To the Editor, Emollient and moisturizer preparations are recommended to improve skin barrier properties and are believed to halt the progression of the atopic march when applied from the first weeks of life in high-risk children.Such products comprise various types of substances, mainly humectants, oils, physiological lipids, preservatives, and different additives.Humectants such as glycerin or urea and oils such as paraffin, petroleum, ceramides, fatty acids, and cholesterol are essential ingredients in restoring the skin barrier.As recently demonstrated by Sindher et al., 1 there is an enormous difference in the impacts of different types of cream on atopic skin, and lipid-rich products are more efficient in improvement of skin barrier function comparing to paraffine-based.
