Irritated Skin

Irritation Research

Irritation from the application of alpha-hydroxy acids or other acid formulations may result in the removal of several layers of the skin. Depending on the strength of the product and the frequency of application, the removal of epidermal layers can compromise the barrier function of the skin. NOVA instrumentation may be used to track the effect, allowing researchers to monitor the barrier functionality. Because the barrier function is a naturally resistive element of the skin, when it is compromised, impedance readings will increase.

Users can track the effectiveness of their products as it is related to the breakdown of the barrier function. They can use the instrument to measure the skin impedance to a certain level of compromise, as well as to track skin regeneration. For additional information, please contact NOVA at
