Why does chronic use of tactile desensitization creams, like those containing high concentrations of benzocaine, increase the risk of accidental injury in patients?

💡 Explanation

Tactile desensitization creams reduce nerve sensitivity by inhibiting the activation of mechanoreceptors in the skin. Because mechanoreceptors are crucial for sensing pressure and temperature, their impairment reduces the perception of harmful stimuli; therefore, the user may fail to detect excessive heat or pressure, leading to injury, rather than other neural or immunological pathways being directly affected.
