Dry skin can be caused by many different factors. The key factors are the level of oil on the skin and the integrity of the skin’s barrier function. Both of these will determine the rate of Trans Epidermal Water Loss (TEWL) – the rate at which water evaporate through the skin.
Skin is dynamic and will react to its environment. If you apply products that are very high in oils that do not penetrate the skin, the skin will react by reducing the amount of sebum that it produces. This means that if you stop applying the cream, your skin will be dry for a few days while your skin starts to produce its own sebum again. It’s worth going through a few days of slightly dry skin to break your skin’s reliance on occlusive oils.
There are two types of dry skin – lipid dry and dehydrated. The two are often linked, but they are separated here for ease of diagnosis.
