There are several causes of dehydrated skin. In most cases, dehydrated skin has a weakened barrier that allows too much moisture to evaporate. Environmental factors such as air conditioning, artificial heat, dry climates with low humidity, hot showers, and harsh skincare products can contribute to dehydrated skin. Lifestyle can play a role as well, since dehydrated skin can result from drinking too little water, lack of sleep, alcohol consumption, and more.

Dehydrated skin and dry skin have similar symptoms, but have different underlying factors. Dehydrated skin is characterized by a lack of hydration, while dry skin does not produce enough of its natural oils (sebum). Dry skin is a naturally occurring type of skin (as opposed to oily or combination skin) while dehydrated skin may be considered a temporary condition. Anyone can experience dehydrated skin, whether their skin type is normal, dry, oily, or combination.<sup>1

To improve dehydrated skin, in addition to drinking water, it is important to use skincare products and ingredients that provide the skin with extra hydration. Serums and daily moisturizers that contain hyaluronic acid or glycerin are effective for all types of dehydrated skin since these ingredients are known to help replenish moisture. Ceramides, cholesterol, and fatty acids, found in Triple Lipid Restore 2:4:2, are also beneficial ingredients for dehydrated skin since supplementing the skin with these naturally occurring lipids helps to reinforce the skin barrier so it can better retain moisture.
