Top three causes of dry, dehydrated skin
The Top Three Causes of Dry, Dehydrated Skin
Dry, or dehydrated?
• Dry skin, or allipoid skin, generally refers to skin that is lacking in oil.
• Dehydrated skin is characterised by lack of moisture in the Stratum Corneum.
Both dry and dehydrated skin can experience:
• Irritation, inflammation, itchiness and sensitivity.
• A feeling of tightness or tautness.
• A look or feel of roughness.
• Slight to severe flaking and scaling.
• Fine lines, severe redness and cracks that can sometimes bleed.
The top three causes of dry, dehydrated skin:
Intrinsic aging is the normal process of physical change over time that’s more about genetics than lifestyle. (Lifestyle-induced aging is known as premature or extrinsic aging.) Sebaceous gland activity tends to decrease with age, and the skin’s natural hydrators decline over the years. The skin’s ability to regenerate lipids comprising the protective lipid barrier layer of the Stratum Corneum also declines with age, as does blood flow to the skin, which may cause a drop in sebum production.
Prolonged exposure to the sun causes water to evaporate from skin, which is why sunburned skin requires more moisture than unexposed areas. Cold winds, air conditioning units, forced air heating and low temperatures can also dry out skin and contribute to premature aging.
The trend of fat-free diets can deprive our bodies of skin-friendly Essential Fatty Acids (EFAs). This deficiency can result in chronic itching, dryness, scaling, thinning and can lead to an imbalance in prostaglandins (chemical messengers that do many things, such as control inflammation).
