Cellis Launches in the UK

After more than two and a half decades at the forefront of skin health, Debbie Thomas — widely regarded as the UK’s leading skin-focused laser and energy-based treatment expert - launches her long- awaited skincare brand: Cellis.

A precise, performance-driven edit grounded in clinical insight and built for everyday use, Cellis is where expert formulation meets real- world functionality. Born from Debbie’s 40,000+ hours of hands-on treatment experience (over 35,000 facials and advanced skin treatments performed), Cellis distils everything she’s learned about skin, how it behaves, heals, and thrives into a capsule range that’s as elegant as it is effective.

The name Cellis combines ‘cell’ and ‘dermis’ , reflecting the brand’s deep commitment to supporting skin health at a foundational, functional level where real transformation begins.

“Cellis is a direct response to what I’ve witnessed time and again in clinic: too many products, too much confusion and not enough real impact - or worse, irritation caused by poorly combined formulas. I created this range to simplify skincare without compromising on results. Because achieving healthy, glowing skin shouldn’t require guesswork or a 10-step routine, ” says Debbie.

Debbie Thomas is best known for pioneering combination treatments with technical precision and her no-nonsense approach with an empathetic, holistic delivery. Founded in 2009, her Chelsea-based D.Thomas Clinic is known as a go-to for high-performance skin solutions, trusted by a global, in-the- know clientele, celebrities, and the beauty press alike.

Cellis is the next evolution of that philosophy: a brand built not to sell routines, but to elevate skin function. These are formulas that prioritise barrier health, skin longevity and professional-grade results, without overwhelming your time, skin, or shelf.

“When too many products are layered, skin can become saturated by filler ingredients. This creates a barrier that blocks high-performance actives from penetrating effectively. Cellis takes a smarter approach: fewer, active-rich formulas that don't require layering. This way, actives reach where they're needed without competing for space” Says Debbie.

Cellis was born from decades of clinical insight and a belief that skincare should be both effective and intuitive. Every product in the Universal Edit, the brand’s core collection, is a multi-functional formula designed to replace several single-tasking products, without sacrificing results.

At launch, Cellis introduces four products designed to work across all skin types, tones, and concerns. This is not about layering endless actives. It’s about giving skin exactly what it needs, when it needs it, with the same intelligence and intention Debbie applies in-clinic. The range consits:

Cellis Everyday Cleansing Gelée

Cellis Everyday Cleansing Microfibre Cloths

Cellis Everyday C Complex
