Background: The health area in its most diverse fields has progressively incorporated nanotechnology
into its products, such as in dermatology. In this sector, nanoparticles are one of the strategies
that allow improvements, both in terms of value-added, as well as the efficacy, safety and stability
of products for cosmetic or therapeutic purposes.
Objective: To understand the scenario of development and innovation of dermatological products with
nanoparticles, through a patent prospection, evaluating the annual evolution, the main technology investors
countries, the profile of the depositors, besides the uses and purposes of the products.
Methods: The Espacenet® database was used for consultation, using the search term "nanoparticle and
skin". A total of 285 patents were found, of which 208 were available and 89 were based on the scope.
Results: There was a progressive evolution in the number of patents after the year 2000, with South
Korea, the United States, China and Japan as the main depositor countries. Private companies and Education
and Research Institutions were the entities with the largest amount of deposits. The cosmetic
purpose was the predominant use compared to the therapeutic one. The most prominent nanoparticles
were polymeric, metallic and lipid, while the therapeutic area presented a larger number of the functionalized
Conclusion: The market for dermatological products has been innovating and growing over the years
through the use of nanoparticles, evidencing a prominent development of nanotechnology-based cosmetics.
Countries investing in nanotechnology and major developers of innovative products are highlighted
in this scenario.
