If you’ve been following the newest trends in skin care, you’ve probably heard of a new term: nanotechnology.

Nanotechnology is a new buzzword in skin care and the cosmetics industry; it refers to the use of very small molecules to help deliver treatments below the skin’s surface.

The biggest complaints about nano-molecules is that they behave differently than their normal-sized counterparts.

This may have adverse reactions for the skin or the environment. For example, one type of nano-particle conducts electricity at nano-size, but does not conduct electricity at full-size.

If this particle were added to cosmetics or skin care products, it may have damaging effects for the individual applying it.

Since many cosmetics and supplements can be sold without FDA approval, this may become a growing issue as nanotechnology allows chemicals to be delivered deeper and deeper into our bodies.

The FDA has created a special group to focus on nanotechnology. We’ll be hearing more about this issue as the science continues to evolve.
