Hydrolipid barrier– hydrolipid layer– protective barrier of the skin.
The hydrolipid layer is a mixture of sebum, sweat, lipids:
secretions of the sebaceous glands- sebum,
derived from sweat glands- water/ sweat,
produced in the metabolic processes of keratinocytes, i.e. cells responsible for the production of keratin- lipids (ceramides, sterols- cholesterol and its esters, free fatty acids, hydrocarbons).
The skin’s protective barrier performs the following functions:
protects the skin from various external factors: bacteria, fungi, toxins;
protects against negative environmental factors;
prevents the evaporation of water from the epidermis (protects against dryness, dehydration and roughness);
maintains the correct slightly acidic pH of the skin- thus enabling the growth of beneficial microorganisms (microbiome) on the skin, and limiting the development of pathogenic microorganisms; responsible for the processes of absorption and penetration of various substances into the skin.
The natural protective barrier can be weakened by:
too frequent exfoliation, strong cleansing, improper care; unfavorable weather conditions;
skin exposure to UV radiation;
being in a dry air environment; chronic dermatological diseases (e.g. atopic dermatitis);
too high a concentration of the new active ingredient and dermatological treatment;
lack of EFAs in the diet- essential unsaturated fatty acids- omega 3 and 6;
contact with detergents and solvents, mechanical injuries.
Symptoms of a damaged hydrolipid layer:
dryness, roughness, dehydration;
feeling of tightness, burning and itching;
irritation, redness and damage to the skin;
excessive sebum production;
the occurrence of inflammation;
hypersensitivity;
unhealthy gray or sallow skin tone.
