Some cleansers make the skin feel 'tight' and some moisturizers make the skin feel 'soft.' Reinhold H. Dauskardt and colleagues traced the mechanisms by which applying cleansers or moisturizers to the skin results in such sensations, using in-vitro biomechanical testing, computational neural stimulation modeling, and self-assessment surveys completed by thousands of participants.
Describing sensory neuron activity from biomechanical changes of skin. a) Schematic of SA I neural signals from the skin to the somatosensory cortex of the brain. A Merkel cell at the epidermal-dermal junction with its mechanically gated ion channels is depicted. Firing rates measured from indenting primate fingertips are shown with the corresponding computed firing rates based on FE simulations. b) Depiction of the cutaneous mechanoreceptors in the epidermis and dermis of human skin.
The authors found strong correlations between the physical stress that results in the stratum corneum during post-cleaning drying or moisturizing and the firing rate of neurons located much deeper in the skin near the dermal-epidermal junction.

Study shows that perception is driven by variability of neural activity in the sensory cortexThe brain is a sophisticated biological system known to produce different experiences and perceptions via complex dynamics. Different brain regions and neural populations commonly work in tandem, communicating with each other to ultimately produce specific behaviors and sensations.
