14. Dry Skin!
Dry skin is also called Xerosis, it’s a common skin condition that occurs at all ages. Although normally it is not a serious issue, but many times it is difficult to handle.
Dry skin normally appears dehydrated, peeled, irritated and inflamed. It feels rough, scaly, sometimes painful and itchy. Severe conditions may be characterised by intense redness and itchiness. Such dry skin shows tendency to crack, causing deep fishers that may bleed indicating extremely dry skin.
The skin actually represents the barrier against the environment, it is made up of three layers:
a. Hypodermis: It is the deepest layer of the skin and is mainly made up of Adipose tissue, with blood and lymphatic vessels and nerves.
b. Dermis: Made up of the connective tissue, which contains collagen as well as elastin fibres, Blood vessels, sebaceous glands, Hair follicles and Sweat glands.
c. Epidermis: the outermost layer of the skin. It is made up of Keratinocytes. The characteristic features of the epidermis include: Keratinocytes in the stratum corneum, contain an insoluble structure composed of several proteins. The cytoplasm is filled with keratin filaments and nuclear dissolution.
In Epidermis the keratinized cells are embedded in the lipid layers which are made up of cholesterol, fatty acids and ceramides.
Stratum corneum provides hydration and particularly the lipids in the stratum corneum plays an important role against evaporation and helps holding water.
What all is there along with the fats and dead cells in the stratum corneum? It contains the secretions of the sweat glands. It also contains the Natural moisturizing factors. These natural moisturizing factors contains Amino acids, Sugars, Lactic acid and urea.
When all these things are exciting, the question is why do skin turn dry?
The most simple causes of dryness include:
1. Destroying the stratum corneum lipids using harsh soap, itchy clothing, long and hot showers and baths.
2. Exposure to hot or cold weather, where the humidity is low. Dryness of skin often worsens in the winter, where several factors contribute to skin dryness, and in summer, constant exposure to air conditioning may produce similar effects.
3. Several drugs like diuretics or topical or systemic retinoids may temporarily cause dry skin.
4. In elderly patients, metabolic rate changes, and as the liquid intake reduces, it leads to indirect dryness of the skin.
5. Hormonal imbalances that occur in menopause, hypothyroidism and hyperthyroidism can also lead to severe skin dryness.
