The cosmetics industry requires companies to continuously develop new products that satisfy consumers. Recently, artificial intelligence technology (AI) has come to the fore and has already been successfully integrated into major industries. AI tools allows companies to understand customer preferences through virtual try-on and facial analysis, enabling the creation of personalised cosmetic products and recommendations, facilitating formulation development, ingredient sourcing, improved marketing strategies and better user experience. ChatGPT and Microsoft Copilot are used among consumers as counselling aids and provide quick answers to various questions. Both are language models that are capable of complex thinking, integration of ideas and learning. In the context of the thesis, we evaluated their answers to questions that were posed in a way that required a specific answer in relation to regulatory and innovative questions, where they had to provide a reasoned synthesis of knowledge in the field of formulation, cosmetically active ingredients and the use of cosmetic products. Our results show that the models successfully answered questions related to changes in formulation, suggestions for specific skin problems and mechanisms of ingredients, as they were able to draw their answers from a variety of sources, while the biggest drawbacks were correct citation of articles, difficulty in keeping up with regulatory changes and inadequate terminology. In the second part of the thesis, we reviewed 50 articles and news from the peer-reviewed literature that met the selected criteria and analysed them according to the type of article, year of publication, use of AI, country and employment of the authors, and positive/negative arguments for the use of AI. The results showed that review articles and original research articles are the most frequent; that the literature on AI in the cosmetics industry is growing; that AI is mainly used in facial, hair, skin analyses, personalised recommendations and as assistance with formulation; that the majority of authors are from India and the USA and are employed by companies already using AI; and that the main positive argument is that AI helps companies to increase consumer satisfaction. From the results of thesis, we can conclude that ChatGPT and Copilot are good tools, but they are problematic in terms of spreading unverified information and misquoting articles, which can result in plagiarism, misunderstanding of context and reduced credibility, so caution and critical assessment of information is needed. AI is being successfully integrated into the cosmetics industry and we anticipate that its use will continue to grow.
