Redness and sensitivity of the skin are signs of a weakened skin barrier. Reactive skin reacts easily to external aggressions such as cold, heat, cosmetic products or pollution. These irritations manifest themselves through redness, itching and sometimes a burning sensation. To soothe and protect this type of skin, it is essential to use gentle care, without perfume or alcohol, rich in soothing ingredients. Good hydration is also crucial to strengthen the skin barrier and limit irritation.
