Eucerin has identified three aspects to hypersensitive skin: a compromised skin barrier, hyper-responsive sensory fibres in the epidermis and redness, often caused by inflammation. As many of the symptoms are non-visible the sensations experienced by sufferers are subjective but many report feelings of stinging or burning. These sensations can be accompanied by dryness, redness and may develop into Couperose-prone skin or Rosacea.
