How Nanosized Particles May Affect Skin Care Products
Friday, September 16th, 2011How Nanosized Particles May Affect Skin Care Products
The rapidly growing field of nanotechnology and its future use in cosmetic products holds both enormous potential and potential concern for consumers. Currently, major cosmetic manufacturers have imposed a voluntary ban on the use of nano-particles in products while they await a ruling from the Food and Drug Administration (FDA) regarding the safety of this technology.
However, these manufacturers know that when ingredients in products such as sunscreens and anti-aging products are converted into nano-sized particles, the end product displays unique properties that can benefit the skin in ways that otherwise could not be achieved using larger-sized particles.
Speaking at a past Annual Meeting of the American Academy of Dermatology (Academy), dermatologist Adnan Nasir, MD, PhD, FAAD, clinical assistant professor in the department of dermatology at the University of North Carolina in Chapel Hill, presented an overview of nanotechnology and how nano-particles may eventually be used in cosmetic products.
“Research in the area of nanotechnology has increased significantly over the years, and I think there will be considerable growth in this area in the near future,” said Dr. Nasir. “The challenge is that a standard has not been set yet to evaluate the safety and efficacy of topical products that contain nanosized particles.” (more…)
