the skin so that the use of cosmetics is maximized. An example is the

Nano Gold product produced by KECE Unesa.
The image below is an example of a product that utilizes

nanotechnology in the cosmetic field. The manufacture of cosmetics
with nanoparticles or commonly called nanocosmetics can maximize

the performance of the active substances contained in these
cosmetics. With a very small size, the active substance is easier to

enter into the lowest layers of the skin so that the use of cosmetics is

maximized. An example is the Nano Gold product produced by KECE
Unesa.

The Nano Gold product contains a certain number of gold

atoms that have a diameter of 1-100 nanometers (10 meters). With
-9
this very small size, gold atoms can easily enter the pores of the skin.

Gold itself is proven to improve blood circulation, the possibility for
the use of the skin to be greater. Because by improving blood

circulation, the supply of oxygen to skin cells becomes good and helps
the growth of new skin cells. Nanogold functions as an antioxidant

that reduces free radicals 3-5 times stronger than Vitamin C and
Vitamin E and can increase the proliferation of fibroblast cells or skin

cells and can also increase collagen density.
