Interview With Skincare Scientist About Her Authoritative Book On Cosmetic Product Claims

 



1.     What is your book, Help! I’m Covered in Adjectives: Cosmetic Claims & The Consumer – Navigating Science, Regulations, and Myths in the Beauty Industry, 2nd Edition, about?

 

It’s an insightful exploration of what cosmetic claims are, how they are made, the regulations behind them, and how they are developed and substantiated. It examines the anatomy of claims, the science behind substantiation, and the challenges faced when developing regulatory compliant claims. It helps to demystify the complex language used in product marketing. This second edition offers updated content, including discussions on misinformation, greenwashing, and the role of influencers, consumers, and even journalists in shaping consumer misconceptions and perceptions. As a resource it has value for consumers seeking to navigate the beauty industry with greater awareness, as well as for professionals in marketing, research and development, and regulatory affairs aiming to deepen their understanding of cosmetic claims and their implications.

 

2.     What inspired you to write it?

 

In spring 2019, at the In-Cosmetics Global Meeting in Paris, I hosted my annual workshop on claims development. The delegates were eager to learn the 'how, why, what, and when' of cosmetic claims, highlighting the need for a comprehensive guide. Having worked with many clients, I noticed a common struggle with the EUs 2013 claims regulation. Brands faced challenges in providing evidence and understanding the regulations, needing more than just basic advice. Thats when the idea for my book was born. I launched the first edition in the fall of 2019. But as time went on, I realized there were new challenges emerging – especially with the explosion of misinformation on social media. So, with the encouragement of colleagues, I updated and rewrote the book in August of last year, adding more insights to reflect that shift and help businesses navigate this new landscape. Its currently available in English and French, and I’m working on the German and Spanish editions, which will be out soon. Its really exciting to see it reach a broader audience!

 

3.     How did you become a skincare scientist?

 

It all started by accident. After completing my PhD in plant biochemistry, I found myself in Paris, thanks to an opportunity with a visiting professor from the Pasteur Institute studying a skin disorder. While there, LVMH Dior invited me to collaborate on their research on the Capture project. Suddenly, I was thrust into the world of cosmetic science—a field I hadnt expected but quickly grew passionate about. Reflecting back, it feels like fate. I remember a biology class in school, where we discussed careers in chemistry and biology. I was intrigued by research in the field of fragrances, and also the Pasteur Institute. My teacher mocked me, saying only the intelligent” went there—well, I did, and thats where it all began.

 

4.    You write about the misinformation that is out there in regard to cosmetic company claims about their products. What types of things do they tend to fudge?

 

While EU law requires compliance with the six claims criteria (Legal, Truthful, Evidence, Honest, Fair, Informed Decision), many claims, especially the free-from claims can be tricky for brands, as they must not in any way denigrate ingredients that are legally permitted or demean brands that don’t use free-from claims. We often see free-from claims for ingredients which are not legally permitted, so the claim becomes a futile exercise, and some brands have been caught out by this. Another area is not having sufficient numbers of volunteers enrolled in a study be it clinical or consumer based. Extrapolating data from an ingredient suppliers data sheet is very common indeed, and is poor science and illogical if you think about it. Other examples are the not-tested-on-animals claim, which again in the EU makes no sense as animal testing has been banned for decades. Finally, those unapproved certification labels which are just a money-making exercise for some providers. Much of the fudging, at least in the EU, is down to ignorance and not doing the homework!

 

5.     What do consumers need to do to make sure they are using products that are safe?

 

When it comes to ensuring that the cosmetics youre using are safe, there are a few simple steps to follow. First, always check if the product is properly regulated by the relevant authorities, like the FDA in the USA or similar agencies elsewhere. These agencies ensure the products meet safety standards. Next, its super important to review the ingredient list. The most reliable and factual resource I can recommend is COSMILE.  If you have any allergies or sensitivities, be cautious and  get checked out by your doctor. Avoid using products recommended by friends or social media, as what might be right for their dry skin may not be right for yours! I also recommend doing a little research on the brand. Look at reviews and see what other consumers are saying. Its always a good idea to avoid products with outlandish claims that sound too good to be true – they often arent backed by science.

Finally, stay informed about any product recalls or safety alerts. Keeping up with industry news can help you avoid products that could pose a risk. Simple steps like these can really go a long way in making sure your beauty routine is not only effective but safe!

