Introduction: Objective: The infant’s skin is physiologically and functionally distinct from adult skin, making it vulnerable to infections and disorders. Topical formulations developed for infants require thorough ingredient screening to protect their underdeveloped skin barriers. This review explores the anatomy and physiology of infant skin, highlighting the essential requirements for its care, and evaluates baby skincare products, emphasizing the need for gentle, non-irritating, and microbiome-friendly ingredients. Methods: A thorough literature review was performed using data cited in PubMed, Scopus, and Web of Science up to March, 2025. Keywords included "infant skin physiology," "neonatal dermatology," "topical formulations for infants," and "cosmetic ingredient safety." Articles relating to studies proving the safety of ingredients used in infant products and market trends were included. Overall, 110 articles were selected based on relevance, quality, and publication date. Results: The review highlights significant differences between infant and adult skin in moisture levels, the skin barrier, and enzyme levels. Infant and baby skincare formulations, such as creams, oils, powders, etc., must include ingredients that prioritize the integrity of the infant skin barrier. Regulatory guidance emphasizes the use of mild, non-irritating, and non-sensitizing ingredients. Discussion: The review integrates infant skin characteristics with formulation science and ingredient safety considerations, offering practical guidance for designing gentle, non-irritating, age-appropriate topical formulations. Conclusion:: The vulnerable characteristics of infant skin require vigilance in ingredient selection and formulation development. Ongoing research and regulatory harmonization are essential to ensure both efficacy and long-term safety of infant topical products.
