Human skin and micro- and nanoplastics: a mini-review
Summary
This review explores how micro- and nanoplastics interact with human skin, a less-studied route of exposure compared to ingestion and inhalation. Researchers found that tiny plastic particles can penetrate the skin barrier through cosmetics, contaminated water, and airborne pollution. The study suggests that skin exposure to these particles may contribute to overall human microplastic burden, though more research is needed to fully understand the health implications.
Plastic pollution is a worldwide problem. Its extended use has led to human exposure to micro and nanoplastics (MNPs) through inhalation, ingestion, and also through contact with the skin, by direct contact, or because of the pollution of water and air. In general, the adverse effects produced by MNPs on human health are well known, however, they are far from being fully understood. Although it is a less studied route of entry of MNPs into the human body, MNPs can enter the body through the application of cosmetics and other skincare products. Recent research has found a relationship between skin exposure to MNPs and diseases, like skin cancer. The present work reviews published studies, since 2019, related to the entry of MNPs through the skin and its impact on human health.

Penetration of Microplastics and Nanoparticles Through Skin: Effects of Size, Shape, and Surface Chemistry
This review examines how micro- and nanoplastics can penetrate human skin, with smaller particles being more likely to pass through. Beyond direct toxicity, these tiny plastic particles may also carry harmful chemicals through the skin barrier, acting as unwanted delivery vehicles for toxic substances we encounter in the environment.
Understanding the Risk of Microplastic Dermal Absorption
This review examines the understudied pathway of microplastic absorption through the skin, highlighting a significant research gap compared to inhalation and ingestion routes. Researchers analyzed the potential mechanisms by which small plastic particles in skincare and cosmetic products could penetrate skin barriers. The study calls for more research into dermal absorption risks, particularly given the continued growth of the personal care product industry.
[Microplastic and skin-an update].
This review summarizes current evidence on microplastics (1–5000 µm) and nanoplastics as skin-relevant pollutants, covering how they enter and interact with skin tissue. Evidence suggests dermal uptake is possible, particularly through damaged skin, and that these particles may carry additional chemical hazards.
Microplastics and Nanoplastics Contamination
This review summarizes the state of knowledge on human exposure to microplastics and nanoplastics, covering ingestion, inhalation, and skin contact as entry routes, and detailing how these particles have been detected in human blood, organs, and the placenta. The evidence points to chronic health risks including oxidative stress, inflammation, immune disruption, and potential genotoxicity, with the skin identified as an underexplored but potentially significant exposure pathway.
A review on microplastics and nanoplastics in the environment: Their occurrence, exposure routes, toxic studies, and potential effects on human health
This review summarizes what is known about how microplastics and nanoplastics enter the human body through food, air, and skin contact, and what they do once inside. Studies on cells and animals show these tiny particles can cause oxidative stress, DNA damage, inflammation, and harm to the immune, digestive, reproductive, and nervous systems. The research makes clear that microplastics are not just an environmental problem but a direct concern for human health.
