Are Nanoparticles In Skin Care Really Safe? Looks Like The Jury Is Still Out Lately there has been much controversy regarding the safety of nanoparticles in skin care. The use of nanoparticles Liquid sulfur dioxide has become one of the hottest crazes in the anti-aging skin care market. They are frequently used in anti-aging creams and sunscreens (particularly those using zinc oxide and titanium dioxide). Nanotechnology usually comes with a steep price tag; it is not unusual for a luxury face cream to cost in excess of $100.00. Nanoparticles are tiny particles which measure one billionth of a meter.
They are much smaller than particles traditionally used in skin care. The rationale for using nanotechnology is that the smaller particle size will increase the effectiveness of the product. The debate centers on whether or not these particles can actually penetrate past the outer layer of skin into the bloodstream and possibly interact with the immune system. And if they can, then what harm can they do to our bodies if these ingredients are potentially toxic?
The findings of a new study conducted by the University of California, Los Angeles, published in the Journal of Cancer Research suggested that when mice ingested nanoparticles it lead to genetic damage. Based on the findings, the authors warned against the ingestion of food colors, non essential drug additives and vitamins that contain titanium dioxide nanoparticles. They also warned against using spray on sunscreens containing titanium dioxide nanoparticles since they can be easily inhaled.
