The Science Behind the Label: Evaluating Claims in Dermatologist‐Recommended Cosmetics

Background Cosmetic product labels are a key communication tool between the cosmetic industry, consumers, and healthcare professionals. However, the clarity, consistency, and scientific basis of product claims remain under debate. Objective This study aimed to map and critically analyze the claims on labels of antiaging, facial care, body care, and sun protection products recommended by dermatologists, evaluating their scientific foundation and potential influence on consumer perception. Methods An exploratory study was conducted based on 110 products from 13 leading cosmetic brands available in the Brazilian market. Data were collected between 2021 and 2022 from both primary and secondary packaging. Claims were categorized into five criteria: raw material origin (e.g., natural), galenic formulation, safety, efficacy, and absence of specific ingredients (e.g., alcohol, preservatives, mineral oils). Claims were examined using recognized methodologies for claim substantiation and relevant regulatory frameworks. Results While many claims align with scientific methods and regulations, several terms remain vague or lack contextualization. Phrases such as “natural origin,” “safe,” or “clinically tested” were often inconsistent and presented without clear methodological references. This lack of standardization may hinder consumer interpretation and limit healthcare professionals’ ability to assess product relevance. Conclusion The study underscores the need for clearer, standardized language in cosmetic claims. Transparent, scientifically grounded communication can support informed consumer decisions and enable healthcare professionals to make more evidence‐based product recommendations.
