If the presented cosmetic nanomaterial development is allowed to bloom after the currently
ongoing nano toxicity and safety research incentives have had a chance to affect regulations and
guidelines for production and use of nanomaterials, and if the necessary commercial support will
be in place to take the materials presented in recently published scientific articles and granted patents
to the market, we can soon expect a range of new nanotechnology-based cosmetic products on the
shelves of the nearest drug store. These include new sunscreens containing diamond nanoparticles
attenuating UV radiation and simultaneously removing the free radicals generated by UV light,
long-lasting hair dyes with CNTs providing smoothening, volumizing and anti-damaging effects,
dental-care product scontaining fluoride nanoparticles treating dentin sensitivity by precluding the
