One of the most uncomfortable feeling is dry and dehydrated skin. The face will feel tight and painful due to peeling and flaking in the skin. Coupled with age, climate change, lack of sleep, or excessive fatigue, the skin can become even drier. To prevent dry skin, it is important to care for the epidermis. The epidermis includes the stratum corneum which is responsible for secreting natural oils to protect the skin. Typically, the stratum corneum’s moisture content is approximately 10%. When the skin’s moisture content is below 10%, the skin becomes dull and fine lines are formed.
