Getting to the truth about the use of nanoparticles in cosmetics, like many issues in the cosmetics industry—with its confusing screen of distorted information—isn’t easy. But getting it right is important, particularly because the sunscreen ingredients titanium dioxide and zinc oxide, so essential to the health of skin, are involved. Nanotechnology is about changing any material from its original size and making it much, much smaller. This technology is used in a wide variety of industries, from medicine to agriculture to cosmetics. In the case of cosmetic products and over-the-counter drugs such as sunscreens, making particles nano-sized has two chief advantages: it can make the product more aesthetically pleasing (this is often the case with mineral sunscreens—making the particles of the active mineral smaller allows them to be applied without leaving a noticeable white cast), and it can enhance penetration of certain ingredients, such as vitamins
and other antioxidants.
