Numerous studies have shown that photonics can be used in the production of color cosmetics, and photon makeup can mimic the color effect on butterfly wings, bringing revolutionary breakthroughs in color production. In general, products that do not contain or contain a small amount of colorant can exhibit better color and match the color of the skin. This is mainly because the natural world has created almost transparent colors. It is well known that light is a product of the interaction of matter such as pigments with light, and the natural world also provides us with countless colors of pigment-free substances. For example, soap bubbles have a rainbow-like color, and when viewed from different angles, they will have distinct color effects. Butterfly wings, cream glass, peacock feathers and many other things tell us the fact that although these substances do not contain anything related to color, they can present a wonderful world of colorful colors. Therefore, the color is determined by the interaction of light and material structure on the submicron level. In the case of butterfly wings, Peter and Roe, physicists at the University of Exeter in the United Kingdom, spent three years studying the structural features of butterflies and moth wings. They found that when the big butterfly was observed from different angles, its iridescence would undergo an amazing change, due to the so-called "structural color" - the color formed by multiple reflections of light inside the object. The butterfly wings consist of several layers of scales that are only 3 to 4 microns thick. These scales overlap like tiny roof tiles, and the structure of each scale is complex. The orderly arrangement of butterfly wings forms a so-called photonic crystal that captures light and transmits only light of a certain wavelength. Inspired by this blue big butterfly, European scientists have been researching for a few years to introduce bionic photonic cosmetics, which can make light on human lips and eyelashes, like light makes butterfly wings and peacock feathers shine. The same, let us bloom beautiful brilliance. These findings also mean that makeup can also produce color effects that match the human skin without using any coloring ingredients. L'Oreal, the French cosmetics giant, has always been a leader in the makeup industry. L'Oreal researchers at L'Oreal have developed synthetic photonic crystals and applied them to cosmetics. They have developed photon lip gloss, photon mascara, photon eye shadow and photon nail polish, etc. The samples are brilliant in daylight and the effect is amazing. . It uses the refraction of light instead of the traditional pigment to enhance the makeup effect, revealing the mystery of natural phenomena, combined with nanotechnology, will bring a huge breakthrough for cosmetic technology. Pineau, R&D manager of L'Oréal, said that this technology uses light to create color, by dividing the structure of the raw materials, and using nanotechnology to control the color effect, because under the light, the gap between different color layers and the different color layers themselves May affect the final color effect. Peter's team used SEM and TEM microscopy techniques to study the organizing matter of plants and minerals and how to control the photon flow to produce brilliant color effects and unique visual effects. This technology is undoubtedly a good news for the production of cosmetics, especially lipstick. It seems that the white lipstick wipes no color marks on any surface, but it gets the best color effect. It also means that the grease currently used to produce a bright color effect can be avoided from this lipstick formulation. At the same time, the development of this technology will also bring additional color texture and activity to the makeup. But research shows that the new photonic cosmetics are also flawed, that is, it must be done with the help of daylight, if it is in a dimly lit room, it can hardly be seen. In addition, this make-up is best for those darker skins, so further research can greatly advance the development of the ethnic cosmetics market.
