Cytotoxicity of Nanoparticles Used in Cosmetic Industries: An In-depth Insight
Summary
This review examined the cytotoxicity of nanoparticles used in cosmetic sunscreens, including titanium dioxide and zinc oxide, finding that while these particles provide effective UV protection, their nanoscale form raises concerns about skin penetration and potential cellular toxicity.
As the incidence of skin malignancies, such as melanoma and nonmelanoma, has increased, so has the use of sunscreens. Sunscreen-mediated photoprotection relies on reducing the effects of UV, especially UV-A and UV-B. Natural & artificial tanning compounds were subdivided. Aqueous or chemical products are indeed the names mentioned in organic sunscreens. Physical, mineral, insoluble, natural, and nonchemical are all terms used to describe inorganic sunscreens. During the last decade, Octyl methoxycinnamate (OMC) was used in 90% of sunscreens as a UV filter. Organic sunscreen formulations were dominant, and this only changed in the 1990s when inorganic sunscreens started to be preferred due to their higher effectiveness. These contained microfine powders of Titania (Titanium Dioxide-TiO2) & Zinc Oxide (ZnO). The presence of these nanoparticles, however, can have several downsides. So, by removing the hazardous entities from the materials used in cosmetics industries and with the use of some nature-based materials, cytotoxicity will be removed.

Recent developments in sunscreens based on chromophore compounds and nanoparticles
This review covers recent advances in sunscreen formulations using nanoparticles and light-absorbing compounds. Researchers found that nanoparticles like zinc oxide and titanium dioxide can effectively scatter and absorb UV radiation while remaining cosmetically appealing, and that encapsulating UV-absorbing compounds in nanoparticles can enhance protection. The study also highlights progress toward more photostable, broad-spectrum, and environmentally friendly sunscreen options.
Photodegradation of Microplastics by ZnO Nanoparticles with Resulting Cellular and Subcellular Responses
Researchers extracted both zinc oxide nanoparticles and microplastics from a commercial sunscreen and found that the zinc oxide accelerated the breakdown of microplastics under simulated sunlight. However, the degradation products proved toxic to human skin cells at certain concentrations, causing oxidative stress and DNA damage. This suggests that while sunscreen ingredients may break down microplastics, the resulting fragments could pose their own health risks.
Differentiation of cellular responses to particulate and soluble constituents in sunscreen products
This study separated sunscreen products into their particle and dissolved components to understand which parts cause cell damage. Researchers found that dissolved chemical ingredients were the main drivers of overall toxicity, while solid particles, including microplastics and zinc oxide, primarily caused damage at the subcellular level. The work highlights that microplastic beads in sunscreens can alter how other ingredients are absorbed by cells.
Modulation efficiency of clove oil nano-emulsion against genotoxic, oxidative stress, and histological injuries induced via titanium dioxide nanoparticles in mice
Researchers found that titanium dioxide nanoparticles (used widely in sunscreens and food products) caused DNA damage, oxidative stress, and organ tissue injury in mice, but that a clove oil nanoemulsion significantly reversed these harmful effects — suggesting a natural antioxidant treatment may protect against nanoparticle toxicity.
