sensitive skin is inflammation caused by a hyper-reaction to an external source. Any part of the body can be affected by sensitivity but the face is the usual problem area.
You might also suffer from sensitive skin if you have inherited a thin stratum corneum barrier, or it has been compromised, this makes you more sensitive to factors that normal skin is protected from or does not react to.
Skin that is ‘sensitised’ a temporary state of sensitivity caused by external factors can also hyper-react to irritants, resulting in inflammation. Skin can become sensitised when external influences damage the skin’s barrier, or after chronic exposure to damaging conditions which wear down the skin’s natural protection. The good thing about sensitised skin is that if you remove the irritant and give the skin the right care, the skin’s protective barrier can be restored.
