Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Lipids, particularly in the form of topical emollients and certain oral supplements (such as essential fatty acids), have scientific backing for their use in supporting the treatment of dermatitis. The skin barrier in conditions like atopic dermatitis is often disrupted, leading to increased transepidermal water loss and vulnerability to irritants. Topical lipid-based formulations—containing ceramides, cholesterol, and free fatty acids—help restore the skin’s barrier function and reduce symptoms of dryness, irritation, and inflammation. Several randomized controlled trials and meta-analyses have shown that topical lipid-rich moisturizers can improve clinical outcomes in patients with dermatitis, especially atopic dermatitis.

Oral supplementation with certain lipids, notably omega-3 and omega-6 fatty acids (such as evening primrose oil and borage oil), has also been investigated. While some studies indicate modest benefits in symptom reduction, the evidence is less robust and more variable compared to topical application. Leading guidelines recommend regular use of emollients containing physiological lipids as a cornerstone of dermatitis management. However, not all lipid types or formulations are equally effective, and more research is needed to clarify the benefits of different lipid sources and delivery methods. In summary, there is moderate scientific evidence supporting the use of lipids—especially in topical formulations—for alleviating dermatitis symptoms and improving skin barrier function.
