“…67 Several explanations are valid including a T-helper cell 2 bias from hapten exposure in emollients and facilitated passage of food allergens across the skin-barrier following application. [68][69][70] Maintaining an intact skin-barrier and preventing onset of AD, especially early-onset AD, could possibly reduce the risk of FS, FA and CPFA.…”

Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by intense itch, dry skin and recurrent eczematous lesions. 1 Food allergy (FA) is triggered by exposure to a food antigen, and can manifest as urticaria, angioedema, gastrointestinal symptoms, respiratory problems and anaphylaxis. 2 In patients with co-occurring AD, eczema may worsen in hours to days after food exposure, while reduced exposure, or complete exclusion of food allergens in infancy, may improve or completely prevent AD. [3][4][5] It was traditionally assumed that primary sensitization to food allergens mainly occur as a result of allergen exposure in the gut, but it is now recognized that food sensitization (FS) can develop following primary allergen exposure on the skin. [6][7][8] Individuals with FS and FA often have skin-barrier impairment, even without co-occurring AD, 9-11 but AD seems to increase risk of developing FS and FA in a severity dependent manner due to significant skin-barrier impairment. [12][13][14][15][16][17][18][19] The skin may be impaired due to multiple factors such as reduction in chain length of essential lipids including ceramides, but also due to reductions of crucial skin barrier

“…In fact, natural oils have been used as penetration enhancers in the transdermal delivery of active pharmaceutical ingredients [77][78][79][80]. More than likely, the triglycerides in oils that are applied to the skin will be hydrolyzed by resident lipases resulting in the formation of free fatty acids, which can disrupt the ordered structure of lipid lamellae in the stratum corneum [81]. In general, the paradoxical effect produced by some oils is thought to be more prevalent in patients suffering from atopic dermatitis and other skin conditions.…”

The term natural oil refers to a fixed (non‐volatile) oil of animal or plant origin. These types of oils – in contrast to essential (volatile) oils, which are obtained by steam distillation methods of plant matter – are typically obtained from plant seeds and nuts by a mechanical pressing technique or solvent extraction. The natural movement in cosmetics of the 21st century has led to renewed interest in formulating skin care products with botanical ingredients. In this article, we discuss the benefits and caveats of natural oil treatments as moisturizing agents (as occlusives and emollients) as well as their utility in wound healing and treatment of skin diseases. We also address the paradoxical behaviour of natural oils in relation to barrier function and highlight the current state of our knowledge with respect to the use of natural oils in neonatal skin care. Finally, we provide a comparison of natural oils to conventional petroleum‐based oils.
