An article published in Pediatric Dermatology discussed that there have been continuing efforts to understand the effects of baby skin care routines and products on healthy development of baby skin—to determine the best infant skin care practices. However, the pediatric and dermatologic communities have not reached consensus on what constitutes an appropriate cleansing practice.

The authors stated that accumulated knowledge has promoted evidence-based clinical practices and, therefore, may help in improving clinical outcomes, although these guidelines primarily cover the care of preterm newborns and the treatment of those with other health problems. But, high-level, long-term clinical evidence of the effective and safe cleansing of healthy, full-term newborns and infants is scarce.

This article was based on a review that presented a comprehensive analysis of the scientific literature on baby skin development, cleansing practices and related products for healthy newborns and babies, since 1970. The evidence drawn from the reviewed literature suggest that bathing immersed in water seems superior to washing alone. Bathing or washing with synthetic detergents or mild liquid baby cleansers seems comparable with or even superior to water alone.

The review summarized that larger randomized clinical trials (RCTs) with age-defined cohorts of babies, as well as more-defined parameters are required to identify optimal practices and products for skin cleansing of healthy infants. These parameters may include standardized skin function parameters – such as transepidermal water loss, stratum corneum hydration, skin surface pH and sebum production. Clinical skin scores such as the Neonatal Skin Condition Score may be employed as outcome measures.
