Very few skins are truly ‘sensitive’. Mostly, we speak about ‘sensitized’ skin, i.e. the skin appears sensitive because of what we have done to it, or what we may have omitted to do.
Dehydration of the skin will lead to micro-injuries, leading to inflammation and to sensitivity. The application of aggressive ingredients will cause the formation of inflammatory molecules, leaving the skin red and sensitive. Any action that interferes with or weakens/damages the skin’s natural protection is likely to lead to sensitivity and to redness. In fact, diffused redness is now a very common condition.
