Lack of effective treatment
When dry skin is not treated quickly, the severity of the dryness can increase, and the moisture network in the deeper layers can be disrupted. In these situations, a moisturiser that addresses this problem is necessary.
When protecting dry skin from sun exposure, it is important that the sunscreen also restores missing moisturising factors, in addition to an appropriate Sun Protection Factor (SPF). It is also important that the sunscreen, and any other skin care products used on dry skin, do not contain irritating perfumes and colourants, as dry skin, especially dry facial skin, is more prone to irritation than normal skin.
Some occupations require working in conditions that may increase the risk of dry skin. Typically these are occupations that require exposure to the causes of dry skin, such as working in hot or cold conditions (farmer/fisherman), or frequent use of detergents (doctor/nurse/hairdresser), or exposure to chemicals (mechanic/cleaner).
The skin receives its moisture via the body, and is therefore dependent on the body’s water balance. When dehydrated, the body reduces the supply of moisture to the skin which slows down the natural flow of water through the skin, which can contribute to dry skin. Elderly people are prone to dehydration as the sensation of thirst diminishes with age.
Cigarettes contain many toxins, including nicotine, which may reduce the blood flow. This results in a decreased metabolic rate within the skin. This means the skin may age prematurely and dry out.
