Sensitivity depends on the immune system that is activated in the presence of harmful substances: the pollution rate is always higher, especially in cities, as a result the skin has become more reactive (that’s why sensitive skin is also called hyper-reactive).
When the function of the hydrolipid barrier is impaired, the skin is vulnerable and reacts to external stimuli in an exaggerated way: it irritates and reddens easily, appears dry, thin and without brightness.
It is good that the immune system is activated: the skin is like the wall of a castle that does not pass external "enemies".
Sensitive skin is characterized by the following signs of discomfort:
Sensitive skin can appear anywhere on face and body.
1. THE SUN
The sun UV rays stimulate the formation of free radicals that, causing oxidative stress, can damage the health of the skin, weakening its protective mechanisms.
2. THE TEMPERATURE
The wind, cold and low temperatures cause our body to defend itself, conveying a greater quantity of blood to the internal organs and decreasing the spraying of its outer covering. The skin reacts to this phenomenon by producing less collagen, thinning and slowing down the elimination of free radicals . Their greater concentration is responsible for the dull complexion that our skin tends to assume during the winter.
The most important consequence of the reduction of the nourishment that the skin receives from the blood during the cold season is the decrease of the synthesis of lipids normally present to skin level, the function of which is to limit the loss of water through the stratum corneum.
Even heating and air conditioning tend to cause dehydration of the skin or more commonly the feeling of "skin pulling".
Pollutants (cigarette smoke, smog, fine dust) can attach to the skin, clogging pores and thus reducing the ability of the skin to breathe
4. WATER HARDNESS
A high content of calcium and magnesium in the water can disturb the delicate balance of the pH of the skin, increasing the level of sensitivity and ease to redness.
5.AGGRESSIVE CLEANING AGENTS
Sensitive skin also shows a greater predisposition to premature skin aging, which further accentuates the dryness and the production of free radicals with irritant and inflammatory action.
The frequent use of cleaning agents and cosmetic detergents with surfactants that attack the hydrolipid layer of the skin by altering it is often a cause of dehydration and redness. Water, especially if too hot, further depletes the hydro-lipid film of the skin causing that annoying "skin pulling" sensation
A proper cosmetic routine is very usefult: the daily use of detergents and moisturizing and emollients creams normalizes and strengthens the skin barrier that is essential to ensure proper hydration of the skin.
Sensitive skin needs specific care to effectively and gently combat imperfections
choose a few products formulated with a limited number of ingredients of natural origin and proven effectiveness, in order to limit the risk of irritation and able to provide immediate relief to hot skin.
