What Is Dry Skin?
Dry skin is caused by excessive or rapid loss of moisture from the skin. Several factors contribute to dry skin:
- Impaired barrier function of the stratum corneum (the outer layer of the skin) is perhaps the most significant cause of moisture loss from the skin
- Exposure to dry environments (i.e., those caused by air conditioning, arid environments or low humidity during the winter months) will leach out moisture from the skin
- Heredity may contribute to dry skin
- Environmental factors (air pollution, sun light, make-up)
- Certain dermatological conditions such as Eczema, Seborrheic Dermatitis (Dandruff of the face) and Psoriasis
- Normal aging of the skin reduces the barrier function
The Persistent Dry Skin Cycle
Dry skin may be an occasional problem for some, but for many it is much more. When the skin becomes dry, the epidermal layer loses its ability to retain moisture. Without continuous moisturization and correction, the skin cannot repair itself, leading to a vicious cycle of persistent dry skin.
