Lipid nanoparticles are an alternative carrier system to liposomes and emulsions. This review paper focuses on lipid nanoparticles for cosmetic and topical application. Production of lipid nanoparticles and final products containing lipid nanoparticles is feasible by well-established production methods. Lipid nanoparticle exhibit many features for topical application of cosmetics and pharmaceutics, i.e. controlled release of actives, Physical and chemical stability of active pharmaceutical ingredients, drug targeting, occlusion, film formation and associated with it penetration enhancement and increase of skin hydration. Due to the production of lipid nanoparticles from physiological and/or biodegradable lipids, this carrier system exhibits an excellent tolerability. The lipid nanoparticles are a “nanosafe” carrier. Furthermore, an overview of the cosmetic products currently on the market is given and the improvement of the benefit/risk ratio of the topical therapy is shown.
