Callaghan Consulting International now operates on a deliberately limited basis, focusing on selected projects where independent scientific judgement and experience can add particular value.
My work remains centred on cosmetic claims, the evidence behind them and the effective communication of that evidence.
Claims & Evidence: Claims should be credible, relevant and supported by evidence appropriate to the product and the message being communicated. I provide independent advice on claims development and substantiation, including reviewing existing evidence, identifying evidence gaps and troubleshooting when claims or supporting data have become problematic. This can be particularly useful when an independent scientific perspective is needed before committing to further studies or deciding how existing evidence can reasonably be used.
Study Strategy: Good studies begin with good questions. I advise on the scientific strategy behind clinical, instrumental and consumer studies intended to support cosmetic claims. This may include study concepts, protocols, endpoints, methodologies and the interpretation of results.
My role is increasingly advisory rather than day-to-day project management, helping clients determine what evidence they actually need and how best to obtain it.
Scientific Communication: Complex science is only useful if it can be communicated accurately and understood. I undertake selected scientific and technical writing projects, including interpreting and communicating scientific evidence to professional, technical and industry audiences. I also provide independent review when scientific material needs to be both technically robust and appropriate for its intended audience.
Advisory, Lectures & Workshops: I continue to contribute on a limited basis to conferences, workshops, webinars and educational programmes on cosmetic claims, substantiation and related areas of cosmetic science.
I am also available for selected advisory assignments where an experienced independent perspective can help clarify a scientific, claims or evidence-related question.
Working Together: I now accept a limited number of projects and generally favour focused assignments where my experience can contribute without requiring extensive ongoing project management.
If you have a particular question or project you would like to discuss, please feel free to get in touch.
