Macro, Micro, Nano
How small is a nanometer? Stepping down in size by powers of 10 takes you from the back of a hand to, at one nanometer, a view of atoms in the building blocks of DNA. The edge of each image denotes a length 10 times longer than its next smallest neighbor. The black square frames the size of the next scene inward.
Be skincare uses plant nutrients in carriers the size of 35 nanometers, so that it can enter your skin pores which are 50 nanometers in size.
