You can expect healthy, functional skin to be sensitive to its surroundings and reactive in the instances where it is truly in danger. It is only doing its vital job of being a continually transforming barrier (with a communication element) that is your body’s first line of defense.

Though they both present in a similar way (which is often referred to as “sensitivity”) the underlying conditions differ, so finding relief in each instance may take a slightly different path.
