PG - 2319-2326 LID - 10.1111/jdv.15785 [doi] AB - BACKGROUND/OBJECTIVES: Paediatric skin, considered sensitive, and infant skin, more susceptible to percutaneous toxicity, require specially formulated cosmetic products. As recently shown, early use of emollients in infants "at risk" of developing atopic dermatitis has shown controversial results in reducing the incidence of atopic dermatitis. Development of dermo-cosmetic products for this specific population should especially ensure tolerance and safety. In absence of good clinical practice guideline, we propose here a stepwise approach for the development of paediatric cosmetic skincare products. METHODS: Our stepwise methodology for cosmetics aimed at paediatrics, starts with in vitro assessment of product's ingredients safety, followed by preclinical and clinical evaluations of the final product, including sequentially: (1) Repeated Open Application Test (ROAT), (2) Human Repeated Insult Patch Test (HRIPT), (3) In-use dermatological and ophthalmological tolerance studies (sequentially in 3a: healthy adults, 3b: healthy paediatric subjects and finally 3c: paediatric patients). We also describe the integrated cosmetovigilance-toxicological surveillance during the clinical development phase and postmarketing. RESULTS: As illustrated with one dermo-cosmetic product intended to be used as a preventative/maintenance treatment for atopic dermatitis in paediatric population, we show that using this stepwise methodology to test a product reduces potential risks of irritation and contact dermatitis in this sensitive population. CONCLUSION: Standardized ethical stepwise development approach is needed to ensure the commercialization of safe and well-tolerated dermo-cosmetics for paediatrics. The approach described here could potentially serve as guidance for evaluation of new paediatric cosmetic products. CI - (c) 2019 The Authors.
