Sensitive skin has different profiles. Intolerant, red, dry or dehydrated skin can in fact be sensitive. They have one thing in common: the skin is hyper-reactive to certain factors.
The different symptoms of sensitive skin
Sensitive skin is not necessarily allergenic skin. It is a type of skin that is naturally vulnerable to outside attacks, which it has an extreme reaction to. This hyper-reactivity is directly linked to the excitability of the skin's nerve endings.According to each profile, sensitive skin can therefore manifest itself through different types of reactivity, which may accumulate: prickling, tightness, itchiness, heat discomfort and/or burning sensations, sometimes combined with redness.
The 3 origins of skin reactivity
Skin reactivity can have several causes. It can be:
- environmental: heat, cold, wind, sun or even sudden changes in temperature and atmospheric pollution can lead to prickling, burning sensations, redness or heat discomfort.
- contact: the application of a product that contains a poorly tolerated ingredient, the skin’s contact with very hard water or certain fabrics can cause feelings of discomfort: itching, prickling, tightness or redness.
- vascular: the walls of the blood vessels are weakened under the influence of certain external factors, like changes in temperature or internal factors, like eating spices or drinking alcohol. The appearance of flushes, redness and heat discomfort can be revealing signs.
