[49] One study compared The 2 designs and recorded data that confirmed spherical particles Situated deep during the epidermis and dermis whereas ellipsoidal particles were being generally located in the stratum corneum and epidermal levels.[forty nine] Nanorods are Employed in experiments thanks to their exceptional fluorescent properties but have demonstrated mediocre penetration.
