Sensitive skin

In cosmetology "sensitive skin" is meant definition the skin type inclined to the increased irritability and unpredictable reaction in response to daily external and internal agents. Sensitive skin can react the external manifestations to exhaustion, a stress, a sleep debt, cold wind, water and decorative cosmetics. It is inclined to tightening, reddening, a peeling, emergence of the small itching rashes.

From hypersensibility of skin women with a fair or red hair, transparent thin skin, blue, gray or green eyes most often suffer. Such skin has poorly expressed horn layer, it is not enough pigment, her sebaceous glands excrete not enough fat. All this does sensitive skin especially vulnerable for external irritants and internal stresses.

Sensitivity of skin to various irritants (cosmetics, climatic conditions, psychological loadings) often confuse to allergic or skin diseases, for example, a rozatse or seboreyny dermatitis. However, if reactivity of skin is shown suddenly, without the thorough reasons, then, most likely, it is about sensitive skin.

Types of sensitivity of skin

The reasons causing hypersensibility of skin formed the basis of classification of its main types.

  1. Suddenly arising, proceeding some time, and also sharply passing condition of hypersensitivity of skin. It is caused by a jet state which tests an organism after psychological injuries, serious illnesses, drug intake.
  2. Sensitivity of skin arises against the background of pathology of internals (more often than digestive tract), infectious, allergic, skin or endocrine diseases, violations from immune system. Decrease in reactivity of skin occurs after elimination of the main disease.
  3. Hypersensibility of skin is caused by the wrong leaving, use of incorrectly picked up cosmetics or cosmetics of poor quality.
  4. Sensitivity of skin is caused by its congenital features – dryness, a subtlety, weakness, a lack of protective pigmentation. Such skin - destiny of blond and red-haired women with gray-blue or green color of eyes. Practically any external irritants (a heat or cold, water or the sun, wind or dust etc.) can provoke its reaction. This type of sensitive skin needs careful leaving by means of nutritious and protective creams.

Whims of sensitive skin

The top, horn layer of epidermis on the function is the main barrier on the way of penetration into skin of harmful agents. Hypersensibility of skin is caused by thinning of a horn layer of epidermis and, as a result, decrease in its barrier function. Insufficient protection against adverse external effects leads to free penetration into skin of various external irritants. Protective function of skin is provided by also immune cells of skin and normal functioning of sweat and sebaceous glands.

Sensitivity of skin is not always caused by congenital features of a structure. Sometimes, seeking to improve the appearance, we, without suspecting that, we subject skin to unfairly cruel influence. The peeling srubs, chemical peelings, masks and creams with acids and retinoida, experiments at cosmetics choice negatively influence a condition of a horn layer and even more thin skin. And during one fine instant instead of the expected effect on skin there are a reddening and irritation. So, unconsciously ourselves can turn the skin into sensitive.

The most vulnerable are face zones with anatomic thin structure of skin or with the lowered lipidic barrier. It is area of a nasolabial triangle and a zone around eyes – as a rule, here irritations of skin most often appear.

Internal mechanisms of protection of skin

Skin barrier

The regulator of loss of moisture through skin is the horn layer of epidermis. It keeps necessary amount of moisture, preventing excessive dryness of skin. Dry skin involves decrease in barrier function and serves as the contributing factor to its sensitivity. It is extremely subject to influence of adverse external irritants (injuries, chemicals, infectious agents) and reacts to them hypersensibility.

Skin fat

Other important protective factor is the skin fat emitted by sebaceous glands. The lipidic film which is formed on the surface of skin softens and protects skin from damages and penetration of an infection. The insufficient office of skin fat also leads to decrease in a protective barrier and dryness of skin. At the same time, and its excessive allocation increases sensitivity of skin since separate components of skin fat (fatty acids, ) can cause irritation.

Level of acidity of skin

Optimum index of acid-base balance of skin is pH = 5,5. Such level of acidity is supported thanks to normal function of sweat glands. Besides, sweat carries out a protective role - neutralizes mechanical, chemical, microbic pollution of skin. Violation of the pH index in the sour party causes a loosening of epidermis and increase in sensitivity of skin.

Frequent side effect of retinoid are dryness, a peeling and reddening of skin, and their prolonged use causes special sensitivity of skin. Also salicylic acid and alpha hydroxyacids (ANA) belong to the substances increasing sensitivity of skin.

Some ingredients of cosmetics of a biological and synthetic origin cause an allergization of integuments and the phenomenon of contact dermatitis. It, in turn, also conducts the increased skin sensitivity. Among vegetable components most often the phenomena of allergic contact dermatitis cause extracts of arnica, rosemary, a calendula, santalaceous oil.
