There has been so much buzz over the use of nanotechnology, or “penetration enhancers” in skin care over the last few years. Nanotechnology utilizes extremely small particle sizes (only a billionths of a metre) to drive “active” ingredients deeper into the skin. Many products containing nanotechnology also come with hefty price tags. It is not uncommon to find anti-aging face creams selling well in excess of $100.00 a jar. Nanotechnology is also used in some sunblocks containing zinc oxide and titanium dioxide as they may help diminish that white “chalky” look.
The debate centers on whether or not nanoparticles can actually penetrate past the outer layer of skin into the bloodstream and possibly interact with the immune system. Theoretically, if this is true, then toxic ingredients encapsulated into nano form could potentially do harm.
The “experts” have mixed opinions. Some preliminary studies suggest that nanoparticles may illicit an inflammatory response and lead to possible cancer or genetic disorders, particularly from ingesting these particles. Of particular concern is the use of spray on products, such as sunblocks or sunscreens which may be inhaled upon application.
The FDA does not have any specific regulations regarding the monitoring of nanoparticles. They generally only investigate if a problem (s) has been reported after a product has been introduced into the market.
The nanoparticle debate continues on both sides of the Atlantic. Recently, a center opened in Scotland specifically to address the safety of nanoparticles.
So, while the jury is still out, doesn’t it make more sense to avoid products with nanotechnology until more research is done?
At La Vie Celeste, we never use nanoparticles in any of our products. And, the anti-aging results our customers have experienced have been spectacular!
