Skin barrier breakdown and "compromised" skin are common in the autumn [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. OMEGA 6 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. Please read the scientific paper in detail.
Medical students are taught that half of the facts they learn are not true - we just don't know which half. Some of our most widely believed medical facts are based on almost no evidence at all. Is being slightly overweight (with BMI 25 - 30) healthier? Health weight range is not based on solid evidence (e.g. a significant study undertaken on many thousands of people or several such studies) with clearly defined basic categories i.e. BMI greater than 30 [Body mass Index; the ratio of body weight to the square of body height (kg/m2)]. Meta-analysis, is usually the holy grain of medical research, to provide the definitive answer to a scientific question. When the WHO (World Health Organisation) experts gathered to define obesity, BMI 30 has been chosen arbitrarily. Yet, obesity in middle age can reduce the risk of a person developing dementia later in life; to be overweight may well be healthier than to have normal weight. People who are considered overweight, with BMI 25 - 30, live longer. If methods of defining cut-off points in healthcare are largely arbitrary, it come as no surprise when the health definitions do not stand up to scrutiny.* In the ageing face, intuitively extra weight seems to add plumpness to the facial structures temporarily but research shows that thicker subcutaneous fat layer is
