Comparison and correlation between stinging responses to lactic acid and bioengineering parameters.
Contact Dermatitis. 2007 Sep; 57(3):158-62.CD

Abstract

In evaluating the safety of a novel cosmetic product or a new chemical, it is important to assess susceptible population. One group of subjects is known to stingers who are more likely to experience sensory effects such as stinging and burning after contacting with cosmetics. The purpose of the study is to measure skin biophysical parameters noninvasively in stingers and non-stingers and to see their correlations with stinging responses. 298 women were evaluated by modified lactic acid stinging test with 5% lactic acid solution rather than classic 10% solution because of strong reaction in Asian populations. Transepidermal water loss (TEWL), skin hydration, sebum content, and pH were measured using the bioengineering instruments in an environment-controlled room. Correlations between stinging responses and skin biophysical parameters were statistically analysed. There was a positive correlation between stinging responses and TEWL evaluation. However, no correlations was observed between stinging responses and other parameters such as skin hydration, sebum content, and pH. Our data indicate that there is a relationship between the degree of stinging and the skin barrier function. However, we believe that various additional studies are necessary to characterize skin of stingers and the pathogenesis.
