Abstract:
Because of the lack of objective signs, the phenomenon of sensitive skin is hard to document. The measurement of the skin pH variations in the nasolabial fold, and on the forearm, after a single application of lactic acid on a preselected sensitive skin population, versus a control one, is proposed as a useful test to detect this kind of population.
