Description
Sensitive skin is a hyperactive skin condtion, characterized by prickling, burning, itching, stinging, pain, or tingling sensation, which develops in response to various internal and external stimulants that can be tolerated by most people. The pathophysiology involved in the development of sensitive skin remains largely elusive. To characterize differential gene expression profiles in sensitive skin, we investigated the genome-wide patterns of gene expression from skin samples from subjects with sensitive or non-sensitive skin, following lactic acid challenge or normal saline application using cDNA microarrays.
