Sensitive skins are those that react in a different way to normal skin, reddening easily and experiencing sensations of discomfort, tightness and even alterations such as redness, itching, flaking or pustules.
Any skin type (oily, dry or combination) can be sensitive, although some are more prone than others. Those most likely to be sensitive are white, thin and dry.
These alterations are caused by a deficiency in the skin barrier, which is weak and permeable, allowing external agents to penetrate easily and causing dehydration. In addition, sensitive skin can also be characterized by an unbalanced microbiome.
