Skin photoprotection improvement: synergistic interaction between lipid nanoparticles and organic UV filters.


A photoprotective formulation was developed with an increased sunprotection factor (SPF), compared to a conventional nanoemulsion, but having the same concentration of three molecular sunscreens, namely ethylhexyl triazone, bis-ethylhexyloxyphenol methoxyphenyl triazine, and ethylhexyl methoxycinnamate. The sunscreen mixture was incorporated into… (More)
