Claims Insights

Challenging Views Beyond the Adjectives

Cosmetic claims sit at an interesting intersection of science, regulation, marketing and consumer expectations. They have been central to my work for many years — and continue to offer plenty to think and write about.

Claims Insights brings together my articles, commentary, interviews and other contributions on cosmetic claims, substantiation and the wider issues affecting our industry.

The subjects range from study design and scientific evidence to emerging technologies, shifting consumer expectations and regulatory developments. I also explore some of the more difficult questions surrounding claims: what constitutes meaningful evidence, where innovation ends and marketing begins, and whether the claims we make genuinely reflect what the science can support.

The collection is continually updated as new issues emerge and the cosmetics industry evolves. These are not intended to provide all the answers.

Sometimes the most useful contribution is simply to ask a better question.

The Curious Man

In this episode, we’re joined by Dr. Theresa Callaghan, skincare scientist of 35 years and author of Help! I’m Covered in Adjectives: Cosmetic Claims & The Consumer. With wit, science, and decades of industry experience, Dr. Callaghan helps us unpack the seductive language of the beauty industry—revealing how terms like “clinically proven” and “anti-aging” are often more about persuasion than proof. From scientific credibility to regulatory blind spots, this conversation is a must-listen for anyone who buys (or sells) cosmetics, including men.

Recent Expertise Interviews and Opinions

EuroCosmetics | Opinion Piece, April (4) 2026: Is It Time for the EU Cosmetics Industry to Recategorise Itself?
Does the current broad, unified category of “cosmetics” still reflect the scientific, technological, environmental, and perceptual realities of 2026? Or is structural re-categorisation now required to preserve legitimacy and strategic resilience?
tks | HPC Today: Many of the challenges currently facing the cosmetic industry are not isolated problems but symptoms of a broader change in values and priorities. Rather than viewing concerns such as exaggerated claims, declining scientific rigour, misinformation and increasingly compressed product development timelines as separate issues, I suggest they should be understood as interconnected outcomes of wider structural and cultural shifts.
