrolysed collagen — chosen for how well compromised skin tolerates them.
Why we started the lab
εὖSKIN was born from a personal experience.
After Dr. Marianna lost her sister to ovarian cancer, she watched the toll that long, difficult treatments take on skin — and how few products felt safe to use.
That experience shaped how the lab works to this day: every formula is built around tolerance, around what compromised skin can handle, around what feels comfortable in a difficult moment.
The team behind εὖSKIN
εὖSKIN is built on the work of Dr. Marianna Prokopi-Demetriades — a biochemist with a PhD from King's College London, a Forbes 20 Women in Tech honouree, and the founder of three biotech ventures
across oncology and skincare. She co-leads the lab with Dr. Anna Christofini, an immunology and microbiology specialist whose work shapes our formulation philosophy from the ground up.
Their partnership has been recognised internationally — the Cyprus Research Award, the GWTA Founder Award, the King's College London Distinguished Alumni STEM Award, Madame Figaro's Woman of the Year. But the work that matters most to them is quieter. It happens in the lab, on the bench, where formulas are tested, retested, and rejected until they meet the standard skin at its most reactive deserves. We work very closely with patient associations, clinics, hospitals, to try to solve the challenges of doctors and their patients.
Skincare for skin that's been through it
We believe the best care is the most considered. Every εὖSKIN formula starts with a short, deliberate ingredient list — and a question:
Will skin at its most reactive tolerate this?
Performance is the second question, never the first.
Made in our laboratory in Cyprus
Every εὖSKIN formula is developed and produced in our own laboratory by a team led by working scientists.
Our group has a vast experience in cancer research, but also the manufacturing and production of biomaterials like collagen, especially for the bioprinting of artificial organs and wound management solutions.
We pair botanicals chosen for low reactivity — gynura, ganoderma, calendula — with cosmetic ingredients that have long histories of tolerance, like hyaluronic acid, panthenol, and hydrolysed collagen.
The result is skincare that feels comfortable on skin that's stopped tolerating most things.
