Microplastics are tiny fragments of plastic that can enter the human body via food, water, and air. As microplastic exposure to humans has been increasing, there have been more human health issues caused by it. Major health problems include inflammation, cell injury, and disruption of the gut microbiome, which can in turn affect digestion and immunity. Some plastics contain toxic chemicals like BPA that interfere with hormones, which may affect fertility and development. Microplastics inhaled into the body can also trigger respiratory problems, and current research suggests that microplastics may affect the brain and even develop cancer. As much additional research is still needed, microplastics are already found to be present in human blood, lungs, and placenta, raising severe health issues.

Additionally, some microplastics contain or take up toxic chemicals like phthalates and bisphenol A (BPA), which are known endocrine disruptors. These chemicals can interfere with hormone regulation, with downstream effects on aging processes like metabolism, reproductive function, and cognitive function. Although direct evidence for the role of microplastics in premature aging in humans is still forthcoming, the detection of microplastics in human tissues and their biological effects are cause for concern about their long-term effects on health and aging.

Microplastics-induced chronic inflammation and oxidative stress can activate premature skin aging, including wrinkles, reduced elasticity, and dullness. These processes target the destruction of collagen and elastin—well-known proteins responsible for young and firm skin. Endocrine disruption by chemicals from plastics like BPA and phthalates can lead to skin conditions like acne, dryness, or discoloration and can also cause hair thinning or texture change. They also affect internal systems—immune system, hormone balance, and cell health, which can show up in signs of aging or impaired skin condition. These subtle yet continuous changes may lead someone looking older than their actual age.
