Microplastics, Skin Disease, and Dermatology: Evidence and Perspectives

Area of Science:

• Environmental Science
• Dermatology
• Toxicology

Background:

• Microplastics and nanoplastics (MNPs) are pervasive environmental contaminants.
• Skin exposure to MNPs is possible, with penetration enhanced by a compromised skin barrier.

Purpose of the Study:

• To review the potential risks of MNPs to skin health.
• To highlight the need for dermatological consideration of MNPs in skin homeostasis.
• To advocate for further research and sustainable alternatives.

Main Methods:

• Review of in-vitro studies on MNP effects on skin cells.
• Analysis of potential MNP penetration through the skin barrier.

Main Results:

• In-vitro studies indicate MNPs can induce oxidative stress, inflammation, and fibroblast senescence.
• MNPs may disrupt skin homeostasis, particularly with impaired skin barrier function.

Conclusions:

• Dermatologists must consider the impact of MNPs on skin health.
• Promoting responsible plastic use and disposal is crucial.
• Research into plastic-free or biodegradable alternatives is essential to mitigate risks.
