A detailed review of the literature is presented in
attempts to emphasize several advantages of solid
lipid nanoparticles (SLN) and nanostructured lipid
carriers (NLC) for cosmetic applications. Examples
of several actives are given and the main features
of the solid core of SLN and NLC for topical delivery
of cosmetics are discussed. Lipid nanoparticles
have been more and more explored in pharmaceutical
technology, showing superior advantages
for topical purposes over conventional colloidal
carriers.
