Skin barrier breakdown is a frequent condition and clinically presents as compromised skin [a patch of eczema, scaly and rough dry skin texture, skin sensitivity and redness] or a wound.
The skin acts as a barrier between internal and external environments protecting the body from mechanical damage, external substances, pathogens and irradiation. Changes associated with ageing and the accumulation of exogenous damage can alter skin function affecting skin health and appearance.
In order to be effective, nutritional supplementation should reinforce the skin barrier function to withstand these structural and functional changes.
Having reviewed the evidence, it seems to suggest that oral GLA [γ–Linolenic acid] supplements can improve skin barrier function.
- A 6% to 31% improvement in skin barrier was reported, which is in line with clinical improvements observed in the elderly; dry and sensitive skin; skin texture; itching; and perceived appearance.
- The studies that observed no changes in skin barrier though reported other benefits induced by supplementation, e.g., clinical improvement of dry skin texture and increased collagen deposition.
- However, body weight [BMI] and health status [pro-inflammatory markers in plasma] as well as seasonal changes can impact on the efficacy of the supplement.
OMEGA 3 – fish oils and safflower oil do not seem to have the same benefit.
