Nano carrier molecules increase UV protection in sun care
The incorporation of sunscreens into nano lipid carrier molecules could increase their effectiveness, whilst reducing the possibility of undesired side effects, according to a recent study.
Research has been ongoing regarding the use of lipid carriers for sunscreen molecules, as it is thought they increase the product's effectiveness whilst decreasing potential absorption and therefore negative side effects.
However creating formulations with higher SPF values has proved difficult.
Recent work published in the International Journal of Cosmetic Science describes the use of solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC) that can be loaded with significantly higher levels of sunscreens than previous attempts, leading to higher SPF factors.
