On Monday 20 April 2026, Miss Sherina Balaratnam welcomes Patrick Johnson, the inventor of Celluma, to the French Dining Room at Cliveden House for an exclusive morning masterclass and the official UK and European unveiling of a brand new Celluma device.
Some events happen once. This is one of them. S-Thetics Clinic has been appointed as the home of the official UK and European launch of a brand new Celluma device, with the inventor himself, Patrick Johnson, presenting it in person at one of England’s most extraordinary private houses.
The event takes place on Monday 20 April 2026 at Cliveden House in Berkshire, in the gilded surroundings of the French Dining Room. Tickets are available now at £50 per person, and spaces are strictly limited.
A UK and European First
Celluma LED light therapy has been a cornerstone of Miss Balaratnam’s regenerative protocols at S-Thetics Clinic for several years. Clinically validated and rooted in the science of photobiomodulation, it works at a cellular level, using specific wavelengths of light to stimulate mitochondrial activity, support tissue repair, and encourage the natural production of collagen and elastin.
S-Thetics is proud to have been chosen as the setting for the brand new device’s first appearance in the UK and Europe. Patrick Johnson will present it himself, in person, to a select group of guests. It is a genuinely rare occasion.
“This is not a product demonstration. It is a scientific event, in one of England’s most extraordinary private houses, with the man who invented the technology presenting it himself.”
MISS SHERINA BALARATNAM, MEDICAL DIRECTOR, S-THETICS CLINIC
Patrick Johnson: The Inventor of Celluma
Patrick Johnson has spent decades working at the intersection of advanced research and clinical medicine, translating the science of photobiomodulation into real-world protocols used in practices worldwide. As the inventor of Celluma, he helped bring clinically used LED light therapy into mainstream care, supporting skin health, recovery, and regeneration by harnessing the body’s own cellular response to specific wavelengths of light.
Widely regarded as one of the world’s foremost authorities on low level light therapy, Patrick is known for making complex science practical. At this event, he will share the origins of Celluma, the science that underpins it, the latest clinical applications, and the vision for where light-based medicine is heading. Questions are warmly encouraged throughout.
