Sensitive skin syndrome is defined as the presence of burning, itching or any other unpleasant sensation on the skin, due to physical, chemical or psychological factors. It is frequently a self-diagnosed condition, and there are no accurate tests to recognize or quantify it because of the individual variations in perception and intensity of the related symptoms. The most accepted physiopathogenic theory is the presence of an altered barrier function of epidermis. Also, changes in the pH of the stratum corneum have been found to induce skin sensitivity through the activation of the transient potential receptor vanilloid (TRPV) neuronal receptors.
