Air pollution, Autophagy and Skin Aging
Ambient particulate matter (PM) represents an environmental threat to which millions of people worldwide are exposed. Adverse effects of PM on human health have been reported, but its effect on skin aging has not been widely studied. Autophagy is… one of the survival mechanisms for cells during extrinsic and intrinsic stress.
Conclusion: Fibroblasts [cells in connective tissue that produce collagen and other fibers] exposed to PM showed signs of aging which indicate that air pollution might influence skin aging.