 

6.     Are there a lot of claims about cosmetic products being green and good for the environment that are fake?

 

Absolutely! Greenwashing has become a major issue across many industries, including fashion, cars, and of course, cosmetics, where misleading claims about sustainability and eco-friendliness are unfortunately all too common. Fortunately, both the EU and the UK have taken strong action to crack down on these deceptive practices, which includes ‘influencers’. Their consumer marketing authorities are actively enforcing regulations to ensure that brands can't make unsupported claims about being green” or sustainable” without proof. This has forced many ingredient suppliers and brands to become much more transparent, particularly when it comes to sourcing, traceability, and environmental impact. As a result, were seeing more companies trying to align their efforts with the UNs sustainability goals, which is a step in the right direction. While theres still a long way to go before the industry becomes fully sustainable, the increased pressure for accountability has definitely sparked positive changes. It's encouraging to see brands working to improve their environmental footprint and ensuring their claims are backed by real, verifiable actions.

 

7.     Do you blame influencers for helping to spread false cosmetic claims?

 

Influencers can certainly play a role in spreading misinformation about cosmetic products, but it's important to recognize that the responsibility doesn't fall entirely on them. Many influencers, especially those with large followings, are often promoting products for commercial gain or brand partnerships. In many cases, they may not have the expertise to critically evaluate the products they endorse or fully understand the science behind them. This can lead to exaggerated or misleading claims about effectiveness and safety, which then starts the snowball rolling. However, the responsibility also lies with brands and companies that may encourage influencers to make bold claims without proper evidence. This would be illegal in the EU. Many influencers are not always given the proper guidance on how to communicate the truth about the products they promote. While influencers can contribute to misinformation, it's a larger issue of accountability across the entire industry, including brands, regulatory bodies, and all media including social media platforms, which all need to be more proactive in ensuring truthful marketing.

 

8.     What level of transparency exists in todays landscape of cosmetic advertising?

 

In the USA, cosmetic advertising is mainly regulated by the Federal Trade Commission (FTC), which ensures that ads are truthful and not misleading. The FTC requires that any claims made in ads—such as effectiveness or safety—be backed by solid evidence. However, the FDA oversees the safety and labeling of cosmetics, not the advertising claims themselves. In contrast, the UK and EU have much stricter regulations. In these regions, advertising claims must be substantiated with scientific and/or substantial consumer proof, and there are robust rules against misleading marketing laid down by the advertising standards authorities. Overall, the UK/EU seems to offers stronger consumer protection in terms of transparency and truthful advertising, while the USA has more flexibility, which can sometimes lead to misleading claims slipping through the cracks, and you see many adverts in the USA with the opaque statement ‘these statements have not been evaluated by the Food and Drug Administration’. This would never be permitted here in the UK/EU. In the UK complaints about advertising are posted online by the ASA and serve as an education tool for both the consumer as well as industry. Most EU countries have a similar format.

Biochemist Callaghan delves into the history of the cosmetics business-and cosmetic claims development-in hopes of demystifying an industry where, she writes, "selling hope" reigns supreme. Aimed at consumers, influencers, and journalists, Callaghan's informative guide delivers a glimpse into the inner workings of the business, covering modern technology's impact on cosmetic product development, ethical beauty standards, the research that goes into substantiating cosmetic claims, and more. Callaghan also confronts "fundamental questions about our relationship with cosmetics and the pursuit of beauty," with a heavy emphasis on the science driving the industry. 

“Callaghan's guide is enlightening, as she addresses how to differentiate between fact and fiction and "make informed decisions about... skincare regimen[s]." Her goal with this updated edition is to "[bridge] the gap between the cosmetic Counter and the laboratory, and she accomplishes that objective with flying colors. 

“From a breakdown of the different types of cosmetic claims-ranging from lifestyle to ingredient to sensory-to instruction on the anatomy of skin, Callaghan's easy-to-read text covers all the bases, teaching consumers the ins and outs of an admittedly complex business. She consistently revisits safe and ethical product development, asserting that "product development pathways have to be turned on their head and re-drawn," and is a staunch advocate for rigorous scientific standards, arguing that "time and money to build a body of evidence has to be a first priority"
