Electroporation is the other strategy which relies on utilization of whether short (micro-to milli-second), or high-voltage electrical pulses to generate transient pores in the composition of the stratum corneum [3].
TEWL through the stratum corneum and skin appendages under non-sweating conditions is the imperceptible water loss.4 It is a true reflection of stratum corneum barrier function, when there is no sweat gland activity.
Moreover, we observed that skin damage, such as elimination of the intercellular lipid lamellae in the stratum corneum, was remarkably reduced in the AT group as compared with AE group (Figure 5).

The decreased level of NMF results in a change of pH in stratum corneum, which may affect the activity of KLK5, 7 and injure the skin barrier further.[sup][35]
Too little moisture causes the stratum corneum to shrink and makes the skin appear cracked.1
The anti-inflammatory effect was found in the treatment with both particle sizes BetaNP1000 (1000 nm), and BetaNP100 (100 nm), however, the therapeutic response was much higher with the BetaNP100, due to its high diffusion within the stratum corneum (Abdel-Mottaleb et al, 2012).
Emollients soften while moisturisers add moisture (Lawton 2009) and work to increase the hydration of the stratum corneum by occluding the skin's surface so that water is not lost.
Then it was mounted on the Franz-type diffusion cells with the stratum corneum side facing upward into the donor compartment.
