Signs:
- Uneven dull skin surface, peeling.
- Redness and irritation in response to heat or cold.
- Tightness may be felt after washing
- Visible pores.
Dry skin loses elasticity, its barrier functions are reduced.
Causes:
- reduced activity of the sebaceous glands,
- deficiency of moisture and epidermal lipids,
- accelerated renewal of the epidermis, which leads to peeling.
All this can occur due to genetic characteristics or age-related changes, as well as under the influence of heat or frost, aggressive cosmetics.
Dietary factors: lack of healthy fats in the diet, strict diets or fasts, radical veganism.
Solution:
- hydration of the epidermis,
- restoration of the lipid barrier with valuable natural lipids,
- cosmetics should not damage the protective mantle, which causes moisture loss, overdrying and irritation of the skin.
Most often, cosmetic products for dry skin include such ingredients as:
- moisturizers - substances whose molecules bind water molecules well: plant polysaccharides of aloe gel, algae extracts (Alaria esculenta, Pelvetia canaliculata etc), glycerin, urea, betaine.
- nutritive compounds which can repair skin barrier and protect skin from water loss: avocado oil, cocoa butter, shea butter, cupuacu oil, argan oil, rosehip seed oil, lanolin, squalane.
