Our news journalists obtained a quote from the research, "The preparation and stability parameters of these nanocarriers have been investigated concerning particle size and zeta potential. The release pattern of the sunscreens from NLC and NE was evaluated in vitro, determining their percutaneous absorption through excised human skin. Additional in vitro studies were performed in order to evaluate, after UVA radiation treatment, the spectral stability of the sunfilters once formulated in NLC or NE. From the results obtained, when incorporated in NLC, the skin permeation abilities of the sun filter were drastically reduced, remaining mainly on the surface of the skin. The photostability studies showed that EHT, DHHB and Tinosorb S still retain their photostability when incorporated in these carriers, while OMC and AVO were not photostable as expected."
According to the news editors, the research concluded: "However, no significant differences in terms of photoprotective efficacy between the two carriers were observed."
