However, the permeability of skin poses a challenge for TDDS, as it is impermeable to large molecules and hydrophilic drugs but permeable to small molecules and lipophilic drug. To overcome this barrier, researchers have investigated vesicular systems, such as transfersomes, liposomes, niosomes, and ethosomes.
