Sun exposure
Excessive sun exposure may increase facial skin dryness. It is therefore important to choose a sunscreen that is formulated for dry skin, which contains moisturising ingredients in addition to an appropriate Sun Protection Factor (SPF).
It is also vital that the sunscreen, and any other skincare products used on dry skin, does not contain any irritating perfumes and colourants: dry skin, especially dry facial skin, is more prone to irritation than normal skin.
Occupational hazards
Certain situations or jobs involve exposure to conditions that may cause dry facial skin, e.g. outdoor sports, gardening, holidays in cold areas. By avoiding outdoor and occupational irritants and using adequate skin care products you can combat facial dryness caused by these factors.
Dehydration
The amount of moisture in the skin is related to the amount of water that the body can supply. When the body is dehydrated, therefore, it is unable to supply adequate amounts of water to the skin, leading to dry skin developing.
People who are prone to dehydration include the elderly, as the sensation of thirst declines with age, as well as manual labourers and those who exercise regularly.
Smoking
The toxins in cigarette smoke, including nicotine, may reduce the blood flow. This results in a slower metabolism within the skin, causing skin to dry out and age prematurely.
