Summary
Written by AI, not yet AICS's view · claude-haiku-4-5-20251001This is a literature review of the science behind infant skin physiology and the formulation of baby skincare products. It examines how infant skin differs from adult skin and identifies requirements for safe topical formulations. The review emphasizes the need for gentle, non-irritating ingredients that protect the developing skin barrier. While the topic touches on child health, the focus is on cosmetic product chemistry and ingredient safety rather than child well-being outcomes or interventions.
Key points
- Infant skin is physiologically distinct from adult skin with lower moisture levels and underdeveloped barriers
- Topical formulations for infants require thorough screening of ingredients
- Regulatory guidance emphasizes mild, non-irritating, and non-sensitizing ingredients
- The review examined 110 articles on infant skin physiology and cosmetic ingredient safety
- Ongoing research and regulatory harmonization are needed for safety of infant topical products
Limitations
This is a descriptive literature review focused on product formulation science and ingredient chemistry rather than evaluating health outcomes or interventions for children's well-being. It does not measure whether specific skincare practices or products actually improve child health or development.
Abstract
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.
