Guidelines for Infant Skin Care from Pediatric Dermatologists

Christina Boull, MD, a pediatric dermatologist at the University of Minnesota, shared her recommendations on newborn skin care during the American Academy of Pediatrics (AAP) 2026 National Conference & Exhibition. She emphasized that it is crucial for pediatricians to help parents navigate the crowded skin care market with practical advice about ingredients, cleansing, and moisturizing.

Newborn skin is particularly vulnerable due to its developing barrier, which can lead to greater moisture evaporation and increased susceptibility to irritants and bacteria. Boull analogized the infant skin barrier to a "leaky wall" and explained that products should be selected with this increased permeability in mind. She stated, "Moisture evaporates more easily through that skin layer...and irritating substances can cross over more easily."

Boull noted that the market’s promotion of natural or organic products can be misleading. Many marketed products may not be suitable for sensitive infant skin, as they often contain plant materials that could irritate. She advised families to use fragrance-free products and to avoid harsh cleansing agents, such as sodium lauryl sulfate, which can disrupt the skin barrier. Additionally, she cautioned against using lavender essential oil due to concerns about potential estrogenic effects in children.

Marketing terms like "hypoallergenic" may be comforting but do not guarantee a product's safety for newborns. Boull urged families to scrutinize ingredient lists instead. In her pediatric dermatology clinic, she utilizes an electronic health record that includes a list of gentle skin care products, which could serve as a resource for other pediatricians.

Regarding bathing frequency, Boull clarified that it is a misconception that frequent bathing is detrimental to newborn skin. She stated that bathing can be soothing and contribute to infant comfort and temperature regulation, allowing for a flexible approach depending on family needs. However, she stressed the importance of using appropriate cleansers. Traditional soaps may disrupt the skin's natural pH and barrier, so she recommended using gentle, soap-free synthetic detergents.

Moisturizing has an essential role in supporting the developing skin barrier, especially for infants with sensitive skin. Boull introduced the "soak and smear" method, where bathing is followed by moisturizer application to maintain hydration. She called for regular moisturizing, noting that emerging research suggests this practice may decrease eczema rates in young children.

Boull's guidelines advocate for a simplified approach to infant skin care, addressing common misconceptions and enabling pediatricians to offer targeted product recommendations, reassurance regarding bathing, and moisturizing instructions to protect newborn skin effectively.
