Dry skin is the result of insufficient production of fat by the sebaceous glands in the skin and a dysfunction of water regulation. The causes can be multiple, for example:

  • Hereditary predisposition,
  • Age,
  • Insufficient weight,
  • Dry air heating, air conditioning,
  • Humidity or air temperature,
  • Soaps and shower gels,
  • Cleaning lotions,
  • perfumes,
  • Drugs (such as diuretics),
  • Means of hormonal contraception,
  • Radiation.

Insufficient nutrition or malnutrition, as well as the consumption of alcohol and tobacco can also cause dry skin.

5 foods to favor and avoid to have a beautiful skin

Good looks, reduction of pimples and signs of age, begins in the kitchen. What foods to favor and avoid to have a beautiful skin?

Poorly vascularized body areas that are largely free of sebaceous glands (eg, lower legs) are at particular risk of developing dry skin.

Especially in winter, many people suffer from dry skin. The cold air and the low humidity of the outside air associated with the hot and dry air of the heating inside, put the skin to the test and dry it.

All about skin health

Acne, psoriasis and herpes, shingles, urticaria and skin cancer ... all you need to know about skin diseases!

The skin tends to be drier with age, which can be explained by different causes. The following mechanisms promote, among other things, the appearance of dry skin at age:

  • The production of sebum naturally decreases with age.
  • The epidermis loses its ability to retain moisture.
  • The sweat glands secrete less sweat.

Besides these physiological reasons, different diseases can cause dry skin, for example :

  • atopic dermatitis,
  • psoriasis,
  • eczema,
  • diabetes,
  • hypothyroidism (insufficient production of hormones by the thyroid),
  • certain intestinal diseases (for example, Crohn's disease, ulcerative colitis and inflammation of the small intestine),
  • gastritis,
  • Zollinger-Ellison syndrome (characterized by the presence of gastrointestinal ulcers),
  • certain allergies (eg, food or laundry products), etc.
