Dry skin, or aipoid skin, generally refers to skin lacking oil, whereas dehydrated skin is characterised by a lack of moisture in the outermost layer of the epidermis.
Both dry and dehydrated skin is often irritated, inflamed and itchy, and it is generally worse in areas with relatively few sebaceous (oil) glands such as arms, legs and torso, as well as the cheeks and eye area. There is also a widespread misconception that dehydrated skin is the opposite of oily skin. Dehydrated refers to a lack of moisture(not a lack of oil), while oily refers to levels of sebum. While adequate sebum does help maintain water levels on skin, oily skin can be dehydrated. Dehydrated skin may lack water only in the outermost layers of the epidermis while maintaining normal levels in deeper layers.
Other symptoms of dry skin can include a feeling of tightness or tautness, especially after showering, bathing or swimming, skin can that feels and looks rough rather than smooth, slight to severe flaking or scaling, fine lines, cracks that can sometimes bleed and severe redness.

The top five causes of dry/dehydrated skin are

Intrinsic ageing
Intrinsic ageing also known as healthy ageing, is the normal process of physical change over time that is more about genetics than lifestyle. (Lifestyle induced ageing is known as premature ageing.) The process begins in our mid-20s, but unlike premature ageing induced by external factors, does not begin to show on our faces until decades later.
Dry, dehydrated skin is common in older skin, since the activity of the sebaceous glands tends to decrease with age, and the skins natural dehydrators decline over the years. ageing may also cause blood flow to the skin to decrease, causing drop in sebum production.

Over-Cleansing
The loss of existing sebum is commonly caused by excessive bathing or showering, scrubbing, or the harsh use of soaps that dissolve the protective layer of sebum. Often dry hands are suffered by those working in the food preparation and nursing as they must frequently wash to rid their hands of potential germs.

Cold Weather and Low Humidity
Cold winds and low temperatures can try out skin, depriving it of balanced levels of sebum (oil) that keep skin lubricated . Without these oils, skin becomes dry, and is more prone to premature ageing because of a lack or protective oils .
This includes forced air heating as well. Warm, dry air acts like a giant sponge, soaking up moisture from everything it touches.

The Sun
Although many people complain of dryness through the winter, others experience dry skin in the summer. Prolonged exposure to the sun causes water to evaporate from the skin, which is why skin that is recently tanned or burned often requires more moisturisation than areas that were not exposed. Summer activities, such as swimming, can also contribute to dryness, as chlorine in pools and salt in ocean water causes skin irritation.

Lifestyle
Nutritionists say that those surviving on a litany of diet sodas and fat free fad items are missing out on vital, skin friendly essential fatty acids (EFA) and fat soluble vitamins. (Don't forget that fat-free food items often substitute sugar with artificial sweeteners that can cause skin sensitivity.)
An EFA deficiency can result in skin problems such as chronic itching, dryness, scaling and thinning.
Smoking can also have a drying effect on skin, as smoking inhibits the body's ability to provide oxygen and nutrients to the skin. Excess intake of alcoholic beverages and certain medication (such as nasal decongestants) can also contribute to dry skin.

Over-Cleansing
The loss of existing sebum is commonly caused by excessive bathing or showering, scrubbing, or the harsh use of soaps that dissolve the protective layer of sebum. Often dry hands are suffered by those working in the food preparation and nursing as they must frequently wash to rid their hands of potential germs.

An effective treatment will include exfoliation to help prep the skin to receive nourishing ingredients, the use of emollients and hydrators to replenish skin, and vitamins to help smooth skin, stimulate collagen production and increase the skins natural protective barrier. It is imperative to recognise that the success of skin treatments will be heavily influenced by the regimen and the wearing of sunscreen for anytime the skin is exposed to daylight.
